Enormous thymolipoma: A case report

Abstract Thymolipoma is unusual benign mediastinal, slow-growing, encapsulated tumor of the anterior mediastinum with no tendency to recur after a complete surgical excision. Here, we report the case of an adult female who presented with progressive dyspnea of 2 months’ duration especially on lying down. Chest radiograph showed opacity occupying the entire left side. Computed tomography of the chest revealed a large mass on the left side with fat attenuation. Computed tomography-guided biopsy obtained was diagnosed as hyperplasic thymic tissue. The tumor was successfully removed surgically, and histopathological examination confirmed thymolipoma.
