Presentation
Abdominal pain and constipation
Patient Data
A short segment of irregular mural thickening (due to tumoral infiltration) with subsequent luminal attenuation is present at the proximal transverse colon, measuring 6 cm in length and 3 cm in maximal thickness; accompanied by pericolic fat stranding and few regional lymphadenopathies with SAD less than 8 mm. No free intra or retroperitoneal air or fluid could be detected.
Hiatus hernia also noted.
Case Discussion
Non-obstructing colonic adenocarcinoma of the proximal transverse colon with few small peritumoral lymph nodes without metastases elsewhere in the abdomen or pelvis.
Colorectal cancers can be found anywhere from the cecum to the rectum and transverse colon involvement includes about 10% of cases 1.
CT is an excellent modality for evaluating colonic masses, assessing associated lymph node status and for metastatic workup as well.
