An Unusual Case of Intractable Vomiting: Unravelling the Present, Through the Past!
Keywords
Abstract
A 54 year old lady presented to our institute with a history of low grade fever for one week associated with occasional loose stools, vomiting and severe malaise. Initial evaluation revealed low serum sodium. An initial diagnosis of acute gastroenteritis with secondary hyponatremia was made. Work up for infective causes of gastroenteritis was however negative. ENT evaluation and review of drug history did not contribute towards a diagnosis. The patient's symptoms persisted and did not respond to symptomatic treatment. Ultrasound of abdomen revealed cholelithiasis with no evidence of cholecystitis. Further evaluation revealed hypotonic hyponatremia with normal levels of urinary sodium excretion. With other causes of hyponatremia ruled out, an endocrinopathy was suspected as the likely culprit. Follow up hormonal studies revealed hypopituitarism and MRI of brain revealed a partially empty sella. On reviewing the case, a past history of amenorrhea immediately after the birth of her third child (almost 20 years ago!) was elicited. Intractable vomiting is quite an unusual presentation for Sheehan's syndrome, but a thorough case history coupled with a high index of suspicion can contribute towards identifying the cause among a series of confounding clinical and radiological findings, as in our case.
