Cerebellar lesion, excision: hemangioblastoma.
Final Diagnosis Comment:
The focal areas of necrosis are likely ischemic in nature.
Sections show a moderately cellular neoplasm that is well circumscribed from the adjacent cerebellar tissue. There are many thin-walled blood vessels of various sizes, separated by sheets of polygonal stromal cells with pleomorphic nuclei and abundant foamy cytoplasm. Rare mitoses are present. There are focal areas of necrosis and sclerosis that are possibly ischemic in nature.
