Purpose: Inflammatory breast cancer (IBC) is a rare and aggressive type of breast cancer, as many physicians may not be aware of it in terms of symptoms and diagnosis. Mammography is the first choice in breast screenings and diagnosis. Because of a lack of expertise and imaging datasets, IBC portrayal and machine learning-based diagnosis systems have not yet been studied thoroughly. Developing scanning and diagnosis tools can close the knowledge gap and barriers to a timely IBC diagnosis., Materials and Methods: The dataset includes 20 women aged 34-75, of whom 10 were clinically diagnosed with IBC and 10 with non-IBC. A breast mapping and scanning model was developed. Gray-level co-occurrence matrices were used to characterize skin thickening, edema, breast density, microcalcifications, and breast size asymmetry in bilateral mammographic images., Results: A one-way analysis of variance (ANOVA) test was performed to evaluate differences between mammogram breasts with IBC, non-IBC, and healthy breasts. Higher breast density variations were calculated in breasts with IBC in the anterior (P = 0.0147) and middle (P = 0.0026) regions. Breasts with IBC showed higher microcalcifications (P = 0.0472) than the other breasts, and bilateral analyses showed higher variations (P = 0.1367). Breast size asymmetry (P = 0.9833) was not significantly different between the groups., Conclusion: Skin thickening, edema, and breast density-related parameters were found to be associated with IBC. This study thus lays the foundation of machine learning diagnosis models for IBC., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Associazione Italiana di Fisica Medica e Sanitaria.

Mounier-Kuhn syndrome, also known as tracheobronchomegaly, is a rare clinical and radiological condition characterized by tracheobronchial dilatation and recurrent respiratory infections. Patients may be asymptomatic or present with severe respiratory illnesses. A CT scan is sufficient to confirm the diagnosis. Treatment is symptomatic, and surgery is rarely indicated. We present the case of a 55-year-old patient with a 30-year history of chronic dyspnea, who presented with worsening shortness of breath, a productive cough, and episodes of bronchial superinfection. A chest CT scan, performed before and after contrast injection during both inspiratory and expiratory phases, confirmed the diagnosis of Mounier-Kuhn syndrome. This case aims to raise awareness of this rare condition and highlights a presentation where dyspnea is the primary symptom., (© 2024 The Authors.

Erdheim-Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis. There are few documented cases in the medical literature. Here, we present an infrequent case of a 53-year-old patient who presented with cutaneous xanthelasma and a gradual decline in general health characterized by asthenia, anorexia, and chronic dyspnea over the last 5 years. Chest, abdominal, and pelvic CT scans revealed distinct findings suggestive of ECD, including peri-renal fat infiltration resulting in the "hairy kidney" sign, hepatosplenomegaly, renal artery ostial stenosis, pneumopericardium thickening, interstitial lung parenchymal involvement, metaphyseal-diaphyseal osteosclerosis affecting long bones, and sinus osteosclerosis. A biopsy confirmed the diagnosis. This case highlights the importance of radiologists being familiar with the characteristic radiologic signs of ECD to avoid unnecessary repeat examinations, delays in diagnosis, or misdiagnosis., (© 2024 The Authors.

Tumoral calcinosis is a rare cause of intratissular calcifications in hemodialysis patients with chronic renal failure. Its frequency is estimated between 0.5 and 7% of patients. We illustrate through a case of unusual localization diagnosed in Ibn Rochd University Hospital, Casablanca, Morocco, the radiographic and scannographic aspect of this little known entity. A 40-year-old man, followed for hypertensive cardiopathy, in chronic renal failure for 12 years under hemodialysis, consulted for bilateral inguinal swellings evolving in a progressive and painless way. Biological investigations revealed hyperparathyroidism with increased phosphocalcic product. He was referred to us for radiological evaluation which revealed lesions in favor of bilateral puboinguinal tumor calcinosis. Tumoral calcinosis is a rare cause of intratissular calcifications in chronic renal failure patients undergoing hemodialysis. Pubic localization with infiltration and osteolysis of the symphysis pubis is very rare. Its main risk factors are the existence of hyperparathyroidism, an increase in phosphocalcic product and probably local traumatic factors. Tumoral calcinosis has a typical appearance on radiographs: amorphous, cystic and multilobulated calcifications of periarticular distribution. The CT scan allows a better delineation of the calcified mass. Its treatment remains controversial. The knowledge of osteoarticular manifestations of chronic hemodialysis patients, especially tumoral calcinosis by radiologists, allows to easily make the diagnosis and thus avoid invasive complementary explorations for the patient and to quickly institute an effective treatment., (© 2023 The Authors.

