“…More common involvement of the distal small bowel is not likely to be the result of prominent lymphatic tissue since secondary gastrointestinal spread is hematogenous. The large intestine is the least common site of gastrointestinal organs affected with hematogenous secondary melanoma (8)(9)(10). In one series of 2500 cutaneous melanomas, only one percent exhibited postmortem colonic deposits (13).…”

In 10 patients with gastrointestinal metastases from cutaneous malignant melanoma, metastases to the stomach were found in 2, the small bowel in 9, and the large bowel in 3. Gastric metastases typically appeared as target lesions. However, the morphology of secondary melanoma deposits to the small and large intestine varied significantly, target lesions being only one possible manifestation. Less common appearances of gut metastases were found in 4 patients. One presented atypically with matted loops of distal ileum resulting in prolonged stasis of barium in the affected areas. In 3 patients, infiltrative and stenotic lesions were found in the distal ileum, terminal ileum and cecum. One stenotic lesion of the distal ileum was accompanied by multiple small polypoid lesions more proximally, and the cecal lesion was ulcerated. Six of the patients presented with polypoid and, occasionally, ulcerated and multiple secondary melanoma deposits. Possible causes for variations in morphology are discussed.

“…The majority of gastrointestinal metastatic lesions have been previously described as submucosal, mucosal or, less frequently, near serosal deposits (3,8). Polypoid lesions, often with a central collection of barium in an ulcer or epithelialized umbilication, result in a 'bull's eye' or 'target' appearance as the most constant finding (4,12,15).…”

Secondary involvement of the transverse colon by tumors of the pelvis: Spread of malignancies along the greater omentum

Based on selected case studies the pathways of spread of malignancies arising from the pelvis are discussed. Secondary involvement of the transverse colon with characteristic lesions at the inferior border may be seen in these cases, caused by metastatic spread via the greater omentum. Ultrasonography and computed tomography may prove this diagnosis by showing peritoneal metastatic spread and tumorous infiltration of the greater omentum.

“…3). This appearance has been termed variously "traction change" (H.M. Goldstein, personal communication) "tethering" [1] "pleating" and "spiculation" [2]. Perhaps traction change is the most specific term since it connotes that the serosa is "tied down," prohibiting bowel distension and focally pleating the mucosa.…”

Radiographic manifestations of extrinsic processes involving the bowel

Extrinsic processes affecting the bowel are frequently mistaken for intrinsic gastrointestinal disease. However, extrinsic involvement of bowel produces morphologic changes distinguishable from those of primary diseases of bowel in most cases. These changes include (a) an intact mucosal surface, (b) mass effect, (c) fixation and angulation mucosal folds, (d) fixation and angulation of bowel loops, and (e) luminal constriction. The extrinsic process involving bowel most often encountered on barium studies is metastatic neoplasm; other causes are inflammatory disease, adhesions, and endometriosis. Although the radiographic manifestations of extrinsic processes affecting bowel are nonspecific, when correlated with clinical information they may permit an astute diagnosis.
