Thyrotropinoma with Graves’ disease detected by the fusion of indium-111 octreotide scintigraphy and pituitary magnetic resonance imaging

Thyroid-stimulating hormone-secreting pituitary adenoma (TSHoma) is a rare benign endocrinological tumor which produces TSH in the pituitary gland. Herein, we presented a female patient having TSHoma with Graves′ disease during and just after pregnancy that we found by indium-111 octreotide scintigraphy while investigating the patient for hyperthyroidism symptoms.
