Sellar hemangiopericytoma. A case report

Primary central nervous system hemangiopericytoma is rare, accounting for less than 1% of primary central nervous system tumors. Diagnosis is histological. Treatment is surgical excision, followed by radiotherapy. Long-term follow-up is mandatory for these tumors with a high potential for recurrence and metastasis. The sellar location is very rare, and can be confused with pituitary adenoma. We report the case of a patient presenting a sellar hemangiopericytoma, who underwent surgery via a transsphenoidal approach, then right frontal craniotomy followed by radiotherapy. There was no recurrence at one year follow-up. © Masson, 2006.
