This 24 year-old female patient presented for imaging for investigation of a possible thyroid nodule. Ultrasound showed a cystic lesion situated anterior to the sternocleidomastoid muscle. Close inspection revealed a sinus tract extending to a small skin lump immediately superior to the sternoclavicular joint. A subsequent CT showed a further tract extending proximally to the carotid bifurcation. The findings are characteristic of a second branchial cleft cyst.
