[Persistent subarachnoid-pleural cerebrospinal fluid fistula following excision of a thoracic ganglioneuroma. Case report].

During extirpation of a thoracic ganglioneuroma, haemostasis of venous haemorrhage by application of bone wax close to the costovertebral junction at Th 4/5 resulted in plegia of the lower extremities on the fourth postoperative day. Compression of the myelon due to the applied bone wax was relieved directly after CT scan diagnosis. In the postoperative course, a persisting subarachnoidal pleural fistula was closed by means of muscle flap plasty and fibrin adhesive.
