Diagnosis of Apple Core Lesion

Apple core lesions show up on tubular structures, such as intestines.

An apple core lesion appears when a mass narrows or encircles a tubular structure of the body, typically the bowel and sometimes the esophagus. These lesions usually are found during computer-assisted tomography (CAT) scans, a colonoscopy or a barium-contrast study. They take their name from the shape into which the bowel is compressed.

Causes

Apple core lesions usually are caused by cancer, mainly adenocarcinoma or lymphoma. They also can result from inflammatory disorders such as colitis, Crohn's disease or diverticulitis. Some infections can cause these lesions, as can tuberculosis.

Treatment

Because an apple core lesion is a symptom of an underlying disease or condition, treatment of the lesion depends on its cause. A doctor must diagnose the cause of the constriction, then resolve it so that the body can function normally.

Considerations

Anyone who experiences unexpected weight loss, especially accompanied by diarrhea or constipation, should consult a physician to determine the cause. If an apple core lesion is part of the diagnosis, its resolution may involve major surgery. Consult a licensed medical professional for diagnosis and treatment of any disease.
