[Cerebellar haemorrhage after lumbar surgery with intraoperative dural tear].

In this case report, a 71-year-old female developed headache and nausea and signs of brain stem involvement following lumbar surgery with intraoperative dural tear. A CT scan showed cerebellar haemorrhage and hydrocephalus, and the patient was transferred to a neurosurgical department and treated with an external ventricular drainage, haematoma evacuation, and posterior fossa decompression. This case highlights the importance of swift diagnostics in patients developing neurological symptoms following lumbar surgery, as well as limiting any cerebrospinal fluid leakage following intraoperative dural tear.
