title: Recurrent sterile meningitis caused by a pituitary abscess.
abstract: The case of a 21 year old woman who presented with recurrent sterile meningitis and bitemporal hemianopia is described. Computed tomographic scan showed a large low density ring enhancing lesion above and within the pituitary fossa which at operation and on histological examination was found to be compatible with an abscess. The visual field defect recovered completely and the scan appearances returned to normal postoperatively.
