Renal medullary carcinoma: CT and MRI features.

OBJECTIVE

We review the cross-sectional imaging findings of six cases of pathologically proven renal medullary carcinoma in patients with sickle cell trait. MRI findings were available in three of the patients. To our knowledge, only one previous report has addressed MRI features of this rare disease.

CONCLUSION

In young patients with sickle cell trait, an infiltrative renal mass with associated retroperitoneal adenopathy and caliectasis are characteristic findings of renal medullary carcinoma on CT and MRI.
