Sister Mary Joseph nodule from metastatic renal cell carcinoma.
Metastatic lesions of the umbilicus are more common than primary malignancies and are commonly referred to as Sister Mary Joseph nodules. Most arise from the stomach or the female genital tract. We describe an unusual case of renal cell carcinoma with peritoneal implants producing a Sister Mary Joseph nodule diagnosed by CT. To our knowledge, no report of a urinary tract malignancy with umbilical involvement has been described in the radiological literature.
