Hypopituitarism secondary to transfacial gunshot wound.

Hypopituitarism secondary to penetrating head trauma is extremely rare, and its diagnosis may be delayed for several years. We present a patient who developed hypopituitarism secondary to a transfacial gunshot wound and who experienced damage to the hypophysis secondary to transmission of energy and bullet fragments. The importance of a computerized tomographic scan of the head in facial gunshot wound is discussed.
