Abstract
Meningeal hemangiopericytomas are rare and account for less than 1% of all central nervous system tumors. Metastatic hemangiopericytoma to the spine from cranial meningeal hemangiopericytomas are much rarer, with five surgically verified reported cases. The authors report a rare case of metastatic hemangiopericytoma to the cervical spine in a 55-year-old female who presented with posterior neck pain and tingling sensation in her left arm. Magnetic resonance imaging(MRI) revealed a large intraspinal and extraspinal mass extending from C6 to T1 and destruction of the C6 and C7 vertebral bodies with compression of the spinal cord. The patient underwent subtotal removal of the extraspinal mass and corpectomy of C6 and C7. Stabilization and reconst- ruction were achieved with an autograft along with Hams cage and anterior cervical plate fixation, followed by subsequent radiotherapy. The tumor was histologically verified as being a metastatic hemangiopericytoma, which was identical to a previous cranial tumor removed 78 months before admission. Metastatic hemangiopericytoma, although extremely rare, should be kept in mind when a patient with adequately treated meningeal hemangiopericytoma presents with back or neck pain or pain accompanied by weakness. Because of the long latency period following primary surgery, patients with meningeal hemangiopericytoma should be followed up closely on a regular basis. Repeated bone scintigraphy and MRI are useful in identifying metastatic hemangiopericytoma to the spine early.
