Spinal arteriovenous malformation with a calcified nodule: illustrative case.

ABSTRACT

BACKGROUND: This article describes a rare case of cervical spinal arteriovenous malformation (AVM) mimicking a neurogenic spinal tumor. OBSERVATIONS A 22-year-old female presenting with a C6-7 AVM with a calcification nodule experienced new-onset acute right upper radiculopathy associated with extradural compression of the spinal cord. Note that spinal AVMs with a calcified nodule are rare. Endovascular embolization is generally used to relieve the symptoms of AVM; however, this procedure cannot relieve cord compression, particularly in cases complicated by calcified nodules. This article discusses treatment options. LESSONS Decompression surgery is preferable to endovascular embolization because it alleviates symptoms while preventing cord compression and minimizing the risk of recurrence.
