Symptomatic Pneumorrhachis from Bronchial-Subarachnoid Fistula.

Area of Science:

• Neurology
• Thoracic Surgery
• Radiology

Background:

• Bronchial-subarachnoid fistulas are rare and poorly defined, potentially causing symptomatic pneumorrhachis.
• Pneumorrhachis, air in the spinal canal, can arise from various causes, presenting diagnostic and therapeutic challenges.

Purpose of the Study:

• To present a case of bronchial-subarachnoid fistula secondary to thoracic chondrosarcoma treatment.
• To detail the diagnostic process and successful management of this rare condition.

Main Methods:

• Computed tomography (CT) scan for diagnosis.
• High-flow oxygen therapy and bed rest.
• Surgical correction of pleural air leak and dural defect.

Main Results:

• A 53-year-old female developed pneumorrhachis due to a bronchial-subarachnoid fistula post-thoracic spine surgery.
• Symptoms included headache, neck/back spasms, and confusion.
• Successful treatment led to clinical resolution at six months post-repair.

Conclusions:

• Bronchial-subarachnoid fistulas are a rare cause of pneumorrhachis requiring prompt diagnosis and intervention.
• Multimodal treatment, including surgical repair, can be effective.
• Further research is needed to understand and manage this condition better.
