Cystic lymphangioma of the colon: Endosonographic diagnosis with through-the-scope catheter miniprobe and determination of further management

Lymphangioma of the colon is rare. There are several reports that endoscopic ultrasound is useful for diagnosis of colonic lymphangioma. We report a case of lymphangioma of colon diagnosed by catheter endosonography and review the literature on endoscopic ultrasound in cystic lymphangioma of the gastrointestinal tract. A 70-year-old female was found to have two submucosal lesions in the colon by colonoscopy. Endoscopic ultrasound revealed that these lesions were anechoic, multicystic, and confined to the submucosa, and the underlying muscularis propria was intact. These findings were consistent with cystic lymphangioma. If typical endosonographic images of an anechoic, septated lesion within colonic submucosa are obtained, further workup or treatment may not be necessary if the patient is asymptomatic.
