Objective Symptomatic developmental venous anomalies (DVAs) are rare. Here, we illustrate the varied clinicoradiologic profiles of symptomatic DVAs and contemplate the mechanisms that render these (allegedly) benign entities symptomatic supported by a review of literature. Methods Institutional databases were searched to identify cases of symptomatic DVAs. Clinical and imaging (angiographic and cross-sectional) data of 9 cases with 11 neurovascular symptoms consequent to inflow/outflow perturbations and mechanical obstruction that manifested because of the strategic topography of underlying DVAs were analyzed. A review of the existing literature on DVAs in agreement with our case series was performed on publications retrieved from the PubMed database. Results Symptoms secondary to venous hypertension arising from flow-related perturbations were broadly divided into those arising from restricted outflow and increased inflow. Restricted outflow occurred because of collector vein stenosis (n = 2) and collector vein/DVA thrombosis (n = 3), whereas the latter pathomechanism was initiated by arterialized/transitional DVAs (n = 2). A mechanical/obstructive pathomechanism culminating in moderate supratentorial ventriculomegaly was noted in 1 case. One patient was given a diagnosis of hemorrhage associated with a cavernoma. Conclusions Awareness and contextualization of potential flow-related perturbations and mechanical insults that render DVAs symptomatic aid in accurate diagnosis, management, and prognostication.

Colorectal cancers are more common in the West than in Asian subcontinent. An increasing trend in the occurrence of colorectal signet cell carcinomas has been observed, exhibiting association with inflammatory bowel disease. Its distinct clinical features, pathognomonic, histologic, and radiologic appearance make it an unmissable entity. We report two such cases in the background of inflammatory bowel disease. We aim to familiarize our readers with its cross-sectional imaging features.

Cryptococcosis is an invasive systemic mycosis caused by Cryptococcus, a genus of yeast. Causative organisms for human cryptococcosis include Cryptococcus neoformans and Cryptococcus gattii. Disease due to C.neoformans is conventionally seen in patients with underlying immunosuppression, whereas C.gattiirelated infection is usually seen in immunocompetent people. The fact that the infection can occur among otherwise healthy individuals underscores the importance of having a necessary understanding of the pathophysiology and clinical and radiological presentations of the disease. We report a case of disseminated pulmonary and central nervous system (CNS) cryptococcosis in an apparently immunocompetent individual with unusual radiological findings necessitating probing for alternative diagnoses. We have attempted to supplement and revise the existing data on the radiological manifestations of C.gattii.
