Intradural Hemangiopericytoma of the Lumbar Spine: Case Report

Imaging features of central nervous system haemangiopericytomas

“…4 and 5). A literature review of 34 cases showed the majority of spinal lesions to be at the thoracic and cervical levels, and favouring extradural over intradural sites [12] (Fig. 4).…”

Intradural Extramedullary Hemangiopericytoma of the Thoracic Spine Infiltrating a Nerve Root

“…The preoperative working diagnosis was meningioma or schwannoma. At histopathology, an eight intradural cases were reported previously, 13,17,20,26,28,36 including only three cases involving a nerve root. Only one case, reported by Kashiwazaki et al , 26 was a case of subpial hemangiopericytoma.…”

“…9 Hemangiopericytoma rarely occurs in the spine, with only 64 cases reported previously, 3 , 7 , 10 -42 of which eight were intradural ( Table 1 ). 13,17,20,26,28,36 We present a case of spinal intradural extramedullary hemangiopericytoma that was completely subpial, with apparent infi ltration of a nerve root. pain radiating to the left leg and progressive paraparesis.…”

Unusual primary intradural and extradural thoracic spinal hemangiopericytoma: Radiological, diagnostic and therapeutic dilemmas

“…Of the 39 cases reported, only 6 have been intradural. [2,3] We report an extremely rare case of a mid-thoracic primary spinal hemangiopericytoma with both intradural and extradural components without an obvious dural breech. This probably the first report of such a presentation of a spinal hemangiopericytoma.…”

“…Histopathology examination revealed a typical appearance of a hemangiopericytoma on H and E staining and immunohistochemistry [ Figure 3]. The patient has received adjuvant There have been reports of extradural hemangiopericytomas arising primarily from bone and of others that arise from dura and invade the extradural space [3] and others invading adjacent anatomical spaces; sub-pial to subdural [4] and from subdural to intramedullary. [5] Of these six patients only one has been reported to occur in the thoracic spine.…”
