Discussion: CL should be considered as a differential in patients with multiple aggregated mucosal lesions that appear as polyps on endoscopy. Speculation on etiology has ranged from developmental (failure to establish connections to lymphatic drainage sites), or seen secondarily after trauma, prior surgeries, radiation, lymphatic obstruction possibly secondary to adjacent mass lesion, or previous inflammatory processes. Free intraperitoneal air may suggest impending clinical decline in such patients. Surgical resection is the treatment of choice in symptomatic patients.[1990] Figure 1.
