Abstract

Because sentinel lymph nodes (SLNs) of esophageal cancer can be widely located between the neck and the upper abdomen, lymphoscintigraphy plays an important role in their detection, but some modifications are required to clearly visualize their locations. Recently, we applied the stereoscopic imaging method by adding the 10-degree oblique view to the conventional lymphoscintigraphy for SLNs, so that we could better determine SLN locations on the basis of depth information. In this report, we describe a case in which the oblique view of the lymphoscintigram contributed to improving the visualization of a mediastinal SLN of esophageal cancer. Evaluation of the patient's chest CT image validated the notion that gamma rays from SLN are less absorbed by the surrounding soft tissues and the sternum in acquisition from the oblique view than from the true anterior view. The additional oblique view of the lymphoscintigram is useful for evaluation of the SLNs of esophageal cancer.
