Ultrastructural study of hemangiomas. 3. Specific endothelial granules in the cerebellar hemangioblastoma.
We report a case of cerebellar hemangioblastoma in a 45-year-old man. To our knowledge, only two papers have been reported previously on the cystic inclusions other than Weibel-Palade bodies in the endothelial cells, and this is the first reported case of a hemangioblastoma exhibiting large, cystic endothelial inclusions with microtubular subunits. The function of these inclusions is obscure.
