Abstract

OBJECTIVE: Astroblastomas are rare glial neoplasms that usually occur in young adults and have a predilection for the cerebral hemispheres. Patients typically present with signs of increased intracranial pressure and seizures. Imaging studies reveal circumscribed, contrast-enhancing tumors that contain both cystic and solid components with variable peritumoral edema. Hemorrhage, which suggested the presence of a vascular lesion in this patient, has not been previously described as a feature of this neoplasm. CLINICAL PRESENTATION: The authors report the case of a 33-year-old woman who presented with spontaneous intraparenchymal hemorrhage. The collective radiographic data suggested the presence of a cavernous malformation. INTERVENTION: A right frontotemporal craniotomy was performed under frameless stereotactic image guidance. An astroblastoma was diagnosed after resection and neuropathological examination. CONCLUSION: A rare radiological to pathological correlation of astroblastoma is presented in which the evolving hematoma, as observed on magnetic resonance imaging scans, complicated the radiographic diagnosis of this lesion. The clinical, radiographic, and pathological features of astroblastomas, as well as the natural history of these rare glial neoplasms, are reviewed. This case illustrates the capacity of astroblastomas to hemorrhage, disguising the classic radiographic findings typical of this glial neoplasm.
