99m Tc-sulphur colloid Lymphoscintigraphy and SPECT/ CT in multiple primary lung cancer with chylothorax twice postoperatively

Chylothorax is an uncommon complication of thoracic surgery, which is characterized by accumulation of chylous lymphatic fluid in the pleural cavity. Single-photon emission computed tomography with computed tomography (SPECT/CT) technology has evolved for evaluating chylothorax in recent years (1,2). Multiple primary lung cancer (MPLC) refers to two or more primary cancers in different sites of one or both lungs and can be classified as synchronous or metachronous (3,4). We herein report for the first time a rare case of synchronous MPLC with two chylothoraxes.
