Abstract Twenty patients with triventricular hydrocephalus due to pineal region tumors constituted the subject of this study. These cases were subjected to endoscopic third ventriculostomy and biopsy at the Department of Neurosurgery; Tanta University Hospital from January 2009 up to May 2015. Sixteen patients were males (80%) and four were females (20%). All patients were subjected to thorough clinical examination, neuroimaging and routine laboratory investigations. Large group of patients (25%) were in the first decade of life. No ETV procedures were performed below 6 months age. Headache was the most common clinical presentation in this study (85%), followed by blurring of vision, vomiting and unsteady gait. MRI was essentially performed to all the cases of the study both pre and postoperatively to assess the type and cause of hydrocephalus, and any radiological evidence of improvement of hydrocephalus such as reduction in the ventricular size, resolution of trans ependymal CSF permeation, and widening of the subarachnoid space. Triventricular hydrocephalus was a constant radiological finding present in all cases of the study. Obliterated subarachnoid space was found in 65% of cases, trans ependymal permeation (65%), and bulging floor of 3rd ventricle in 45% of cases followed by wide prepontine cistern (10% of cases) Tumor size was in the range between 1.5 -3 cm in 65% of cases. |
