Presentation
Pelvic pain and chronic constipation.
Patient Data
A few subpleural fibrotic nodules are seen at lungs.
A 27 mm hyper dense mass is noted at third hepatic segment.
Marked asymmetric polypoid wall thickening is present at left side of rectum.
The fat planes between mass, uterus and left ovary are obliterated. There are a few small peri rectal lymphadenopathies. The mesorectal fascia is infiltrated by mass at left side.
Control CT in 6 mth after liver metastasectomy & rectal mass neoadjuvant chemoRx
A few small nodules, less than 5 mm are scattered at both lungs which seems to be fibrotic nodules.
Post-operative changes are seen at liver due to metastasectomy. There is no obvious hepatic mass in current study to suggest metastasis.
Mild increased wall thickness due to tumoral infiltration is present at mid and upper third rectum accompanied by perirectal fat stranding and a few regional lymphadenopathies. Fat planes between the rectal mass and posterior aspect of uterus are obliterated.
Case Discussion
Lacally advanced rectal mass (pathology proven cancer) with calcified liver metastasis (pathology proven).
Colorectal cancers can be found anywhere from the cecum to the rectum. Rectosigmoid involvement includes about 55% of cases as the most common site of colorectal cancer. CT is the modality most used for staging colorectal carcinoma, however, MRI is the preferred modality for the staging of rectal cancer.
