Three male patients with posturally induced, intermittent hydrocephalus were found on pneumoencephalography to have cavum septi pellucidi and cavum vergae. The clinical presentation resembled that of colloid cyst of the third ventricle. Remission followed excision of the septal walls in 2 cases, but relapse of symptoms occurred when the caves reformed. It is postulated that intermittent obstruction to the lateral ventricular outflow by the cavum septum pellucidum and cavum vergae was the basis of the symptomatology. Transcaval shunting may prove to be the simplest reliable form of treatment.
Meningiomas are frequently amenable to total resection. On review of a 10-year series of these tumours in Western Australia it was found that 18 out of total 78 were undiagnosed during life. Analysis of the present series is undertaken as well as comparison with other series in the literature in respect of the overall clinical picture. It is suggested that, in cases of gradual psychological deterioration, the presence of a benign intracranial space-occupying lesion ought to be excluded.
A series of gliomas is reviewed in an endeavour to establish the efficacy or otherwise of the various forms of treatment available. In general, it would seem that prognosis depends upon the activity of tumour cells and the anatomical relationships of the lesion. From the experience of this series it appears that wide resection, if this is possible, offers a longer survival time than any other form of treatment.
