Central neurocytoma presenting with intratumoral hemorrhage 15 years after initial treatment by partial removal and irradiation.
A 50-year-old male presented with a central neurocytoma with intratumoral homorrhage. He had undergone partial removal of the tumor and postoperative radiation therapy 15 years previously. He was followed as an outpatient after the initial treatment, and there was no evidence of regrowth of the residual tumor. Removal of the hematoma and biopsy of the tumor were performed. Abnormally developed blood capillaries in the tumor may have undergone disturbances of circulation caused by irradiation which resulted in bleeding. Patients with partially resected central neurocytomas which have low proliferative potential may not require radiation therapy, due to the benign nature and the risk of delayed complications of irradiation including intratumoral hemorrhage.
