Colorectal Cancer Case Study 02
PET/CT FINDINGS: There were seven focal areas of abnormal intense increased uptake corresponding to soft tissue abnormalities in the abdomen and pelvis. In addition, a cystic area in the right ovary that was seen on the CT portion of the scan, showed a mural nodule which had moderate uptake of radiopharmaceutical on the PET portion. There was no other abnormal uptake identified in the chest or rest of the visualized body.
In this patient with colorectal cancer, small recurrent disease was easily identified and correctly localized utilizing PET/CT. Although PET/CT cannot detect microscopic disease, it is very good for finding small mesenteric implants that might be easily missed on CT alone. This patient was subsequently treated with chemotherapy without even having a biopsy to confirm recurrence because of the rising CEA levels and convincing imaging findings.
