Breast cancer is the most frequent feminine cancer in France and its incidence increases steadily. The time of access to medical care is an indicator of the quality of the treatments recommended by the Plan Cancer 2009-2013, as it influences the diagnosis and reduces psychological morbidity during the pre-diagnosis phase. The one-day diagnosis is a recently initiated concept, which offers to get the results of the biopsy on the day it is performed and facilitates the setting-up of therapeutic care with the surgeon met during the one-day medical consultations. The aim of this study is to evaluate the satisfaction of patients who benefited from a one-day breast lesion diagnosis, as well as confirm the decrease of time of access to medical treatment.This is an observational, non-interventional and single-centre study based on 27 patients who benefited from one-day breast lesions diagnosis over two years. The patients were only included who had a classified lesion ACR 4 or 5 and visible in the ultrasound. We analyzed the histological concordance between the biopsy and the definitive histology, the time of access to medical care, and the therapeutic treatments We analyzed the psychological impact of such an organization by sending to the patients a questionnaire including the Psychological Consequence Questionnaire (PCQ) and the Breast Cancer Anxiety Indicator (BCA) allowing to estimate the anxiety generated by the pre-diagnostic phase, the DC-Sat allowing to estimate the satisfaction of the consultation of announcement, as well as the same day diagnosis benefit.The patients were 59.8 years old in average [33-87]. The average time between the date of the mammography and the one-day diagnosis consultation (including the biopsy) was 15.0 days [0-60]. Fifty-seven percent of the patients considered this time as short. The average time between the biopsy date and the start of the treatment was 15.9 days [4-30]. The one-day diagnosis took an average of 1.6 days [1-5]. The results of the PCQ showed an important emotional impact during the diagnosis phase, and the average BCA score reached an average of 3.9 on a scale of 5. However, the patients were very satisfied with the diagnosis consultation with an average of 8.7 on a scale of 10, and 95% think the one-day diagnosis is beneficial to the patients.This study shows that the one-day breast-damage diagnosis enables to improve the time of access to care, and meets the current recommendations. Even though faster access to treatment does not reduce the psychological morbidity of awaiting diagnosis, the patients express their satisfaction and find the rapidity of the pre-diagnosis phase beneficial.In view of this study, the one-day breast-damage diagnosis appears to be a quality feature in the process of access to care and treatment of the patients.

The purpose of this article is to review the diagnostic work-up of renal failure, acute or chronic. The role of the radiologist is to exclude the presence of a curable etiology such as urinary tract obstruction or vascular thrombosis. Renal ultrasound with Doppler imaging is the imaging modality of choice for this indication, and the use of a contrast agent is useful to evaluate renal perfusion. Non-contrast CT remains valuable for the diagnosis of some urinary tract pathologies. Finally, MRI is the most comprehensive imaging modality for the evaluation of the urinary tract, but performed as a second line modality mainly for practical reasons but also due to the non-negligible risk of nephrogenic systemic fibrosis secondary to the intravenous administration of gadolinium based contrast agent.

Extravasation of contrast material is a well-recognized complication of contrast-enhanced imaging studies. The management of this complication is contentious; therefore, the Contrast Media Safety Committee of The European Society of Urogenital Radiology decided to review the literature and issue guidelines. A comprehensive literature search was carried out. The resulting report was discussed at the 8th European Symposium on Urogenital Radiology in Genoa, Italy. Automated power injection may result in extravasation of large volumes and may or can lead to severe tissue damage. Infants, young children and unconscious and debilitated patients are particularly at risk of extravasation during contrast media injection. Fortunately, most extravasations result in minimal swelling or erythema, with no long-term sequelae; however, severe skin necrosis and ulceration may occur. Large volumes of high osmolar contrast media are known to induce significant tissue damage. Compartment syndrome may be seen associated with extravasation of large volumes. Conservative management is often adequate, but in serious cases the advice of a plastic surgeon is recommended. Based on the review simple guidelines for prophylaxis and management of contrast medium extravasation injuries are proposed.

We report a case of benign colonic tubular adenoma arising in a 36-year-old female at the site of ureterosigmoidostomy performed 25 years before. The tumor was revealed by recurrent episodes of pyelonephritis; hydronephrosis was present. On colonic enema, the tumor appeared lobulated, 4 cm in diameter. CT scan showed a multiloculated mass, which enhanced after injection. Pathology revealed a tubular adenoma of the colon with cystic dilatation of glandular structures. The role of imaging studies in the follow-up of patients after ureterosigmoidostomy is discussed.

