Total body I-131 scanning done on a 67-year-old woman with thyroid cancer revealed abnormal tracer uptake within the mid-thorax, thought to represent metastasis in the mediastinum or thoracic spine. Single-photon emission computed tomography images of the thorax showed contiguity between the thoracic uptake and the normal, physiologic uptake of radioiodine in the stomach, suggesting physiologic accumulation within a hiatal hernia. To confirm the alimentary tract location of the radioiodine, a study using orally administered Tc-99m SC in water was performed. The images were similar to the iodine images and revealed a pattern consistent with hiatal hernia. A hiatal hernia was also observed as ..View full abstract
