We report a very rare case of intracranial capillary hemangioma. This 15-year-old girl complained of pulsating headache in the temple area that aggravated with change of body positions. This headache usually lasted for 5 min and resolved without any treatment. Preoperative computed tomography (CT) and magnetic resonance imaging (MRI) strongly suggested cavernous hemangioma in the right deep parietal lobe. She underwent complete resection of the tumor through right parietal craniotomy. Postoperative course was uneventful. Histologic examinations demonstrated a densely grown numerous capillary-like vascular structure with endothelial cells, hemosiderin deposition, and hemorrhage. Intracranial, intra-parenchymal capillary hemangioma is a very rare vascular tumor or tumor like lesions. Only four cases with intracranial, intra-parenchymal capillary hemangioma were reported previously. Differential diagnosis includes other vascular tumors such as cavernous hemangioma, but it is not so easy to differentiate capillary hemangioma from other lesions. Therefore, surgical excision and histologic diagnosis would be important to diagnose it if possible.
