【 摘 要 】

Various complications have been associated with epidural block; pneumocephalus is one of the rare complications.We report a case of pneumocephalus following epidural catheter placement in a 58 years old female patient referredto our pain clinic for pain hypogastrium. After careful history and physical examination the diagnosis of neuropathicpain was established. The pain did not relieve with the pharmacological treatment, so superior hypogastric ganglionblock was performed. The patient remained pain free for a week, after which the complaints recurred. Then an epiduralcatheter was attempted twice but abandoned after two failed attempts. The catheter perforated the dura mater leadingto flow of CSF. After a few hours the patient developed a complaint of severe headache. The patient was hospitalisedand intravenous NSAID’s were started. However, the headache did not relieve, so CT scan brain was ordered, whichdetermined the presence of pneumocephalus. The patient was offered symptomatic treatment and after a week wasdischarged home without any complication.
