Long-term follow-up of lateral ventricular central neurocytoma treated with subtotal resection followed by concurrent chemoradiotherapy and add on chemotherapy – Case report from a Tertiary Kenyan Cancer Hospital

BACKGROUND: Central neurocytomas are rare, mostly benign neuroectodermal tumors of the central nervous system typically located within the lateral and third ventricles of cerebrum. No consensus guidelines for the management of central neurocytoma available due to the rarity of the disease. CASE DESCRIPTION: We report a case of right ventricular central neurocytoma of a 28-year-old lady who had a subtotal resection and ventriculoperitoneal shunting. Postoperatively, she was treated with concomitant chemotherapy with oral temozolomide and radiotherapy, followed by add-on chemotherapy with same drug. Imaging, microscopic evaluation, treatment modalities, and outcome of treatment are presented. CONCLUSION: Subtotal resection of tumor through transcallosal approach and ventriculoperitoneal shunt was performed. Imaging done 2 weeks postsurgery confirmed residual disease. Concurrent chemoradiotherapy (54 Gy in 30 fractions +Oral Temozolomide 75 mg/m(2) daily), followed by six cycles of 5-day chemotherapy with temozolomide (150 mg/m(2) in Cycle 1, and 175 mg/m(2) in subsequent cycles) at 28-day intervals, was given. No major toxicities encountered. Follow-up scan after 36 months showed complete remission.
