Based on the clinical, biochemical, and radiological findings, a TSH-secreting adenoma (TSHoma) diagnosis was made. Octreotide was administered; however, thyroid function tests (TFT) showed no improvement, even at the maximum dose of octreotide LAR. As other somatostatin analogs were unavailable in the country, carbimazole was given to stabilize TFT levels before surgery.
