    Abstract:
    Introduction. The most prominent complications of cocaine use are adverse effects in the cardiovascular and central nervous systems. Free air in the mediastinum and subcutaneous tissue may be observed less frequently, whereas free air in the spinal canal (pneumorrhachis) is a very rare complication of cocaine abuse. In this report we present a case of pneumorrhachis that developed after cocaine use. Case. A 28-year-old male patient was admitted to the emergency department with shortness of breath, chest pain, and swelling in the neck and face which started four hours after he had sniffed cocaine. On physical examination, subcutaneous crepitations were felt with palpation of the jaw, neck, and upper chest area. Diffuse subcutaneous emphysema, pneumomediastinum, and pneumorrhachis were detected in the computed tomography imaging. The patient was treated conservatively and discharged uneventfully. Discussion. Complications such as pneumothorax, pneumomediastinum, and pneumoperitoneum that are associated with cocaine use may be seen due to increased intrathoracic pressure. The air then may flow into the spinal canal resulting in pneumorrhachis. Emergency physicians should know the possible complications of cocaine use and be prepared for rare complications such as pneumorrhachis.
