title: Papillary renal cell carcinoma in allograft kidney.
abstract: Papillary renal cell carcinoma is a subgroup of malignant renal epithelial neoplasms. Its occurrence in allograft transplanted kidney has not been debated in the literature. We report two pathologically proven cases and discuss the clinical hypothesis for such neoplasms and the aspect on MR images. The paramagnetic effect of the iron associated with an absence of signal coming from calcifications is a plausible explanation for this unusual hypo-intense appearance on T2-weighted sequence.
