Unusual Presentation of Primary Hypothyroidism.

Primary hypothyroidism may present with myriad of unusual presentation apart from typically described signs and symptoms. We report an unusual case of primary hypothyroidism clinically presenting as acute psychosis and radiologically mimicking as pituitary macroadenoma. A 19-year-old female presented with h/o abnormal behaviour in the form of auditory hallucination, fearfulness, loss of memory and inability to recognise family members six months back. She also gave h/o multiple joint pain, easy fatigability, facial puffiness, somnolence, progressive weight gain, constipation and cold intolerance for similar duration. MRI brain revealed enlarged pituitary, while the thyroid function analysis pointed towards primary hypothyroidism. Patient improved with LT4.

Acute Psychosis Following Hydrocortisone Replacement in a Patient with Secondary Adrenal Insufficiency Due to Recurrent Postoperative Pituitary Macroadenoma.

Acute psychosis in patients receiving physiological corticosteroid replacement is rare. The exact mechanism of this disorder is not clear. We report a case of a 50 year old female with recurrent post operative pituitary macroadenoma who had presented to us with features of adrenocortical insufficiency. The patient was started on intravenous (iv) hydrocortisone and after receiving six doses, she developed features of acute psychosis. She was put on anti-psychotics and hydrocortisone was withheld for 24 hrs. The patient recovered in a couple of days and oral hydrocortisone was re-started at 5 mg per/day and increased to 15 mg/day without recurrence of symptoms of psychosis.
