  • 1. Short case publication... Version 3.19 | Edited by professor Yasser Metwally | April 2010 Short case Edited by Professor Yasser Metwally Professor of neurology Ain Shams university school of medicine Cairo, Egypt Visit my web site at: http://yassermetwally.com A 26 years old male patient presented with manifestations of increased intracranial pressue. DIAGNOSIS: INTRAVENTRICULAR SUPRATENTORIAL EPENDYMOMA
  • 2. Figure 1. Precontrast CT scan: Intraventricular ependymoma filling the lateral and third ventricle, the lesion shows extensive perivascular calcification. The tumor is a huge one, involving both lateral ventricles and causing extensivehydrocephalus. Figure 2. Postcontrast CT scan: Intraventricular ependymoma filling the lateral and third ventricle, the lesion shows extensive perivascular calcification (Actually perivenous) and is drained by the deep venous system through the vein of galen. Notice the dense homogeneous enhancement. Hydrocephalic changes are seen with possible transependymal edema (A). (C is a bone window of B)
  • 3. Figure 3. Angiography shows the extensive tumour hypervascularity that is mainly drained by the deep venous system through the vein of galen. Figure 4. The tumor has extended to the third ventricle, ? the interhemispheric fissure, and Probably the suprasellar and the quadrigeminal cistern. CSF seedling is probably the cause of dissemination through the basal cisterns and the bihemispheric fissures.
  • 4. Figure 5. Histopathological picture of ependymomas with the characteristic rosettes (The patient's histopathology) The patient's tumor was debulked surgically and histopathological examination revealed an ependymoma of the cellular type with Perivascular pseudorosettes. The patient was given a course of postoperative radiotherapy (Fig. 5). The patient died 7 month following the operation. References 1.
