, clear cell ependymoma, and PA with oligodendroglial-like cells are possible diagnostic challenges in small biopsies.
One case of central neurocytoma
was reported on FS as a low-grade glioma favoring ependymoma [Figure 4 a and b].
The relatively avascular nature of subependymomas also helps distinguish them from other tumors such as central neurocytomas
Abstract: Central neurocytoma
(CN) is a rare intraventricular brain tumor that affects young adults.
HPE Showing Homogenous Cells Separated by Delicate Vascular Stroma with Uniform Round Nuclei in Central Neurocytoma
(CN) is a primary neoplasm of the central nervous system that was first introduced as a distinct entity by Hassoun et al (1) in 1982.
Contrast enhanced Magnetic Resonance Imaging (MRI), was performed which revealed features suggestive of intraventricular neurocytoma
with intraventricular hemorrhage (Figs.
Challenging diagnosis: oligodendroglioma versus extraventricular neurocytoma
In females majority (9) of the patients had glioma followed by 5 patients each had pituitary adenoma and metastasis; 4 patients had meningioma, 2 patients had central neurocytoma
and one each had pineal region tumour and benign cystic lesions.
The individual tumor cells are morphologically similar to the prototypical neurocytic tumor of the central nervous system, the central neurocytoma
The differential considerations for both studies included ependymoma, subependymoma, neurocytoma
, giant cell astrocytoma, and metastasis.
