Presentation
Metastatic colorectal cancer. Ascites and acute renal failure.
Patient Data
Patient has renal failure...
Patient has renal failure thus no IV C+ administered.
Extensive metastatic disease including peritoneal tumor and ascites, but no liver metastases. Para-aortic lymphadenopathy with punctate calcification as well as left groin nodes and lung lesions that are calcified (arrows). Obstruction to the left ureter by nodes at least partly explaining the renal failure.
Case Discussion
Mucinous tumors (especially gastro-intestinal) are associated with punctate calcification and this can sometimes be used to identify the primary site. In this case some areas of tumor have calcified, including lung whilst others show no calcification.
