Developmental venous anomaly

Case contributed by A.Prof Frank Gaillard

Presentation

Flashing lights and headache FI.

Patient Data

Age: 80 years
Gender: Male
Modality: CT
Prominent vessles draining to the superior sagittal sinus are noted in the right frontal lobe, wihtout a convincing nidus. 

MRI brain

Modality: MRI

Within the right frontal lobe are 2 prominent vascular structures which form a result of the confluence of a number of smaller vessels in drain superiorly, and anteriorly into the superior sagittal sinus. On MRA there is no arterialised flow, no enlargement of the anterior circulation vessels. No nidus can be identified, and no evidence of previous haemorrhage. These are characteristic of developmental venous anomalies and do not represent arteriovenous malformation.

The remainder of the brain is unremarkable in appearance, with no other vascular malformations identified.

Case Discussion
