Primary cerebral neuroblastoma: Long-term follow-up review and therapeutic guidelines

摘要: Primary cerebral neuroblastoma is a distinct pathological and clinical entity that differs from other primitive neuroectodermal tumors. To characterize the course of this lesion, authors performed retrospective analysis in 11 patients who ranged age 17 months to 26 years. The tumor had no predilection for either sex. Signs symptoms were mostly those associated with increased intracranial pressure. lesions commonly involved parietal occipital lobes. Computerized tomography scans nine showed five solid four cystic lesions; calcifications found more lesions. Contrast enhancement was seen all tumors, yet angiograms typically an avascular mass. Total removal possible only two patients, both remaining underwent subtotal resection lesion (in five) or four). All postoperative irradiation included spinal axis cases; one received adjuvant chemotherapy (solid tumor). Four tumors initially subtotally resected, evidence recurrence. patient resected did not have recurrence chemotherapy. six are free recurrent at 109 after surgery. Based on follow-up recommendations proposed treatment primary neuroblastomas.
