Subcutaneous emphysema refers to the presence of air in the subcutaneous planes of the body. It may result from a benign cause like trauma, accidental injection, or entry of air through a negative pressure gradient, or it could be a part of the life-threatening ailment in the form of necrotizing fasciitis with gas gangrene. We report a 31-year-old male who sustained trauma to the hand followed by pressurized air injection into the wound resulting in the subcutaneous emphysema of the left upper limb. Imaging studies confirmed the presence of subcutaneous emphysema. The patient was managed conservatively with limb immobilization. Being rarely reported in the medical literature, we aim to improve the awareness of such a condition and beware of impending complications.
Keywords: air gun; compartment syndrome; crepitus; pressurized air; subcutaneous emphysema.
