We report a patient who suffered from esophageal cancer that metastasized to the thyroid. There are only a handful of cases of esophageal cancer with metastases to the thyroid reported in the literature. To our knowledge, this is the first with a diffusely infiltrative pattern (the others were focal masses/nodules). This diffusely infiltrative pattern of metastatic disease is important for radiologists to be aware of because it is particularly difficult to detect and is not characteristically neoplastic by pattern. A diffuse parenchymal abnormality that is bilaterally symmetric is more commonly associated with non-neoplastic diffuse thyroid disease, such as autoimmune thyroid diseases (eg, Graves' disease). As such, in addition to the more common non-neoplastic differential diagnoses associated with diffuse thyroid disease, a diffuse thyroid parenchymal abnormality in a patient with a history of esophageal carcinoma should raise the question of diffuse metastatic infiltration. |
