A Rare Case of Thyrolipomatosis Presenting with Latent Hyperthyroidism

Goiter and hyperthyroidism are fairly common problems in the Indian population. We present a 49-year-old female who presented with thyroid swelling and suppressed thyroid-stimulating hormone. On evaluation, she was having latent hyperthyroidism with diffuse and soft thyroid swelling. During the evaluation for feasibility of radioiodine ablation, she was found to have thyrolipomatosis on computed tomography. She was counseled for total thyroidectomy and subsequently underwent the same with histopathology confirming the presence of fatty infiltration into the thyroid stroma.
