CT

CT of the neck

Non-enhancing, tubular/multicystic, multicompartmental, water density structure extending from the left supraclavicular region and inferiorly to the left paraesophageal (posterior mediastinum) region to the level of the aortic arch. The lesion is displacing the sternocleidomastoid/internal jugular vein anteriorly and the trachea/esophagus to the right.

Case Discussion

This patient had long standing soft palpable mass in the left side of the neck. A neck CT with IV contrast was performed and the lesion was believed to be a lymphangioma. Subsequently, a non-contrast chest CT was performed and the tubular/cystic mass extended from the left neck to the posterior mediastinum and to the level of the cisterna chyli, consistent with a lymphocele of the thoracic duct.
