Abstract
A 34-year-old woman came to the emergency room complaining of a severe orthostatic headache. Results of a cerebrospinal fluid tap and brain computed tomography were normal. Based on her history and symptoms, she was found to have spontaneous intracranial hypotension. She was hospitalized and her symptoms improved with conservative treatment. On the next day, her headache suddenly worsened. Cisternography was performed to confirm the diagnosis and determine the spinal level of her cerebrospinal fluid leak. It revealed multiple cerebrospinal fluid leaks in the lumbar and upper thoracic regions. It was strongly believed that she had an iatrogenic cerebrospinal fluid leak in the lumbar region. An epidural blood patch was performed level by level on the lumbar and upper thoracic regions. Her symptoms resolved after the epidural blood patch and she was later discharged without any complications. In this case, an iatrogenic cerebrospinal fluid leak was caused by a dural puncture made while diagnosing spontaneous intracranial hypotension, which is always a risk and hampers the patient's progress. Therefore, in cases of spontaneous intracranial hypotension, an effort to minimize dural punctures is needed and a non-invasive test such as magnetic resonance imaging should be considered first.
