Clear Cell Ependymoma of the Temporal Lobe in a Child: A Case Report

Abstract

A 12-year-old boy with a left temporal tumor diagnosed as clear cell ependymoma (CCE) was reported. CCE is an uncommon central variant of ependymomas with a predilection for the supratentorial region in children. Brain tumors with a honeycomb pattern with clear cells having round nuclei and perinuclear halos could pose a problem in the differential diagnosis with the other tumors with clear cells. There were 41 reported cases of CCE in the literature. In 61% of these cases, tumors were located in the supratentorial region, and in the others in the posterior fossa and spinal cord. However, there was none located in the temporal lobe except in the case presented here.

Differentiation of Clear Cell Ependymoma of the Cerebellum From Hemangioblastoma by Thallium-201 Single Photon Emission Computed Tomography -Case Report-

“…[1][2][3][4][5][7][8][9][10][11][12][13][14][16][17][18][19][20][23][24][25][26][27][28] CCE seems to have a predilection for the supratentorial region (supratentorial, 42; infratentorial, 16; spinal, 4) in contrast to the classical subtypes of ependymomas. The recurrence rate of CCE in all locations was about 60% during the follow-up period, [1][2][3][4][5][7][8][9][10][11][12][13][14][16][17][18][19][20][23][24][25][26][27][28] which is higher than other subtypes of ependymoma. 15) The clinical course of CCE was the worst among benign ependymomas, with a significantly higher expression of M...…”