An unusual case of spontaneous intraperitoneal rupture of the ureter was observed in adult with acute renal pain. Diagnosis was best established with CT rather than intravenous urography. CT demonstrated ureteral leakage with the contrast medium extravasating into the peritoneal cavity. The patient was initially managed successfully by endourology. Secondary stenosis of the ureter required surgery for partial resection of the distal ureter.

PURPOSE: To evaluate treatment of osteoid osteoma with computed tomography (CT)-guided percutaneous excision and immediate follow-up scintigraphy. MATERIALS AND METHODS: Sixteen consecutive adolescent and adult patients underwent CT-guided percutaneous excision of a nidus with 14-gauge biopsy cutting needles, with local anesthesia. After the presence of nidus was confirmed at immediate follow-up scintigraphy, curettage of the bored cavity was performed to remove any residual fragments of the nidus. Scintigraphic and histologic findings were correlated. RESULTS: The nidus was removed successfully in 14 of the 16 patients, with no complications (mean follow-up, 15 months; range, 3-25 months). In five of the 14 patients, immediate follow-up scintigraphy showed incomplete resection of the nidus and immediate second resection was successful. Surgical resection was necessary in two of the 16 patients. CONCLUSION: CT-guided percutaneous excision with immediate follow-up scintigraphy was safe and effective for lo...

Sclerosing mesenteritis is an uncommon condition of unknown etiology. It is likely to be the fibrous evolution of mesenteric panniculitis. It often has an indolent course but may be complicated by progressive bowel obstruction. The treatment of the symptomatic forms is not well established. The observations of two women (20 and 65 years old) with a relentless downhill course of biopsy-proved sclerosing mesenteritis are described. A treatment regimen with corticosteroid therapy (initially 1 mg/kg/day) and colchicine (1 mg/day) led, in both cases, to a rapid improvement. Abdominal computer tomography showed reduction in the tumor size. The combination of corticosteroids and colchicine is helpful in the management of symptomatic sclerosing mesenteritis. Follow-up with abdominal computed tomography is useful in evaluating the therapeutic impact.

Among all noninvasive techniques, high-resolution ultrasonography used alone has rarely been used for the diagnosis of thrombosis in the calf. Nineteen patients with suspected AVT were examined with ultrasonography and phlebography during 4 months. For each patient, a sonogram and a phlebogram were taken within less than 24 hours and interpreted independently. The sonographic exploration with a high-resolution (5 MHz) transducer covers all deep trunks and muscular veins (soleus or gastrocnemius muscles). The positivity criterion is the persistence of a hypoechogenic endoluminal image under moderate compression. According to the phlebographic data, 65% of the patients present with thrombosis. Ultrasonography has a sensitivity of 95% and a specificity of 99% for the study of the deep trunks. Ultrasonography screens more thromboses than phlebography (23 cases versus 17). On a whole, ultrasonography seems to be more sensitive than phlebography for the diagnosis of recent sural thrombosis.

The protal system of 45 normal patients have been retrospectively studied on spin echo MRI sequences (interleaved cuts): multiple artifacts have been evaluated and 24% of them were visualized at the portal system level. Thus, partial volume effect responsible for almost 25% of the artifacts is not always easily seen on a single sequence. Respiratory and aortic artifacts can deteriorate the visualization of the vascular lumen but cannot be confused with a thrombosis. Well-known artifacts, as slice entry phenomenon and even echo rephasing, represent more than 60% of the artifacts: they are readily recognized when they are typical and indicate flowing blood. On the contrary, an other artifact, representing less than 5% of the total and seen at the level of the left portal vein, simulates a thrombus, on T2 weighed images. We conclude that the frequency and polymorphism of the artifacts are limiting factors of MRI value in the diagnosis of portal vein thrombosis.

This observation illustrates the use of CT in the diagnosis of rectosigmoid hemangiomas and the assessment of their extension. The CT appearance of hemangiomas is very specific and therefore allows confirming a diagnosis that is often difficult to make with other radiological techniques and with endoscopy: phleboliths within the thickened rectal wall are a characteristic sign. CT is primarily required when radical surgery is contemplated due to disabling repeated proctorrhagia: it provides a better delineation of trans- and extraparietal hemangioma extension, knowing that adhesion (...).

When confronted with rectorrhagia in a young patient, combining a straight abdominal examination with a barium enema investigation may reveal the presence of phleboliths, atypical by their large number and central localization, and orientate towards the rare diagnosis of a colorectal hemangioma.

