ABSTRACT
Several, but not many, cases of congenital meningeal hemangiopericytoma have been described to date. Herein, a case of meningeal hemangiopericytoma in a newborn is described. The patient was a 2-week-old boy with expanded fontanelles and frequent vomiting. A 5 cm sized mass was found in the left temporo-parietal lobe, which was well circumscribed and lobulated. Histologically the tumor was compatible with anaplastic (malignant) hemangiopericytoma, which showed pleomorphic nuclei, frequent mitotic figures and extensive hemorrhagic necrosis. The tumor cells were immunoreactive for vimentin, but negative for CD34, desmin and S-100 protein. Differential diagnosis for meningeal hemangiopericytoma was discussed, and the fact that meningeal hemangiopericytoma might have occurred congenitally was emphasized.
