title: [Intracranial hypertension as the first clinical manifestation of gliomatosis cerebri].
abstract: A case of gliomatosis cerebri which clinically presented with a syndrome of intracranial hypertension (ICH), involvement of bilateral sixth cranial nerves, and oppressive holocranial headache of one week of evolution. Cranial MR and CT were performed demonstrating diffuse hypodense cortical-subcortical lesions on tomography and in T1 sequences and hyperdense lesions in T2 sequences with irregular contrast enhancement. Intracranial pressure was measured by ventricular catheter with the appearance of high, maintained pressure waves (Lundberg A waves). Ventricular LCR study and cerebral angiography did not provide additional data. Meningeal and cerebral biopsies showed infiltration by pleomorphous glioma leading to the diagnosis of gliomatosis cerebri. The patient was treated with steroids, hyperosmolar agents, external LCR derivation and tumoral radiotherapy. Nonetheless, the patient dies at six months of initiation of the symptoms. Gliomatosis cerebri should be taken into account in the differential diagnosis of clinical pictures presenting with ICH.
