A case of medullary venous malformations with an arterial component coexisting with arteriovenous malformations

N Tomura et al. Surg Neurol. 1990 Jan.

Abstract

We present a rare case of medullary venous malformations with an arterial component coexisting with two small arteriovenous malformations in the same area. The onset was abrupt with subcortical hematoma due to the rupture of one arteriovenous malformation in the frontal area. Single photon emission computed tomography using 99mTc-hexamethylpropyleneamine oxime showed a high-uptake area around the hematoma suggesting increased blood flow. Two types of vascular malformation coexisting in the same area support a theory of congenital malformation originating in intrauterine life.
