Developmental venous anomalies (DVAs), previously also known as venous angiomas, are variations of normal trans-medullary veins draining from white and gray matter. DVAs are usually asymptomatic and mostly discovered incidentally on brain imaging. However, some studies have reported symptomatic cases associated with DVAs. ⋯ Obstructive hydrocephalus following aqueductal stenosis caused by DVAs is very rare; nonetheless, it can be considered as a causal differential diagnosis for hydrocephalus. Whether ETV should be chosen, as the technique for diversion of cerebrospinal fluid (CSF) flow, remains controversial. This case report showed that ETV was effective and safe.

Arteriovenous malformations (AVMs) are a common cause of intracranial hemorrhage in children, which can result in elevated intracranial pressure (ICP) and cerebral edema. We sought to explore the role of initial decompressive craniectomy at time of rupture, followed by interval surgical AVM resection, compared to treatment with initial resection, in clinical outcomes and recovery in children. ⋯ Children presenting with AVM rupture who require emergent decompression may safely undergo emergent craniectomy with interval AVM resection and cranioplasty without additional risk of morbidity or mortality. This is reasonable in those with elevated intracranial pressure. This strategy may provide time for initial recovery and allow for natural degradation of the hematoma enhancing the plane for interval AVM resection, perhaps improving outcomes.
