That blood in the subarachnoid space could possibly produce hydrocephalus was first suggested by Bagley in 1928 (3, 4). His conclusions were based on both experimental and clinical studies even though he actually failed to demonstrate a communicating hydrocephalus. ⋯ Recently neurosurgeons have become more aware of this pathological and clinical entity and have reported excellent results in patients treated soon after its recognition (5,9,16). We report a single case of post-subarachnoid haemorrhage hydrocephalus which we feel serves to emphasize the dramatic improvement which can follow treatment of the hydrocephalus.

Case Reports
Arnold-Chiari type II malformation. A clinicopathological study with special reference to its surgical treatment.
We report two cases of Arnold-Chiari type II malformation which died as a result of respiratory arrest due to malfunction of a ventriculo-peritoneal shunt. The autopsy findings are described with special reference to surgical treatment of the condition.

This retrospective investigation of 55 patients, who had been treated with shunts, on account of normal pressure hydrocephalus (NPH) is an evaluation of the results in relation to the type of shunt and the complications developing from it. Sixty per cent of these patients showed an objective improvement after diversion of the CSF, 44 per cent had complications, which were fatal in 9 per cent. The patients who had a primary theco-perintoneal shunt showed a greater amount of improvement and fewer severe complications after the shunt. The successfully treated complications were not incompatible with a post-operative improvement.

A case of intradural hydatid cyst, simulating disc protrusion is described. It is emphasized, that in countries like Greece, the possibility of hydatid cyst compressing the spinal cord, should always be considered.
