Abstract:
Study on 73 fourth ventricle tumors that were operated at Cho Ray hospital, from May 2000 to October 2003. The results: tumors were seen in both children and adults, in male more than female at the ages ranging from 2 years old to 64 years old. The most common age group were 1-10 years (52%), then 11-20 years old (21.9%). In fourth ventricle tumors, the median duration of symptoms prior to radiological diagnosis was 6 weeks. The patients experienced symptoms such as headache, vomitting, vertigo. The common syndromes were: raised intracranial pressure syndrome, cerebellar syndrome, pyramidal syndrome and epilepsy. Brain CT scan, absence of cysts and calcifications, homogeneous hyperdensity favor the diagnosis of medulloblastoma. Ependymomas were typically nonhomogeneous hyperdensity, calcified. Astrocytomas showed nonhomogenous hyperdensity and minimal calcification. Most of cases had ventricular dilatation
