Magnetic resonance imaging (MRI) of the orbits occasionally demonstrates retinal detachment (RD); this may be as an incidental finding, as a separate entity related to orbital pathology with differing local causes, or as a part of other congenital systemic or metabolic diseases. One congenital ocular disease which could be misdiagnosed as RD is persistent hyperplastic primary vitreous (PHPV), which itself can be associated with RD. MRI scanning features of retinal detachment and associated causes can assist in differentiating both entities effectively, allowing the radiologist to reach the proper conclusions with resultant benefits in subsequent management.
A rare case of renal transitional cell carcinoma (TCC) associated with bland thrombus of the renal vein extending into the inferior vena cava is described. Tumour thrombus in renal cell carcinoma is frequently encountered, but only very rarely occurs with TCC. Bland renal vein thrombosis occurring with renal TCC has not been described before. Contrast enhanced computed tomography assisted in distinguishing between bland and tumour thrombosis and aided in surgical management.
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.
