Intracranial hemorrhage associated with lower grade glioma is unusual. Furthermore, pleomorphic xanthoastrocytoma (PXA) with intracranial hemorrhage, especially in a children, is extremely rare. We report here a rare case of child PXA with intracranial hemorrhage. An 11-year-old girl was admitted with headache and convulsions. A computed tomography scan demonstrated intracranial hemorrhage in the right temporal lobe. An angiogram revealed no vascular disease including arteriovenous malformation, angioma or aneurysm. Magnetic resonance (MR) imaging demonstrated no enhanced or cystic mass to suggest tumor presence. A follow-up study by MR imaging at 6 months after onset of the intracranial hemorrhage revealed a cystic mass lesion, with gadolinium-enhancement, in the right temporal lobe. This mass lesion was removed by surgery and diagnosed as PXA. Areas of tumor lesion could not be diagnosed immediately after the intracranial hemorrhage since bleeding lesion was prominent. Lower grade gliomas, including PXAs, should therefore be taken into consideration in the differential diagnosis of pediatric intracranial hemorrhage cases, separately from vascular disease and/or malignant brain tumor.
