The sections show a partially cystic vascular tumour with histomorphological normal endothelial cells and vacuolated polygonal cells with hyperchromatic nuclei. There is no mitotic activity. Immunohistochemical staining shows that the tumour is positive focally and weakly for inhibin and is strongly positive for neuron-specific enolase (NSE). | The sections show a partially cystic vascular tumour with histomorphological normal endothelial cells and vacuolated polygonal cells with hyperchromatic nuclei. There is no mitotic activity. The tumour has a poorly demarcated border. Cerebellum adjacent to the tumour demonstrates Purkinje cell loss and Bergmann gliosis. | ||
