An intramural radiolucent band in the stomach wall can be seen on abdominal radiographs of cats without concurrent clinical gastrointestinal signs. A retrospective study of cats with normal abdominal radiographs and computed tomography (CT) was performed to determine the prevalence of this finding. This gastric radiolucent band was seen in 13 of 37 (35%) radiographs. There was no relationship between age, weight and relative obesity and the presence of this radiolucent band. Using CT, an intramural hypoattenuating layer was detected in the stomach wall of four of 15 (27%) cats. The intramural radiolucent band was visible on the radiographs in all four of those cats. This radiographic and CT finding was histologically determined to be normal fat in the gastric submucosa in one cat cadaver.
