The MRI shows a 1.0 x 1.0 cm c2 intramedullary lesion which was demarcated as a homogeneous mass with a contrast-enhancing nodule associated with a cystic portion and flow voids that were characteristics of hemangioblastoma [Figure 1].
HISTOPATHOLOGIC STUDY: Neoplastic cells with clear cytoplasm, hyperchromatic nucleus and a small vascularized network between neoplastic cells.
