Introduction: TSH adenoma is the rarest cause of hyperthyroidism. We report the case of a 22-year-old female patient followed for hyperthyroidism revealing a TSH adenoma.
Case Observation: A 22-year-old female patient with no previous history presented a thyrotoxicosis syndrome with no amenorrhea, no galactorrhea or amenorrhea or recent weight gain. She experienced no dizziness, headaches or vomiting. Biological investigations were normal except for TSH or thyrotropin, which was elevated, associated with an increase tetraiodothyronine. A magnetic resonance imaging revealed a pituitary adenoma. Further investigation of other hormonal axes came back normal. The patient was put on carbimazole (40mg/day), propranolol and anxiolytics. A neurosurgical opinion was requested. We observed a good clinical evolution with regression of signs of thyrotoxicosis.
Conclusion: TSH pituitary adenoma is a pathology that is rarely described in the literature. Its treatment requires good coordination between surgeons and internists or endocrinologists.
