To describe the clinical and imaging characteristics of patients with central neurocytoma
(CN), we reviewed data on 27 patients who had histologically confirmed CN and were
treated in our institution between 1999 and 2010. Neuro-imaging findings on CT scan (n=
18) and MRI (n= 25) were retrospectively evaluated. There were 15 males and 12 females
with a mean age of 29years (range, 11–46years). The most frequent presentations included
headache (n= 21) and vomiting (n= 6). Tumor sites included bilateral lateral ventricles (n …
To describe the clinical and imaging characteristics of patients with central neurocytoma (CN), we reviewed data on 27 patients who had histologically confirmed CN and were treated in our institution between 1999 and 2010. Neuro-imaging findings on CT scan (n=18) and MRI (n=25) were retrospectively evaluated. There were 15 males and 12 females with a mean age of 29years (range, 11–46years). The most frequent presentations included headache (n=21) and vomiting (n=6). Tumor sites included bilateral lateral ventricles (n=10), right lateral ventricle (n=7), left lateral ventricle (n=7) and fourth ventricle (n=3). On MRI, the T1-weighted signal was hypointense in 12 patients and isointense in 13, and the T2-weighted signal was isointense in 8 patients and hyperintense in 15. CT scans/MRI revealed a cystic component in 18 patients. Tumors showed a mild to marked enhancement in 26 patients. Flow voids from tumor vessels on MRI were present in 14 patients, and calcification was noted in six of 18 patients with CT scans. All lateral ventricle tumors were resected through a transcortical or transcallosal approach. Gross total resection was achieved in 19 patients, near total in two and subtotal in six. One patient died of cerebral infarction in the perioperative period. At the last follow up, there were three known clinical recurrences in this series. However, no recurrence was noted in 17 patients who underwent gross total resection with no adjuvant therapy.