The assessment of the extent of kidney cancers with MRI and CT is compared in 40 patients. The appearance of the tumor with MRI is very variable but always heterogeneous. Specific MRI features (tumoral pseudocapsule) provide a higher overall reliability (OR) than with CT for the detection of expansion beyond the capsule and into the kidney: 80% for 60%. Although the overall reliability of MRI is similar to that of CT (92% for 86%), MRI has proved its superiority for the assessment of the limits of endovenous tumoral expansion because of natural flow/thrombus contrast and of the multiple incidences of exploration. There is no significant difference between MRI (OR = 91%) and CT (OR = 88%) or the detection of lymph node involvement. Invasion of neighboring organs is better assessed with multi-incidence MRI. According to Robson's classification, the OR of MRI (77%) is not significantly higher than that of CT (65%). MRI is still a time-consuming and expensive technique, which should be reserved for cases in which iodine is contraindicated and used as a second-intention technique after CT to confirm the invasion of the capsule if partial nephrectomy is indicated, or the better delineate venous or regional invasion which CT could not assess properly.

Since diagnostic value of double contrast colon imaging is dependent on the colon preparation used, tolerance and efficacy of 4 colon preparations were evaluated by a simple-blind, comparative, randomized study in 185 outpatients. Colon preparation involves variable combinations of 3 means: residue-free diet, laxatives and wash-out enemas. Principal criteria were evaluated under blind conditions by the same investigator during all examinations, with quantitative rating by segment (left, transverse and right colon) of adherence and colon cleanliness, and global assessment of quality of preparation. The 4 groups were comparable: mean age 44.7 years, sex ratio (male/female) 51.3%. Tolerance and compliance were elevated without significant inter-group differences. The colon preparations studied did not allow a homogeneous preparation to be obtained throughout the colon, efficacy in left colon being superior to right colon, whatever the method used. Analysis of cleanliness and adherence by segment failed to show significant differences between procedures, probably related to weak differences in their effectiveness and the strict nature of the study. The use of a global criterion tended to show value of wash-out enemas as a routine procedure, whether in outpatients or in the Radiology department.

A case of encapsulating peritonitis complicating the course of familial Mediterranean fever is reported. This encapsulating peritonitis was responsible for abdominal pain and had a "pseudocystic" appearance on ultrasonography and computed tomography. Ultrasound guided aspiration produced a yellowish fluid rich in proteins and poor in cells. Surgical operation revealed a congested appearance of the peritoneum associated with a richly fibrinous appearance of the external wall of the mass. The differential diagnosis is discussed.

Twelve cases of recurrences of Hodgkin's disease on the chest wall, associated with three breast lesions and three diaphragmatic lesions, were studied by computed tomography (CT). Although the chest radiographs of all the patients were abnormal, CT was more accurate than clinical and other radiological examinations in delineating the lesions of the chest wall and in studying the extension of the relapse. Muscle enlargement was present in all cases. In seven cases osseous lesions and in seven cases pleural effusion or subpleural plaques were found. Chest wall recurrences were associated with other thoracic or abdominal lesions in 75% of the cases. Recurrences to the chest wall occur late (mean 6.3 years) in the evolution of Hodgkin's disease. They developed during the first relapse in 67% of the cases and during the second to the fourth relapse in 33% of the cases. CT is useful for the screening of lesions for which the outcome is bad. Only in four cases patients were without any evidence of disease after treatment.

Nineteen cases of focal infectious lesions of renal parenchyma studied included 10 cases of acute focal bacterial nephritis (AFBN) and 9 of abscess, cases of pyelonephritis without radiological signs being excluded from this report. Each patient had been investigated by intravenous urography (IVU), ultrasound and CT scan imaging. Comparison of value of the different radiological explorations showed that urographic signs were inconstant and only weakly specific, the most valuable examination being CT scan imaging. The latter images show hypodense zones, clearer with contrast, of a rather triangular form and either single or multiple in AFBN, and mainly nodular images in abscess cases. Ultrasound is of intermediate value, being of high performance in cases of abscess but failing to demonstrate AFBN in about half the cases. However, it should not be totally neglected because of its case of access.

This report studies the diagnostic problem raised by benign pedunculated gastric leiomyoma identified by CT scan imaging and associated with hepatic metastases. Evaluation of the angle of attachment to the wall, the conventional feature enabling distinction between malignant and benign submucous tumours is not always a reliable indicator.
