Media file 4: Axial fast low-angle shot MRI demonstrates decreased signal intensity associated with the brain capillary telangiectasia. This finding is characteristic of capillary telangiectasia, but it is also seen in developmental venous anomalies. The decreased signal intensity is not a result of hemorrhage, but rather, it is from the deoxyhemoglobin in the blood flowing in the malformations.

Axial fast low-angle shot MRI demonstrates decreased signal intensity associated with the brain capillary telangiectasia. This finding is characteristic of capillary telangiectasia, but it is also seen in developmental venous anomalies.

Media file 5: Axial fast low-angle shot gradient-recalled echo MRI obtained through the pons shows a linear area of decreased signal extending from the inferior edge of the malformation (arrows). This finding indicates that the lesion may be a combined capillary telangiectasia and developmental venous anomaly because it has characteristics of both.
