title: [A case of papillary renal cell carcinoma with abnormal vascularity revealed by pharmacoangiography].
abstract: A 64-year-old man with a right renal mass was referred to our hospital for further examination. The tumor demonstrated no dye enhancement of the computerized tomography (CT) scan. The tumor appeared as a low signal intensity image on the T1 weighted magnetic resonance imaging (MRI) and as a high signal intensity image on the T2 weighted MRI. Angiography revealed as hypovascular mass, however, the vessels in the tumor appeared on pharmacoangiography due to the absence of vasconstrictive response. A right radical nephrectomy was thus performed. The tumor was mostly necrotic and had a thick capsule. The histopathological findings indicated the tumor to be papillary adenocarcinoma.
