Iatrogenic intracranial hypotension secondary to subarachnoid-pleural fistula after transthoracic surgery for the treatment of lateral thoracic meningocele.

Subarachnoid-pleural fistula (SPF), a rare complication following transthoracic spinal surgery, results in the accumulation of cerebrospinal fluid (CSF) in the pleural space. Hindered spontaneous closure, attributed to negative pleural pressure, gives rise to CSF hypotension and subdural blood collections. Despite numerous reported cases, achieving consensus on management remains elusive.
