Intradural spinal arteriovenous malformation of the glomus type: a case report.

: Spinal arteriovenous malformations (AVMs) being even rarer than cranial ones, constitute 3 - 4% of all spinal tumours, with an overall male:female ratio of 4:1. We report the case of a 24-year old female Youth Corps member who presented with an apoplectic onset of a left hemiparesis, progressively deteriorating to an incomplete quadriplegia with motor power of 2 and 0 in the right and left lower limb muscle groups, respectively. Magnetic resonance imaging (MRI) showed a vascular malformation whose precise nature was indeterminate; the definitive diagnosis of a Glomus AVM was only made intra-operatively. Laminectomy with complete surgical excision was done and she gradually improved to ambulate with minimal support. The experience in our unit tends to support the observation in literature that spinal arteriovenous malformations could be very rare, and depending on the location, could be amenable to complete surgical excision and recovery of neurological function.
