Our work is about a 34-year-old woman with no particular history who was admitted for a cervical mass which showed a substantial increase in size in the last 8 months. Physical examination revealed a fluctuant and painless mass in the right posterior triangle which was tender on palpation. CT scan of the neck showed a multi-loculated homogeneous cystic lesion located primarily in the right posterior cervical triangle, and extending to the right deep cervical spaces, underneath an elevated sternocleidomastoid muscle. The right jugular vein, while relatively compressed, was still patent. There was no contrast enhancement after intravenous injection. The patient underwent complete surgical excision by transverse neck incision and the diagnosis of lymphangioma was confirmed on histological examination.
