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.
