Papillary Renal Cell Carcinoma with Extensive Paraaortic Nodal Metastasis Mimicking Malignant Lymphoma

Abstract: A 52-year-old woman with abdominal distension underwent computed tomography (CT) that demonstrated extensive paraaortic lymphadenopathy and a right renal mass. Compared to the renal cortex, the lesions exhibited low signal intensity on T 1 -and T 2 -weighted images and high intensity on diŠusion-weighted magnetic resonance (MR) images. We suspected malignant lymphoma and performed excisional biopsy, which revealed metastatic papillary renal cell carcinoma. Retrospectively, signiˆcantly reduced signal on in-pha… Show more

“…That is, when water and iron coexist within the voxel, signal intensity of IP should be smaller than that of OP due to the susceptibility effect of iron on IP. Therefore, when the signal on the subtraction image is lower than that of the normal lung tissue, the presence of iron or hemorrhage is strongly suggested [13], [14], as confirmed for the torsed ELS (infarcted lung tissue) in our case.…”
