The abdominal microsurgical flap based on the deep inferior epigastric artery perforator (DIEP) flap has become the most popular option worldwide for autologous breast reconstruction. Several authors have investigated the results of reconstructed breasts, but the literature lacks systematic reviews exploring the donor site of the abdominal wall. To fulfil our aims, a new diagnostic muscle imaging analysis was designed and implemented. This study focused on rectus abdominal muscle morphology and function in a single series of 12 consecutive patients analysed before and after breast reconstruction with a microsurgical DIEP flap. Patients were divided into two groups, namely, "ipsilateral reconstruction" and "contralateral reconstruction", depending on the side of the flap harvest and breast reconstruction, then evaluated by computed tomography (CT) scans scheduled for tumor staging, and clinically examined by a physiatrist. Numerous alterations in muscle physiology were observed due to surgical dissection of perforator vessels, and rectus muscle distress without functional impairment was a common result. Postoperatively, patients undergoing "contralateral reconstruction" appeared to exhibit fewer rectus muscle alterations. Overall, only three patients were impacted by a long-term deterioration in their quality of life. On the basis of the newly developed and implemented diagnostic approach, we concluded that DIEP microsurgical breast reconstruction is a safe procedure without major complications at the donor site, even if long-term alterations of the rectus muscle are a common finding.

We evaluated differences in density and 18 F-FDG PET/MRI features of lytic bone lesions (LBLs) identified by whole-body low-dose CT (WB-LDCT) in patients affected by newly diagnosed multiple myeloma (MM). In 18 MM patients, 135 unequivocal LBLs identified by WB-LDCT were characterized for inner density (negative or positive Hounsfield unit (HU)), where negative density (HU < 0) characterizes normal yellow marrow whereas positive HU correlates with tissue-like infiltrative pattern. The same LBLs were analyzed by 18 F-FDG PET/DWI-MRI, registering DWI signal with ADC and SUV max values. According to HU, 35 lesions had a negative density (- 56.94 ± 31.87 HU) while 100 lesions presented positive density (44.87 ± 23.89 HU). In seven patients, only positive HU LBLs were demonstrated whereas in eight patients, both positive and negative HU LBLs were detected. Intriguingly, in three patients (16%), only negative HU LBLs were shown. At 18 F-FDG PET/DWI-MRI analysis, negative HU LBLs presented low ADC values (360.69 ± 154.38 × 10 -6  mm 2 /s) and low SUV max values (1.69 ± 0.56), consistent with fatty marrow, whereas positive HU LBLs showed an infiltrative pattern, characterized by higher ADC (mean 868.46 ± 207.67 × 10 -6  mm 2 /s) and SUV max (mean 5.04 ± 1.94) values. Surprisingly, histology of negative HU LBLs documented infiltration by neoplastic plasma cells scattered among adipocytes. In conclusion, two different patterns of LBLs were detected by WB-LDCT in MM patients. Both types of lesions were indicative for active disease, although only positive HU LBL were captured by 18 F-FDG PET/DWI-MRI imaging, indicating that WB-LDCT adds specific information.

The Tauber procedure, i.e., antegrade sclerotherapy for varicocele, can lead to ischemic colitis. The pathogenesis can involve an atypical systemic-portal communication, which could represent an infrequently reported (rare) anatomical variant. The aim of this study is to review clinical cases from the literature to highlight the anatomical bases of such complications. A computer-aided and hand-checked review of the literature was used to identify relevant publications. Also, the computed tomography (CT) examination of a clinical case with medico-legal implications due to severe vascular complication following Tauber's procedure was reviewed. Although specific references to this complication have appeared since the 19th century, reports in the contemporary literature include only a few clinical cases of ischemic colitis following Tauber's procedure. The CT scan images of a filed lawsuit revealed traces suggesting a significant communication between the testicular and left colic veins, forming part of the systemic-portal anastomoses. An anatomical variation consisting of a communication between the testicular and left colic veins has been described from the clinical point of view, corresponding to a significant anatomical finding identified in the past that has been under-reported and its clinical importance subsequently underestimated. For the first time we have demonstrated its pathophysiological significance in a real clinical scenario, linking the anatomical variation to the clinical complication. This demonstrates the importance of raising scientific awareness on this issue to prevent possibly devastating complications in daily clinical practice. Clin.

