Renal leiomyoma with extensive cystic degeneration
10-15) For example, solid-pseudopapillary neoplasms often undergo massive cystic degeneration
, and mucinous cystic neoplasms (16) have a tendency to become infected and contain suppurative contents.
MR imaging of synovial sarcomas reveals a mosaic of mixed low, intermediate, and high signal intensity on T2-weighted images as a result of the admixture of solid components, cystic degeneration
