A 23 year old Asian female presented with swelling of right knee joint for 5 years with history of exacerbations and remissions of symptoms. She was initially diagnosed as a case of suprapatellar bursitis based on clinical and X-ray findings. Further evaluation with higher imaging modalities was pathognomonic of lipoma arborescens. Patient underwent synovectomy and the diagnosis was confirmed histologically. We describe a histologically proven case of lipoma arborescens to highlight the imaging findings on X-ray, Ultrasound and Magnetic resonance imaging with arthroscopic correlation. The unique feature of this case report is multimodality imaging correlation with arthroscopy and histopathology findings. We have highlighted the pathognomonic imaging findings of this rare but benign intra-articular lesion and also discussed the differential diagnosis in detail.
The Chiari Malformation is a neural tube defect involving the posterior cranial fossa and the hind brain, characterized by herniation of the posterior fossa contents below the level of the foramen magnum. Four types were described by Hans Chiari in the late 19th century. Of these, Type III is exceedingly rare. We report the case of Chiari III malformation in a 24-week fetus by the integration of radiologic and autopsy findings which was conspicuous by the absence of high cervical spina bifida and the presence of occipital squama defect.
A 4-year-old girl presented with non-bilious vomiting and loss of appetite and weight. At laparotomy, a non-communicating pyloroduodenal duplication cyst was present. Subtotal excision of the cyst and cauterization of the mucosal lining of the common wall was performed. The post-operative recovery was uneventful.
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.
