===2017=== A 52-year-old man was admitted to the neurosurgery clinic with severe [[headache]], retro-orbital pain, and blurred vision. [[Lumbar puncture]] demonstrated that the CSF opening pressure was 32 cm H 2 O. A nonprogrammable [[lumboperitoneal shunt]] with two distal slit valves was inserted. Shortly after the surgery, his condition deteriorated and he became [[coma]]tose. Immediate computed tomography scan revealed cerebellar hemorrhage and acute [[hydrocephalus]]. Development of remote cerebellar hemorrhage following LP shunt is rare ((Ayvalık F, Ozay R, Turkoglu E, Balkan MS, Şekerci Z. Remote Cerebellar Hemorrhage Following Lumboperitoneal Shunt Insertion: A Rare Case Report. Surg J (N Y). 2016 Dec 1;2(4):e139-e142. doi: 10.1055/s-0036-1594245. eCollection 2016 Oct. PubMed PMID: 28825007; PubMed Central PMCID: PMC5553480. )). ---- A 62-year-old patient with RCH encountered following surgical clipping of an unruptured middle cerebral artery bifurcation aneurysm in a patient with previous cerebellar infarction. It is extremely rare, but sometimes, RCH can be life-threatening. It is necessary to check the patient's general condition, underlying diseases and medical history. And controlled drainage of the CSF seems to be most important. Arachnoidplasty may be a consideration and the position of the drain string might have to be carefully determined ((Koh EJ, Park JS. Fatal [[remote cerebellar hemorrhage]] after supratentorial unruptured aneurysm surgery in patient with previous cerebellar infarction: A case report. Medicine (Baltimore). 2017 Jan;96(4):e5938. doi: 10.1097/MD.0000000000005938. PubMed PMID: 28121936. )).
