“…Two exceptional cases with massive tetraventricular extension have been reported. 26,37 No examples of central neurocytoma arising from and confined to the fourth ventricle have been reported. Although several instances of intraparenchymal neurocytomas have been described, the relationship of these tumors to intraventricular neurocytomas and other low grade entities, such as dysembryoplastic neuroepithelial tumors, is uncertain and requires further study.…”

Central neurocytoma was first described in the literature in 1982 and has been noted to be a benign neuronal tumor usually located in the ventricular system. Of the more than 100 reported cases, only seven recurrences have been reported, all of which have been local. The authors report two cases of recurrent central neurocytoma that disseminated through the ventricular system with seeding to the spine, as evidenced by magnetic resonance images and positive cerebrospinal fluid cytology. The histological appearance of these two tumors was typical for the lesion and lacked evidence of malignant change. Central neurocytoma may not be as benign as previously thought, and the recognition of this more malignant behavior has implications for patient follow up and therapy.

“…[ 6 7 8 9 ] Tetraventricular involvement of the disease is extremely rare and to our knowledge only two cases were reported in the literature. [ 10 11 ] This is the third tetraventricular CN case with classical neuroimaging and histopathological findings including DWI. On DWI sequence, the tumor shows heterogeneous high signal intensity to the brain with a corresponding low ADC value consisted with restricted diffusion.…”

Central neurocytoma (CN) is a benign intraventricular neuronal tumor with a favorable prognosis. It accounts approximately 0.25–0.5% of intracranial tumors. In this report, we describe a very rare case of tetraventricular CN with imaging-pathologic correlation, and discuss their atypical features in a location together with treatment options. A 27-year-old man was admitted to the hospital with symptoms of progressive headaches of several months’ duration. Magnetic resonance imaging of the brain revealed a well-circumscribed, lobulated intraventricular mass with numerous intratumoral cystlike areas. The mass was located in the enlarged lateral ventricles bilaterally extending to the third and the fourth ventricle. Surgical removal of the 4th ventricle component of the tumor was performed. Histomorphological and immunohistochemical findings of the tumor were consistent with CN. After pathological diagnosis, gamma knife surgery was performed. CN may present with atypical features in a location with a usual histopathological findings. To our knowledge, we described the third case of tetraventricular CN, which was partially treated with both surgical resection and radiosurgery.
