A 31-year-old overweight man, suffering from high-blood pressure, was hospitalized for transient fits and hemiparesis. MRI disclosed a large irregular mass affecting the vault, meninges and invading the parietal lobe. At neurosurgery, the lesion was necrotic, hemorrhagic and poorly demarcated from the surrounding brain. Histopathology revealed a benign Langerhans cell histiocytosis. No other systemic nor organic lesions could be discovered. After additional local radiotherapy, the patient recovered completely and regained normal activities 6 months later.
