Chronic subdural hematoma is a common neurosurgical problem, especially in the elderly, which is frequently treated by burr hole drainage. Recurrence is the most frequent complication of chronic subdural hematoma surgery reported in literature. However, cerebrospinal fluid leak resulting subgaleal pseudomeningooele has been reported. We report a 67-year-old man who had burr hole drainage of chronic subdural hematoma and subsequently developed cerebrospinal fluid fistula which was drained by subdural drain inserted intraoperatively. A 67-year-old right-handed man who presented with nine days' history of progressive pan-cranial persistent headache following a fall from the bathroom associated with irrational behavior and weakness of the left side of the body. His Glasgow Coma Score (GCS) was 12/15, with generalized hypertonia, left-sided hemiparesis, and left-sided grade + 3 deep tendon reflexes. Brain computed tomography scan [Figure 1] showed right-sided fronto-temporoparietal chronic subdural hematoma with midline shift and effacement of the ipsilateral lateral ventricle. He had right frontal and right parietal burr holes, such as subdural hematoma and insertion of nonnegative subdural drain through the parietal burr hole. He developed cerebrospinal fluid leak, which drained into the drainage bag and subsequently managed conservatively. Cerebrospinal fluid leaks can occur following burr hole drainage of chronic subdural hematoma. Subdural drain inserted intraoperatively is helpful in preventing the sequelae of cerebrospinal fluid accumulation in the subdural and subgaleal spaces.
