Parker DR. Neuroradiology case of the day. (Courtesy of Amirsys, Salt Lake City, Utah.) Intraventricular tumor with imaging features favoring a central neurocytoma (somewhat atypical in a patient of this age) or subependymoma. Familial multiple cavernous malformation, caused by mutation in Krev interaction trapped protein 1 gene (KRIT-1) The distinct radiological features such as: (1) diffuse and diverse calcifications on CT images; (2) clusters of cysts of varying sizes resulting in the "swiss cheese/soap bubble" appearance on T2WI and heterogeneous moderate enhancement on MR images; (3) the incorporation of the septum pellucidum in bilateral tumours and abutting of the septum pellucidum in unilateral tumours together with the attachment of the wall of the ventricles can help in the diagnosis of preoperative central neurocytoma. Central neurocytoma (CN) was first described in the 1980’s by Hassoun et al. Epub 2016 Apr 23. A relatively short clinical course, typically only a few months, is most common.

Figure 1: histology - "salt and pepper" appearance, Intraventricular meningioma - third ventricle, typically iso to somewhat hyperintense compared to brain, numerous cystic areas (bubbly appearance), many of which completely attenuate on FLAIR, calcification is common, typically punctate, hemorrhage (especially in larger tumors) is common, uncommonly results in ventricular hemorrhage, diffusion restriction of the solid component, glycine peak (3.55ppm) has also been reported, supratentorial tumors (esp in children) often have a significant extraventricular (parenchymal) component, may have ependymoma components and look very similar, typically show intense contrast enhancement, this is especially difficult in cases where there is a parenchymal component as histologically the tumors are very similar. Accompanying ventricular dilatation often present. We report a case of neurocytoma located in the fourth ventricle and extended into the third ventricle. NIH A surgical biopsy of the lesion was taken. Dr Balaji Anvekar FRCR Neuro and MSK Consultant Radiologist. Contrast enhancement is usually mild to moderate. Two radiologists read the images retrospectively. CN is a benign tu-mor of the central nervous system that is classified as a grade II tumor by the World Health Organization (WHO) [2,3]. Central neurocytoma is a recently described, rare primary brain tumor of neuronal origin, which is characterized by predominant occurrence in the young adults, exclusive later- al ventricular location, and oligodendroglioma-like histolo- gy (1,8, 12-14, 17).

Calcification is seen in over half of cases, usually punctate in nature 4,10. A number of cases have been reported after this tumor was first described by Hassoun et al in 1982. When only incomplete resection possible or extraventricular extension is present, then adjuvant radiotherapy (and sometimes chemotherapy) are added, although their benefit is not well established.

Heterogeneous moderate enhancement (5/8) was present on T1 postcontrast images. It usually occurs in young adults with no sex predilection and constitutes approximately 0.1-0.5 % of all intracranial tumours [1-2]. A tumor blush is frequently identified, with the mass supplied by choroidal vessels. Immunohistochemistry confirms the purely neuronal origin by positivity to neuronal markers such as 11: Importantly, IDH mutations and 1p19q co-deletion are absent (characteristic of oligodendrogliomas). Extraventricular neurocytoma with ganglionic differentiation associated with complex partial seizures. Isaac Yang. RTU-26. Materials and methods: Objectives: Central neurocytomas demonstrate neuronal differentiation and histologically appear similar to oligodendrogliomas which, historically, resulted in many tumors erroneously categorized.
