We describe the case of chylothorax after esophagectomy for esophageal carcinoma. Lymphoscintigraphy with Tc-99m-human serum albumin-diethylenetriaminepentaacetic acid showed an abnormal radioisotope accumulation on the left side of the thoracic duct. Single-photon emission computed tomography (SPECT) combined with computed tomography (CT) revealed a hot spot directly on the site at, which the thoracic duct was ligated during surgery, which was the suggested site of chyle leakage. We emphasize that lymphoscintigraphy with SPECT/CT is very useful tool for accurately identifying the site of the chyle leakage.
