Introduction. Subcutaneous emphysema is usually benign and self-limited; however, it may be associated with a life-threating situation. Case Report. An elderly woman with progressive malaise with extensive subcutaneous emphysema (cervical to abdominal wall) was observed at the emergency department. Colonic perforation was diagnosed and the patient underwent surgery. Intraoperatively, necrosis and perforation of the sigmoid colon into the retroperitoneum were found and a Hartmann procedure was performed. Conclusion. Cervical and thoracic subcutaneous emphysema may be the first sign of intra-abdominal lesion.
