“…In our case, SWI depicted an old hemorrhage in the right basal ganglia, presumably due to the DVA, but it was fortunately asymptomatic. Similar to the cases reported by Xian et al [24] and Isikbay et al [25] , the DVA of our patient coursed ventrodorsally across the orifice of the aqueduct before draining into the vein of Galen. The duration of the symptom in our case was extremely short because the previous detection of ventriculomegaly led to a quick diagnosis based on MRI, including SWI and postcontrast T1WI.…”

“…5 However, obstructive hydrocephalus secondary to physical obstruction of DVAs is rare, and only 16 cases have been reported in the existing literature (Table 1). [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Previously reported cases involved infants and older individuals (age range, 0-83 years), and the most common symptom was headache which was associated with increased intracranial pressure. The patients presented with headaches in 11 of the 16 cases.…”

BACKGROUND Developmental venous anomalies (DVAs) are congenital anatomical variants of the normal deep parenchymal veins. DVAs are occasionally found incidentally on brain imaging, and most cases are asymptomatic. However, they rarely cause central nervous disorders. Herein, a case of mesencephalic DVA that caused aqueduct stenosis and hydrocephalus and discuss its diagnosis and treatment is reported. OBSERVATIONS The patient was a 48-year-old female who presented with depression. Computed tomography and magnetic resonance imaging (MRI) of the head revealed obstructive hydrocephalus. Contrast-enhanced MRI revealed an abnormally distended linear region with enhancement on the top of the cerebral aqueduct, which was confirmed as a DVA by digital subtraction angiography. An endoscopic third ventriculostomy (ETV) was performed to improve the patient’s symptoms. Intraoperative endoscopic imaging showed obstruction of the cerebral aqueduct by the DVA. LESSONS This report describes a rare case of obstructive hydrocephalus caused by DVA. It highlights the usefulness of contrast-enhanced MRI for diagnosing cerebral aqueduct obstructions due to DVAs and the effectiveness of ETV as a treatment option.

Developmental venous anomalies (DVAs) are the most common slow-flow venous malformation in the brain. Most DVAs are benign. Uncommonly, DVAs can become symptomatic, leading to a variety of different pathologies. DVAs can vary significantly in size, location, and angioarchitecture, and imaging evaluation of symptomatic developmental venous anomalies requires a systematic approach. In this review, we aimed to provide neuroradiologists with a succinct overview of the genetics and categorization of symptomatic DVAs based on the pathogenesis, which forms the foundation for a tailored neuroimaging approach to assist in diagnosis and management.ABBREVIATIONS: BRBNS ¼ blue rubber bleb nevus syndrome; CCM ¼ cerebral cavernous malformation; CMMRD ¼ constitutional mismatch repair deficiency syndrome; CVMS ¼ cerebrofacial venous metameric syndrome; DVA ¼ developmental venous anomaly; WMH ¼ white matter hyperintensities D evelopmental venous anomaly (DVA) is an extreme varia-
