Chronic Pituitary Failure Resembling Sheehan's Syndrome Following a Bite of Russell's Viper. A Case Report.

Hypopituitarism can be the sequela of a variety of causes like postpartum pituitary necrosis or Sheehan's syndrome, lymphocytic hypophysitis, trauma and encephalitis. A very rare cause is envenomation by a bite of a Russell's viper. Very few cases with documented imaging findings of chronic pituitary failure resulting from snake bite have been reported. We describe a case of hypopituitarism with clinical, endocrine and magnetic resonance (MR) imaging studies occurring as a delayed complication of snake bite.
