Case 301: Traumatic Subarachnoid-Pleural Fistula.

A 38-year-old man who had been in a motor vehicle collision was referred to our institute. He was suspected of having left-sided pneumothorax. This necessitated intercostal drainage with a chest tube, which had been placed elsewhere prior to his arrival. Paraparesis was noted at the initial clinical examination, with adequately maintained vital signs, while the blood work-up revealed a mildly reduced hemoglobin level of 10.1 mg/dL (normal range, 13.8-17.2 mg/dL); however, the rest of the laboratory values were within normal limits. The patient was then immediately referred for further evaluation with CT of the brain, cervical spine, and thorax. Thereafter, serial chest radiography was performed for follow-up.
