Cough-induced costal cartilage fracture


      We present two cases of atraumatic costal cartilage fracture secondary to violent coughing. Although costal cartilage fractures due to trauma and bony rib fractures due to violent coughing have been described, to our knowledge there have been no prior reported cases of cough-induced costal cartilage fracture. It is important for radiologists to consider costal cartilage fractures, which are often more subtle than osseous injuries, in patients with chest pain, and understand that they may not always be preceded by direct trauma. Identifying this injury is clinically important and will prevent patients from undergoing unnecessary examinations to rule out a cardiac cause of chest pain or a pulmonary embolism.
