A case of primary orbital hemangiopericytoma is reported in a 31-year-old female presenting with progressive proptosis of the left eye and deteriorating diplopia over a period of 2 years. Orbital computed tomography revealed a superiorly located well-circumscribed extraconal mass. A 32x57x16 mm soft mass that appeared grossly encapsulated was removed intact via anterior orbitotomy. Histopathological examination disclosed it to be a hemangiopericytoma. The clinical importance is its potentially malignant behavior, with a high local recurrence rate in case of incomplete excision. Literature was reviewed.
