“…Because DVAs are most commonly clinically silent abnormalities, they are often discovered incidentally during brain imaging for other unrelated symptoms. DVAs rarely bleed in isolation, with an incidence of approximately 0.22-0.34% per year [ 3 , 4 ]. Most intracerebral hemorrhages involving DVAs are attributed to associated cerebral cavernous malformations (CCMs) rather than DVAs themselves [ 5 , 6 ].…”

Developmental venous anomalies (DVAs) are clinically benign, low-flow vascular malformations that classically hemorrhage only when associated with a cerebral cavernous malformation. It is very rare for an isolated DVA to hemorrhage. Resection of the DVA is generally contraindicated because of the high risk of venous infarct. We present the case of a large symptomatic hemorrhage stemming from an isolated DVA. The hematoma was evacuated and the hemorrhagic portion of the DVA was resected. This case demonstrates that in rare circumstances, careful resection can successfully treat hemorrhagic DVAs.

“…These thereby translate into venous hypertension-induced focal neurological deficits brought about by spontaneous intracranial hemorrhage, including intraparenchymal, subarachnoid, ve-nous infarcts, outflow obstruction-induced gliosis, tumefactive demyelination, and more. [16][17][18] Through this series, we intend to illustrate the conventional cross-sectional imaging and perfusion abnormalities of DVA and thereby extend the scope in diagnosing the arterialized, transitional, and resistive variants.…”

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.
