Difficoltà interpretative alla TAC e alla RMN nella diagnostica differenziale della fibrosi retroperitoneale dal linfoma

Abstract

Retroperitoneal fibrosis (RF) often presents with characteristic clinical and urographic findings that may hide lymphoma. A case of RF with bioptic confirmation is reported. On CT examination the variations in enhancement were not useful in distinguishing RF from lymphoma. Although on sagittal and coronal images MR accurately depicted the extent of the abnormal retroperitoneal mass as found at surgery, it was not able to correlate heterogeneous low intensity T2-weighted signals with definitive histological features.
