| Abstract |
|
Intracranial tumors presenting in the first year of life are uncommon. Brain tumors in infancy are
predominantly supratentorial, whereas in older children the majority are infratentorial. Malignant
ependymoma is a rare type of primitive ependymal tumor with clinically high malignancy.
We experienced a malignant ependymoma in a 5 month old girl who had progressive enlargement
of head circumference with vomiting. Brain computed tomography revealed a 10 x 10 cm sized mass
in left parietotemporal area of the cerebral hemisphere with multiple punctate calcifications along
the outer margin of the mass. Diagnosis was confirmed by histologic examination of the tumor tissue
On microscopic examination the tumor was well circumscribed and fairly cellular. The tumor cells
were polygonal or elongated with regular round nuclei and delicate chromatin pattern. In areas
perivascular pseudorosette as well as numerous mitoses and multifocal necrosis were presented.
We present a case of malignant ependymoma with the brief review of related literatures. |
