title: Intrathyroidal multiloculated proliferating thymic cyst.
abstract: Ectopic thymic tissue in neck is not uncommon; however, ectopic thymic cysts in neck are rare and intrathyroidal thymic cyst is still rarer. Multilocular proliferating thymic cyst is a rare entity and very few cases are described in mediastinum. We present the first case of a 73-year-old male with an intrathyroidal multilocular proliferating thymic cyst mimicking thyroid malignancy radiologically.
