Incomplete 90° intestinal rotation in a clockwise direction results in complete common mesentery being placed in a mirror image to and with a similar appearance to complete common mesentery. This rotation places the colon in the right half of the abdominal cavity and the small intestine in the left half of the abdominal cavity. We report the case of a 19-year-old patient with a history of cerebral palsy secondary to meningitis who presented with melaena and inflammatory anaemia. CT enterography was performed which showed regular, non-stenosing circumferential wall thickening of the sigmoid colon and rectosigmoid junction compatible with Crohn's disease, which was confirmed by pathophysiology. It also revealed transposition of the colon to the right hemi-abdomen and the small intestine to the left hemi-abdomen, the caecum to the right iliac fossa, and the third portion of the duodenum to the left of the mesenteric vessels.
Background: Patellar tendon rupture is a rare condition, especially when it is bilateral. The most frequent associated pathologies are systemic lupus erythematosus, chronic renal failure, or treatments like corticosteroids. The aim of this case report is to draw attention to the non-specific clinical aspect of this condition, to recall its radiological signs, and highlight the diagnostic contribution of musculoskeletal ultrasound. Case presentation: A 39-year-old man was diagnosed with a systemic lupus erythematosus with cutaneous, pulmonary, cardiac, hematological, renal, and immunological manifestations. He was treated with high-dose corticosteroids. Within 3 months he presented with a total functional impotence of the knees. On physical examination, there was a gap in the right infrapatellar region, his patellae were abnormally ascended, and his left knee was swollen. Insall-Salvati ratio on knees conventional radiographies was 2.5 in the right and 2.25 in the left knee, assessing bilateral patella alta. Ultrasound revealed a complete and bilateral patellar tendon rupture. The treatment consisted in a surgical repair and physiotherapy. The patient was able to mobilize independently after 6 months. Conclusions: Bilateral patellar tendon rupture is exceptional. Systemic lupus erythematosus and corticosteroids are among trigger factors. Careful examination of the patellae should be done in front of knee extension deficit. Ultrasound plays a determining role in the diagnosis.
Eccrine porocarcinoma is a rare type of skin neoplasm. It represents less than 0.01% of all epithelial cutaneous tumours. 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
