Imaging intracranial hemorrhage – Case 4 – Arteriovenous malformation – AVM 

This patient has a cerebellar hemorrhage. On CT angiography, there is an enhancing mass of vessels right along the tentorium which is suspicious for an underlying AVM. Conventional angiography confirms the abnormality.

AVMs are graded by their size, involvement of eloquent cortex, and venous drainage using the Spetzler-Martin grading scale. This gives a measure of operative mortality from removing the lesion and helps guide management.

The level of this lecture is appropriate for medical students, junior residents, and trainees in other specialties who have an interest in neuroradiology or may see patients with intracranial hemorrhage or stroke.
