Bilateral remote cerebellar hemorrhage following surgical clipping a ruptured supratentorial aneurysm

Remote cerebellar hemorrhage (RCH) is a rare and severe complication after supratentorial surgery, with various risk factors and mechanisms remaining uncertain. Herein, we report a 64-year-old female patient suffered bilateral RCH following surgical clipping a ruptured aneurysm of internal carotid artery bifurcation. RCH is considered as venous in origin, and is likely the result of intra-operative or post-operative loss of CSF. Thus, appropriate control and close monitor the intra-operative and post-operative loss of CSF is of great importance for preventing the occurrence of RCH.
