title: Cerebellar pial arteriovenous malformations presenting with medullary venous hypertension: imaging and endovascular treatment.
abstract: A patient in their 60s presented with headache and progressive lower extremity weakness over 1 week. Initial MRI was thought to represent venous hypertension secondary to a dural arteriovenous fistula. However, angiography revealed a cerebellar pial arteriovenous malformation with medullary venous hypertension. The imaging and endovascular treatment of this unusual case of a pial cerebellar arteriovenous malformation presenting in that manner is presented.
