Abstract
Purpose To demonstrate the value of CT lymphangiography to detect lymphatic leakage, especially at the thoracic level, prior to therapeutic intervention. Patients and methods Between 2004 and 2008, nine patients underwent lymphangiography, followed by CT for the evaluation of intractable lymphatic leakage in spite of optimal medical management. Patients included seven females and two males, with age ranging between 25 and 58 years. Lymphangiography was performed after unilateral or bilateral foot injection(s) of Lipiodol ultrafluid followed by standard radiographs of the chest and abdomen and CT of the chest, abdomen and pelvis. The images were reviewed by two experienced radiologists. Results Lipiodol leakage was observed in six patients, while three patients showed evidence of lymphangiectasia of the abdominal and/or thoracic lymphatics. Spontaneous resolution of leakage after lymphangiography occurred in three cases. Conclusion CT lymphangiography allows direct evaluation of lymphatics, from pelvis to chest, in order to detect the site of leakage at the origin of a chylous effusion and assist in its management.
