Extraventricular cerebral anaplastic ependymomas

Surgical Neurology, 1999
Anaplastic ependymomas are considered to be uncommon cerebral tumors by most authors. We have had the opportunity to study 34 cases of such lesions in 13 years.34 cases of anaplastic ependymoma operated in different hospitals of Maracaibo, Venezuela, during the period of 1983-1995 were analyzed.

Anaplastic ependymoma with pleuropulmonary relapse

Medical and Pediatric Oncology, 2003
A 15-year-old white adolescent was first diagnosed with a right temporo-parietal anaplastic ependymoma at the age of 8 years. A tumor of 7 3 4 cm-size was macroscopically completely resected and adjuvant chemotherapy was applied (Fig. 1). Within the next 31⁄2 years, he suffered from three local relapses.

Ectopic cervical anaplastic ependymoma

Pathology International, 2005
Ependymomas generally arise in the central nervous system (CNS), although rare primary extraneural ependymomas have been observed. Reported herein for the first time is the case of a patient with primary ectopic cervical anaplastic ependymoma. The tumor was found in the right neck root region of a 35‐year‐old man.

Anaplastic ependymoma with sclerotic bone metastases

Pediatric Blood & Cancer, 2010
Ependymomas are glial central nervous system (CNS) tumors that arise from the ependymal layer of brain and spinal cord. These are heterogeneous group of tumors with varied histopathological features and prognosis. They frequently relapse at the primary site and may disseminate to other CNS sites. Extraneural metastases are, however, extremely rare.

A case of an anaplastic ependymoma with gliosarcomatous components

Brain Tumor Pathology, 2009
A 29-year-old woman presented with a severe headache. Computed tomography revealed a large cystic lesion with a mural nodule-like mass homogeneously enhanced with contrast medium in the right cerebellum. The tumor was removed, and pathological studies revealed a cerebellar astrocytoma corresponding to World Health Organization grade II. When she was 35

Anaplastic ependymoma with ependymoblastic multilayered rosettes

Human Pathology, 2013
Anaplastic ependymoma, World Health Organization grade III, is a malignant glioma with ependymal differentiation characterized by high mitotic activity often accompanied by microvascular proliferation and necrosis, where, generally, much fewer ependymal rosettes are found than in ependymoma, World Health Organization grade II.
