Cameron lesions

Last revised by Calum Worsley on 30 Nov 2021

Cameron lesions refer to linear ulcers or erosions that occur on the mucosal folds at the diaphragmatic impression of a hiatus hernia. They are usually radiographically occult and diagnosed endoscopically (although still useful for a radiologist to know).


Their prevalence has been reported in up to 5% of patients with a hiatus hernia who undergo esophagogastroduodenoscopy.

Clinical presentation

They can be associated with overt gastrointestinal bleeding or anemia


They are thought to occur due to vascular compression by the diaphragm from a large sliding hiatus hernia. 


They mostly tend to be located at the neck of a hiatus hernia.
