Effects of octreotide therapy on permanent atrial fibrillation in a patient with TSH adenoma- Case report
Secondary hyperthyroidism due to a thyrotropin - secreting (TSH) pituitary adenoma is a rare cause of hyperthyroidism, representing 0.5-2.0% of all pituitary adenomas. We report a case of a 36 year old female who presented with signs of thyrotoxicosis, elevated T3, T4, TSH, atrial fibrillation, as a result of TSH adenoma. She was successfully treated with Somatostatin analogue without surgical intervention. The investigation and treatment of this condition is discussed.
