Primary calvarial hemagioma presenting as chronic subdural hematoma

Abstract

Primary intra-osseous cavernous hemangiomas (PICHs) represent slow-growing benign vascular malformations, most frequently found in parietal and frontal bones and account for ~0.2% of all bone tumors and 10% of benign skull tumors. We report a case of 70-year-old gentleman presented with progressive headache involving left frontal region, aggravated on coughing of five months duration. Radiological features were suggestive of left frontal calvarial lesion and left fronto-parietal chronic subdural hematoma. Histopathology of the calvarial lesion was suggestive of cavernous hemangioma. Meticulous radiological and clinical investigation is essential to rule out all other possible lesions; histopathology confirms the diagnoses, and the preferred treatment is complete tumor removal and management of the associated lesions (i.e., chronic subdural hematoma in present case).
