Subarachnoid-pleural fistula complicating thoracotomy

Transosseous cerebrospinal fluid fistula 14 years after Chiari decompression: presentation and management

“…Although subarachnoid-pleural and subarachnoid-mediastinal fistulas 7,16,17,20 have been noted in the spine after trauma (either as a result of rupture of a known spinal meningocele or in association with significant spinal column disruption and concomitant dural laceration), the existence of an acquired intraosseous CSF fistula similar to our case has, to our knowledge, not been previously reported. A very recent report by Mahaney and Menezes 11 described an occipital intradiploic pseudomeningocele, arising within the dorsal occipitocervical fusion mass and resulting in dorsal hindbrain compression in a patient with a remote history of Chiari decompression.…”

Case report: Epidural blood patches are effective in treating intracranial hypotension due to a subarachnoid-pleural fistula

“…This may be because an intercostal nerve dural sleeve tear is easily overlooked, as it can be obscured by fat or peridural venous oozing at the level of the neural foramen ( 4 ). After a root avulsion, the CSF outflow causes cerebral collapse with arachnoid mater tearing and air entry into the intracranial subdural space through defects due to thoracotomy, leading to intracranial pneumatosis ( 20 ). This is what we observed on this patient's cranial CT, which was performed on day 5 postoperatively.…”

What you don’t want to see after a superior sulcus tumor resection?: a tension pneumocephalus

“…In the literature, the number of days between the operation and the onset of pneumocephalus findings varies considerably. Pneumocephalus may present in the early postoperative period, as well as in the relatively later period, such as the 19th day or 30th day [2,3]. This difference also depends on the differences or severity of the pathophysiology of the pneumocephalus mentioned above.…”
