Subcutaneous emphysema is the presence of air within the subcutaneous tissue. Its cause is likely trauma and surgery. Other causes are rare. We report a case of tubercular subcutaneous emphysema with a fistula between airway and subcutaneous tissue diagnosed by 3D virtual bronchoscopy and confirmed by bronchoscopy.
Case Report: NECT BRAIN shows presence of air within the subcutaneous plane. CT THORAX shows subcutaneous plane and cavitation and nodule within the lungs. CT 3D virtual bronchoscopy shows a dimple suggesting a fistula formation. With proper Anti- TB treatment there's resolving of air within the subcutaneous plane and resolving of lung changes.
