Clinical outcome and prognostic factors for central neurocytoma, a study of 14 cases

Background: Since they’re rare, the intraventricular neoplasms “central neurocytoma” best management got diverse, and mystifying. Aim of the work: to assess outcome for patients with central neurocytoma and value of specific factors like tumor size, surgical resection extent, atypia, and concomitant other modality of treatments by radiotherapy in their survival. Patients & methods: 14 patients (8 males, 6 females) were managed surgically between 2012 and 2016. They were assessed clinically, radiologically and their outcome in relation to selected factors. Results: Median age at diagnosis was 28.3 years in average (range 16–58). Median follow-up was 32.2 months.we lost 2 cases to follow-up in post-operative period. Six patients had recurrent of neurocytoma tumours.Five patients (35.7 %) obtained gross total resections (GTR) while 9 patients (64.2 %) had subtotal resections (STR). Two STR patients (14.2 %) received dose of radiation post operatively that significantly enhanced overall PFS (p =0.047). our series data propose that radiation therapy following (STR) usually increase (PFS). Two patients proved to have atypical neurocytoma by pathological reports died at 2.3 and 10.2 months after the microsurgical procedures. MIB-1 tagging index higher than 4 % is an indicator for poor outcome. We used Kaplan–Meier beside Cox proportional hazards methods in determining the Progression-free survival (PFS) in our study. Conclusion: the extent of surgical resection may improve the neurological condition but not the survival, Atypia was the most important factor determine the recurrence & survival while radiotherapy improve the survival quietly.

Pontine Atypical Neurocytoma: Case Report

OBJECTIVE AND IMPORTANCE: Neurocytomas are typically located within the supratentorial ventricular system. Extraventricular neurocytomas are very rare, and this is only the second reported case of a pontine neurocytoma. We discuss the clinical presentation, histology, and treatment of these rare tumors. CLINICAL PRESENTATION: A 58-year-old man presented with a 4-month history of headache and unilateral facial and distal extremity paresthesia. Magnetic resonance imaging (MRI) scans demonstrated a 2.6 × 2.2-cm ring-enhancing cystic mass in the right pons. INTERVENTION: MRI-guided stereotactic biopsy yielded a diagnosis of atypical neurocytoma. Because of the location and malignant histological features of the tumor, the patient was initially treated with external beam radiation therapy. Several months later, MRI scans demonstrated tumor progression. The patient then underwent three rounds of temozolomide chemotherapy, during and after which his symptoms worsened. Aggressive subtotal resection of the tumor was achieved via a right suboccipital craniectomy. CONCLUSION: Twenty-eight months postoperatively, the patient is symptom free, and MRI scans demonstrate no evidence of residual or recurrent tumor.
