[Intracranial septic aneurysm in an infant. Apropos of a case and review of the literature].

This case report describes a four and a half month old infant with all meningitis symptoms and a sub arachnoidal hemorrhage at the lumbar puncture. Transfontanelle - ultrasonography and computed tomography enables us to diagnose a right intra-cerebral hematoma. Angiography visualises a mycotic aneurysm in a distal portion of the sylvian artery. A success is obtained both by neuro surgery and antibiotics treatment. Regarding this case of intra cranial septic aneurysm and the ones reviewed in the literature, aetiology, frequency, clinical features and management are discussed by the authors.