Eccrine porocarcinoma is a rare type of skin neoplasm. It represents less than 0.01% of all epithelial cutaneous tumors. Early diagnosis is the only way to minimize the mortality rate, given its aggressive nature and the high rate of local recurrence and metastasis. Clinical diagnosis is challenging and the confirmation is histological. Few studies have been published about the radiological features of eccrine porocarcinoma. We report a case of a localized eccrine porocarcinoma along with ultrasound, MRI features, and a review of the literature to highlight the role of imaging in the diagnosis and treatment plan., (© 2022 The Authors.

Mycetomas caused by aerobic actinomycetes are called actinomycetomas. It is primarily localized in subcutaneous tissue but it can spread to different tissue planes including the skin, deep tissues and structures and eventually the bones. We report the cases of 2 patients referred for evaluation of soft tissue masses involving the foot. A 40-year-old male and a 25-year-old male, in both cases MRI was performed to assess the extension, which was later completed by a CT scan. MRI revealed a low intensity matrix that represents fibrosis containing multiple high intensity lesions corresponding to the mycetoma grains. Within some of the lesions a low-intensity focus was identified. This "dot-in-circle sign" on an MRI is a pathognomonic feature of mycetoma. The purpose of this work is to describe the characteristic MRI appearance of foot mycetoma., (© 2022 The Authors. Published by Elsevier Inc. on behalf of University of Washington.)

Fibrous uterine polyps are very common in women during or after menopause, and less often seen in women of child-bearing age, with a maximum of frequency between 40, and 49 years. They can have various locations in the uterus depending on the patient's age, mostly the body, and fundus. We report a rare case of cervical localization of a pedicled fibrous polyp issuing from the cervix, in a 44-year-old female patient with 3 living children and a history of miscarriage, who had been presenting breakthrough bleeding, and pelvic pain for 3 months. It is essential to remind young radiologists of the different presentations of fibrous polyps, how to explore them better and when to fear malignancy and thus insist in a histologic study, in order to help clinicians to choose the most adequate treatment option., (© 2022 The Authors.

Leriche syndrome or aortoiliac occlusive disease is a particular obliterative arterial disease of the lower limbs, consisting of thrombotic occlusion of the aortoiliac junction. We here report the case of a 20-year-old female patient with no particular past medical history, presenting with acute lower limb ischemia. Lower extremity echo Doppler showed overall decrease in arterial blood flow without visualization of endoluminal material. Lower limb angioscaner showed arterial thrombosis of the abdominal aorta extended to bilateral external iliac arteries. The patient subsequently underwent aortic-bi-iliac bypass surgery with good evolution as well as assessments for possible thrombogenic mechanism., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Leila Noureddine et al.)

Primary thyroid lymphoma is a rare clinical entity, which does not exceed 5% of the diagnosed lymphomas, occur more frequently in women than in men, with a peak incidence in the sixth decade of life. The relationship with chronic thyroiditis is well known. The Hodgkin subtype even rarer; little described in the literature; Posing a diagnostic problem. Diagnostic confirmation is usually carried out on the surgical specimen. To better understand this entity, we report the case of a 64-year-old patient, with no notion of chronic thyroiditis, admitted for Hodgkin's lymphoma of the thyroid, diagnosed on an anterior cervical mass. Thyroidectomy with histopathological and immunohistochemical studies confirmed the diagnosis. The patient had received chemotherapy type ABVD (Adriblastin-Bleomycin-Vinblastine-Dacarbazine) and programmed for radiotherapy.

To better understand this cancer, we here report the case of a 43-year old patient diagnosed with localized and isolated primary colonic NK/T-cell lymphoma without associated enteropathy, treated wih 3 cycles of AspaMetDex with a poor response who died during treatment with a clinical picture of acute abdomen. Primary intestinal NK/T-cell lymphoma most commonly affects the young subject with poor prognosis. It is difficult to distinguish between intestinal NK/T-cell lymphoma and inflammatory or infectious intestinal disorders because of its non-specific clinical and endoscopic features. The histopathological and immunohistochemical data as well as the study of DNA allow to adjust the diagnosis and to classify this lymphoma according the European Enteropathy type T-cell lymphoma (ETL)., Competing Interests: Les auteurs ne déclarent aucun conflit d’intérêt.
