title: Central neurocytoma occurring in the thalamus: CT and MRI findings.
abstract: A case of central neurocytoma occurring in the thalamus, confirmed by electron microscopy and immunohistochemistry, is reported. Computed tomography demonstrated a hypodense mass with an irregular margin arising from the right thalamus, extending into the lateral ventricle and crossing the midline. It contained areas of calcification and showed slight enhancement after contrast injection. On magnetic resonance imaging (MRI) scan, the tumour was hypointense to the brain in T1-weighted images and was heterogeneously hyperintense to the brain in T2-weighted images.
