A 26-year-old woman patient, previously healthy, is an airline stewardess. On a recent fl ight, after lifting some heavy passenger baggage in her duties to the overhead shelf by using the power of her whole body, she felt nausea and headache. They both increased that evening and in a standing position, but improved in a supine position. Spinal fluid leakage was observed by her computed tomography (CT) -myelography, and she was diagnosed with cerebrospinal fluid hypovolemia (CFH). We performed a continuous epidural saline infusion as treatment to her, and her symptoms and activities of daily living improved. It was then possible for us to treat CFH safely and effectively without epidural autologous blood infusion, which is well-known and can have many complications. Also, though the pathogenesis of CFH in a nontraumatic case is unknown, stretching exercises such as lifting heavy baggage overhead possibly caused CFH in this case.
