Branchial cleft cysts (BCC) are benign lesions caused by anomalous development of the branchial apparatus. This case report describes a 63-year-old woman with a 12 cm×12cm sized cystic mass located anterior to the manubrium sternum and sternum. MRI revealed a cystic lesion with a sinus tracking to the piriform sinus. Postoperative histopathological examination confirmed the diagnosis of branchial cleft cyst.
