Abstract:
This study was carried out on 36 patients (the youngest was 2 years old and the oldest was 64 years old) with tumors located in the 4th ventricle, which were admitted to Cho Ray Hospital in 2002. Results: meduloblastomas was the most common tumors (58.3%), following ependymomas (19.4%) and astrocytomas (11.1%). Some type of tumors were rare: hemangioblastomas (5.6%), meningioma (2.8%), and lymphoma (2.8%). The median duration of symptoms from the onset to diagnosis was 8 weeks. Most of patients experienced intra-cranial hypertension syndrome (97.2%), and cerebellar syndrome (77.8%). On the brain CT scan images, the different characteristics of tumors including calcifications, hemorrhage, cyst-necrosis, density and contrast enhancements were useful in making differential diagnosis. The rate of lateral and the 3rd ventricular dilatations were very high (94.4%) because tumors quickly blocked flow of cerebrospinal fluid
