[Pituitary necrosis after spinal anesthesia : a case report].

Spinal anesthesia was administered to a patient for the surgical reduction of an inguinal hernia. However, the procedure was complicated by corticotropic insufficiency secondary to the necrosis of a non-secretory hypophyseal adenoma. The clinical presentation is discussed here together with both medical and neurosurgical managements. Etiology and pathophysiological mechanisms of this complication are analyzed in accordance with the most recent of the literature.
