Pituitary Macroadenoma: A Rare Presentation of Hypothyroidism

Hypothyroidism is a common endocrine disease which occurs when the levels of Thyroid hormones produced by the Thyroid gland are decreased. Here we present a case of a 19-year-old female, who presented with symptoms of hyperprolactinemia, weight gain, unilateral blurring of eyes and headache. Examination findings of the patient were significant for presence of Acanthosis Nigricans and Hirsutism. Rest of the systemic examination was normal. Laboratory investigations revealed Hyperprolactinemia, Hypothyroid profile and dyslipidemia. MRI brain and pituitary done showed findings consistent with Pituitary macroadenoma. Patient was treated along the lines of hypothyroidism with Thyroxine. Follow-up after 3 months showed improvement of her symptoms and disappearance of lesion of MRI scan. This case was a rare presentation of Hypothyroidism. Such unusual and uncommon presentations should be reported and studied in detail to prevent misdiagnosis and provide the correct treatment to the patients.
