Chylothorax development following blunt abdominal trauma is a rare event. While low volume chylothoraxes usually improve with conservative treatment, invasive interventions are required in high-volume chylothoraxes with daily drainage exceeding 1000 ml. We report a case of a 14-year-old boy who developed high-volume (>3 L/d) chylothorax on the left side following blunt abdominal trauma. The patient did not respond to conservative treatments. He underwent thoracic duct ligation three times, with percutaneous lymphatic interventions, and percutaneous Lipiodol-glue mixture injections under computed tomography (CT) guidance, but all treatments were unsuccessful. We describe the four-month multidisciplinary challenge in this case that was ultimately successfully treated by surgical ligation of aberrant and/or collateral lymphatics draining from the left abdomen to the left pleural cavity, with the help of the novel cone-beam computed tomography (CBCT) lymphangiography (LAG) technique.
