1. Abstract
Developmental venous anomalies (DVAs) are widely deemed as anatomic variants of normal venous drainage with low hemorrhage risk. Hence, DVAs are deemed as benign and conservative management of DVA is strongly preferred. For the patients requiring surgical intervention, operation should focus on resection of the hematoma or cavernous angioma, with the DVAs protected. However, DVAs are associated with potential weaknesses due to their angioarchitectural characteristics. A case of DVA patient was followed and analysed. The present case illustrates catastrophic hemorrhagic venous infarct of DVA with obstructive venous drainage, and, to some extent, argues against the assumption that DVA is benign in nature. As a result, we propose that patients with "symptomatic" DVA should undergo MRI and DSA to exclude underlying pathology and clarify the specific structure of DVA, identifying the risk factors that might need intervention in advance, and the final treatment choice should be based on the specific characteristics of different DVA lesions.
