Subcutaneous accumulation of lymphatic fluid usually results from disruption of lymph channels or outflow obstruction. The cause of chylothorax, a subset of this disorder, has been classified by DeMeester
1 into congenital, traumatic, diagnostic procedures (iatrogenic), and neoplastic categories. The primary imaging modalities to assess lymphocoeles are computed tomography and magnetic resonance imaging. Lymphoscintigraphy and lymphangiography are used occasionally to delineate the course of lymph flow. Isosulphan blue injection is used to aid in the localization of disrupted lymphatic channels during operative repair.
Treatment of groin and abdominal lymphocoeles consists of observation only, aspiration (often repeated), instillation of sclerosing agents, irradiation, and surgical closure-excision. Most cases of mediastinal lymphocoele can be attributed to iatrogenic
2 or accidental
3 trauma, although large cysts of the thoracic duct in the mediastinum have been reported without a clear cause.
4 Even less frequently, these cysts manifest themselves as a supraclavicular mass confined to or predominantly located in the neck.
5,6 Cysts of the right lymphatic system are extremely rare. Only one case of a mediastinal lymphocoele has been reported that was thought to arise from the right lymphatic system.
