Eponyms in radiology of the digestive tract: historical perspectives and imaging appearances. Part I. Pharynx, esophagus, stomach, and intestine.

Eponyms serve as a means of honoring individuals who have made important discoveries and observations. Eponyms are frequently encountered in the field of radiology, particularly in radiology of the digestive tract. However, the use of eponyms may fail to convey a precise meaning or definition and could lead to miscommunication. Moreover, in some instances, more than one individual may have contributed to the discovery or description of a particular anatomic structure or disease, whereas in others, an eponym may have been incorrectly applied initially and propagated for years in the medical literature. Nevertheless, radiologic eponyms are a means of honoring those who have made lasting contributions to the field of radiology, and familiarity with these eponyms is important for proper reporting and accurate communication. In addition, the acquisition of some historical knowledge about those whose names are associated with various structures or pathologic conditions brings some humanity back into the science of medicine.
