Abstract:
First reported case of simultaneous occurrence of hemangiopericytomas(HCP) at multiple sites of craniospinal axis in a thirty four year male is presented. Patient presented with neck pain for 1 year, and one episode of simple partial seizure involving his left lower limb. He was diagnosed as having HCP in right middle one third parasagittal region, and C4,5 vertebral bodies. Another lesion was present in L5 vertebra, which was radiologically similar to the cervical lesion, but not biopsy proven. High index of suspicion, and low threshold for screening, for coexistence of spinal HCP, in patients harboring cranial HCP's and complaints of back pain.
