A 38-year-old woman suffering from systemic lupus erythematosus was treated with cyclophosphamide and prednisone. Two months later she developed mononeuritis multiplex. After one year, she showed a personality change with aggressiveness and paranoid delusions. Grand mal epileptic fits began to occur. An unenhanced CT-scan showed extensive and bilateral frontal hypodense lesions originally ascribed to vasculitis-caused infarcts. On autopsy, a primary intracerebral lymphoma with extensive necroses was demonstrated. The relationship between SLE, immunosuppressive treatment and primary intracerebral lymphoma is discussed.

An 18-year-old boy with refractory epilepsy and aggressiveness associated to a hypothalamic hamartoma was submitted to a stereotactically guided lesion by thermocoagulation. The target was based on magnetic resonance (MR) images merged with computed tomography scan images taken on the day of surgery while patient was on a stereotactic frame. In order to reveal structures not discernible in MR images, the Schaltenbrand digital brain atlas was merged onto the patient's images. Target and trajectory of the depth electrode were chosen based on three-dimensional imaging reconstructions. A surgical plan was devised to disconnect the hypothalamic hamartoma from the hypothalamus, medial forebrain bundle, fasciculus princeps, and dorsal longitudinal fasciculus. Our target was placed at the inferior portion of the posterolateral component of the hamartoma, bordering the normal hypothalamus. The patient evolved with marked lessening of aggressiveness. Seizure frequency was reduced from several seizures per day to less than one tonic-clonic seizure during sleep per month and only two episodes suggestive of partial complex seizures during daytime. These results have remained consistent over a 24-month postoperative follow-up. Functional neuroanatomy of hypothalamic connections involved in seizure propagation and aggressive behavior was reviewed.
