Presentation
Known developmental venous anomaly.
Patient Data
Right frontal developmental venous anomaly draining in the superior sagittal sinus.
There is an area of signal abnormality in the anterior aspect of the right corona radiata with no mass effect. It is slightly hyperintense on T2 weighted images, low signal on SWI and demonstrates stippled enhancement after contrast administration.
Case Discussion
Although it is an unusual location, the lesion is consistent with capillary telangiectasia. The most common location is the brainstem, especially the pons. They are known as an “angiographically occult vascular malformation". Most of the lesions are asymptomatic.
