Аннотация
BACKGROUND: Hemorrhage as a presenting feature in pilocytic astrocytoma is an extremely rare phenomenon. When seen in children, most of such tumors exist in the cerebellum. Rarely, a supratentorial pilocytic astrocytoma can present with bleeding.
RESULTS: We present similar two cases and discuss the pathophysiology of such hemorrhage and histopathological changes in thinned hyalinised vessels of this tumor.
CONCLUSION: The presence of calcifications in the peri-hemorrhagic areas and the presence of mass effect disproportionate to the size of the bleeding are harbingers of the presence of a benign neoplasm that may have bled.
