“…Computed tomography may not be helpful in the diagnosis, and MRI has proven to be the most sensitive means of both detecting the aqueductal stenosis and evaluating its cause, whether congenital, neoplastic or vascular [9]. Cine MRI provides invaluable information about the dynamic CSF flow through the Sylvian aqueduct [9].…”

“…Therefore, interventional or surgical therapy in such lesions is not warranted regardless of the deep or superficial location [13,14]. These centrally lying lesions cannot be cured by surgery as well, and the only treatment option may be mere shunting of the hydrocephalus [9].…”

“…The preferred term is "developmental venous anomaly" (DVA) [9]. Currently, DVAs are believed to represent nonpathological variations of venous drainage, and the most popular theories of etiology include primary dysplasia of capillaries and small transcerebral veins [10] or a compensatory mechanism when normal venous pathways are bypassed due to accidental thrombosis in the intrauterine period [11].…”

“…Because of their superficial location and tendency to drain into the dural sinuses or Sylvian veins, vascular malformations rarely cause ventricular obstruction, unless complicated with hemorrhage [7]. However, occasional central venous lesions that are occurring in the midline may cause unilateral or bilateral ventricular obstruction [2,8,9]. Up to date, only six cases of aqueductal stenosis caused by DVA have been reported [5].…”

An unusual cause of hydrocephalus: aqueductal developmental venous anomaly

Vascular malformations are infrequent causes of aqueductal stenoses, developmental venous anomaly (DVA) being the rarest among them. DVAs, also known as venous angiomas, are congenital in origin and characterized by dilatation of vessels in the superficial and deep venous system. Although they are usually clinically silent, they can be complicated by hemorrhage, seizures and neurologic deficits. Herein, we report MR imaging findings of a 7-year-old girl whose hydrocephalus was due to an abnormal vein coursing through the aqueduct.

Objective Cerebral developmental venous anomalies (DVAs) are frequent and rarely symptomatic. When symptomatic, DVAs may present with seizures; however, little is known about the characteristics of DVA‐related epilepsy. In this systematic review, we aim to describe the clinical and paraclinical features of patients with DVA‐related epilepsy. Methods This review was registered on PROSPERO (CRD42021218711). We searched the MEDLINE/PubMed and Scopus databases for case reports/series on patients with DVAs complicated by seizures. Studies describing patients with a potentially epileptogenic comorbid lesion close to their seizure focus were excluded. Descriptive statistical analyses were performed to synthetize patient characteristics. The methodological quality of each study was evaluated using a standardized appraisal tool. Results In total, 66 patients were included from 39 articles. The frontal lobe was the most common location for DVAs. The superior sagittal sinus drained half of the DVAs. Seizures were inaugural in most cases, and the most common manifestations accompanying seizures were headaches. EEG was abnormal in 93% of cases, but only 26% had characteristic epileptic spikes. More than half the patients suffered a medical complication due to their DVA, with hemorrhage and thrombosis being the most common. Refractory seizures were encountered in 19% of individuals. At 12 months of follow‐up, 75% of patients were seizure free. Most included studies were at low risk of bias. Significance Epilepsy can be a complication of DVAs; these DVAs are mostly frontal or parietal, draining via the superior sagittal sinus or the vein of Galen.