Aims: Increased extravascular lung water (EVLW) is seen as B-lines on chest ultrasonography. In lowlanders ascending to altitude the time course, relationship with the patient's clinical status and factors affecting B-lines are still unclear. The aim was to monitor B-lines, clinical status and N-terminal B-type natriuretic peptide (NT-proBNP) during exposure to high altitude., Methods and Results: Chest ultrasonography, blood samples, cardiovascular parameters, and signs and symptoms of high altitude pulmonary oedema (HAPE) were prospectively assessed in 19 participants at baseline and after ascent to 3830 m (9, 24, 48, 72 h, and 8 days) by blinded investigators. Potential confounding factors (e.g. altitude variations, physical effort) were minimized. Generalized estimating equations were used to analyse factors associated with B-lines. B-lines changed with exposure to altitude (P = 0.006) in a parabolic-like pattern within the first 72 h; 10 of 18 participants (55.6%) had >5 B-lines at 24 h. B-lines were correlated with the number of signs and symptoms (partial coefficient = 0.372, P = 0.001). B-lines were associated with time (P = 0.038), sex (P = 0.013), and SpO2 (P = 0.042), but not with NT-proBNP (P = 0.546). The participant with a clinical diagnosis of HAPE had 23 B-lines., Conclusion: B-lines during exposure to altitude seem to reflect the individual response to hypobaric hypoxia and represent clinically relevant alterations at high altitude, also in patients with HAPE. Similar to previous studies, our results support a non-cardiogenic aetiology of B-lines., (Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2015.

Nephrogenic adenoma is an uncommon benign lesion of the urinary tract induced by chronic irritation of the vesical mucosa, due to infection, trauma, surgery, calculi, foreign bodies and chemical agents. A 68-year-old male was admitted to our linic for a periodical cystoscopic evaluation as part of a follow-up initiated due to a past transitional cell carcinoma. The scheduled cystoscopy revealed, within a bladder diverticulum, an unexpected and completely asymptomatic nephrogenic adenoma that we removed by transurethral resection. We followed up the patient at 24 months, then later we made the diagnosis of nephrogenic adenoma. During this time, the patient experienced three relapses within the same diverticulum, always involving a nephrogenic adenoma we persistently treated by transurethral resections. As the nephrogenic adenoma is considered a benign lesion without any direct evidence of a possible evolution to an overt cancer, we successful attempted a half-yearly cystoscopic follow-up to control the growth of a highly recurrent benign entity, interposing between controls a periodical imaging. This paper represents the second report of a nephrogenic adenoma within a bladder diverticulum, but the first case of a nephrogenic adenoma highly recurrent within the same diverticulum and managed conservatively by regular transurethral resection scheduled over the time.

A 78-year-old Caucasian man was referred to our department because of an incidental unilateral mass involving the right renal sinus. As the patient showed no urological disease at flexible ureterorenoscopy, a subsequent percutaneous CT-targeted biopsy was mandatory, confirming an aggressive non-Hodgkin disease involving the renal pelvis that is, to the best of our knowledge, the second reported case in literature. A whole body FDG-PET excluded multiple expression of this disease, and the patient underwent a chemotherapeutic scheme resulting in a stable marked reduction in tumor volume. To the date, the available experience on the management and outcome of such cases is extremely lean. In this scenario, our case can contribute to shorten the time-to-diagnosis by reporting a complete images overview comprising abdominal CT scan, MRI and FDG-PET-CT, hence making this clinical entity easier presumable in clinical daily practice and offering a possible suggestion for an effective treatment.

A 78-year-old male presented complaining voiding low urinary tract symptoms associated to genital weightiness over the past few years. Grossly the lesion was only interesting the scrotum, for an about 7.5 kg mass. The scrotum was minimally tender, with an intact skin bereft of erythema or inflammation, lower limb lymphedema, inguinal/crural lymphadenopathy. Despite repeated urinary cytologies were negative, an abdominal CT and urethrocystoscopy confirmed a muscle-invasive transitional cell carcinoma affecting the bladder. The surgical strategy included a direct excision of the giant scrotum with local tissue reconstruction and a radical cystectomy with ileal conduit. This is the first time it's noted a giant scrotal lymphedema as the unique onset sign of a muscle invasive transitional cell carcinoma of the bladder otherwise clinically silent. In this clinical setting, a differential diagnosis has always to be carried out, as bladder cancer is a life-threatening disease requiring an aggressive approach.
