✓ A dural mesenchymal chondrosarcoma is reported in a 19-year-old man. This tumor had features of angioblastic meningioma (meningeal hemangiopericytoma), by light microscopy. However, ultrastructurally this tumor could be distinguished from angioblastic meningioma, and its similarity to extracranial mesenchymal chondrosarcoma was confirmed.

Abstract OBJECTIVE To specify that postoperative radiotherapy is useful for preventing local recurrence and neuraxis recurrence of surgically treated meningeal hemangiopericytomas. METHODS We retrospectively studied 21 patients with meningeal hemangiopericytoma who were followed in our department during a 34-year period. In 17 patients, the meningeal hemangiopericytoma was intracranial, and in 4 there was an intradural extramedullary localization. These groups were studied separately. RESULTS Of the 17 patients with intracranial hemangiopericytoma, all underwent surgery; 8 also underwent radiotherapy (5000–6400 rads) (Group I), and 9 did not (Group II). The mortality rate was zero for Group I patients and 55% for Group II. The mean local recurrence rate was 52% (12.5% in Group I and 88% in Group II; P < 0.05). Neuraxis recurrences occurred in two patients in Group II, and none occurred in Group I (P = 0.4). Peripheral metastasis took place in two patients (22%) in Group II and in one patient (12.5%) in Group I (P = 0.5). Of the four patients with intradural extramedullary hemangiopericytoma, all underwent surgery. Two patients received 4000 rads of radiotherapy after intervention. No patient in this group had a recurrence. CONCLUSION For patients with intracranial meningeal hemangiopericytoma, surgical removal followed by external radiotherapy reduced the risk of local recurrence. It was not demonstrated that postoperative radiotherapy protected against neuraxis metastasis. Radiotherapy did not protect against peripheral metastasis, which can occur up to several years after the first operation. It appears that radiotherapy after surgery for local or neuraxis recurrence did not avoid further recurrence. Radiosurgery is indicated for recurrent tumors measuring less than 25 mm in greatest diameter. For intradural extramedullary localizations, the value of postoperative radiotherapy is more questionable.
