ABSTRACT
Spinal meningiomas are much more common in women. The peak age incidence of presentation occurs in the sixth decade. Cystic meningiomas are rare and seem to have a predilection for children. We report a case of cystic spinal meningioma in a young man presenting as a ring enhancing lesion on Magnetic Resonance Imaging (MRI). This case is unusual because of the atypical features of the tumour, the relatively young age and sex of the patient.

The aim of this study is to find out the correlation of the ventricular size of the brain, as it is estimated using brain computed tomography (CT) scan indexes in patients with normal pressure hydrocephalus (NPH), to: a) the clinical symptoms, and b) the results of cerebrospinal fluid (CSF) shunting procedures. We looked for any predictive value in the estimation of brain CT scan indexes, in patients as above, in whom a shunt is going to be placed. It is well known that it is very difficult to decide who is going to improve after shunting. We studied 40 cases of patients with the diagnosis "NPH" in whom the ventricular shunts were placed. Every symptom (motor disturbance, deficit of memory, incontinence) was separately evaluated preoperatively. The outcome of shunting was also evaluated and the patients were graded. The following CT scan indexes were estimated from the preoperative CT scans of the brain in every case: the ventricle-brain ratio (VBR), the bi-caudate and bi-frontal ratios, the third ventricle-Sylvian fissure (3V-SF) ratio, and the four largest cortical gyri. The method we have used for statistics is "one way analysis of variance", correlating the CT scan indexes to the symptoms of the patients preoperatively, and the outcome of them postoperatively. The main conclusion is that the size of the lateral ventricles of the brain preoperatively is not correlated to the outcome after CSF shunting surgery, but it is correlated to the symptoms of NPH preoperatively.

The role of radiation in the induction of central nervous system tumours has repeatedly been documented. Meningiomas induced by low doses of cranial irradiation have been described in many series of cases, but meningiomas induced by high doses of irradiation have still been reported in a limited number of cases. We report the case of a 25-year-old man who presented multiple meningiomas and who had received therapeutic dose of irradiation for a 4th ventricle ependymoma when he was 8 years old.
