Oman Medical Specialty Board A 45 year old male presented with chronic headache for the last six months, with recent aggravation. he headache was holocranial in nature and not associated with vomiting, aura or any other neurological complaints. On examination, he had no neurological deicit. Neuroimaging was performed (contrast enhanced MRI) which revealed features suggestive of intraventricular neurocytoma with intraventricular hemorrhage (Figs. 1-3). He underwent gross total excision of tumor after frontal craniotomy and through anterior transcallosal approach. Histopathology suggested a diagnosis of neurocytoma WHO grade II. . Figure 1a: AAxial T1 weighted image of the brain revealed a mass lesion in right lateral ventricle with heterogeneous signal intensity and hyperintensity in the frontal horn of right lateral ventricle suggesting intraventricular hemorrhage. Figure 1b: Axial T2 weighted MR image reveals heterogeneous hyperintense signal intensity of the mass lesion. Figure 2: Coronal T2 Weighted MR image reveals the mass lesion to be located in the frontal horn of right lateral ventricle and typical contralateral displacement of the septum pellucidum (arrow).
