AB  - Perinephric myxoid pseudotumor of fat (PMPF) is an unusual clinical entity with 
      few prior imaging case reports. We report a multimodality imaging case series of 
      PMPF, consisting of four cases seen in our department with both imaging studies 
      and histopathologic confirmation. Three of the four patients had a history of 
      advanced non-neoplastic renal disease. The perirenal masses in these cases varied 
      in size and appearance. Some lesions resembled cysts or contained macroscopic 
      fat. Enhancement was equivocal on CT, but prominent in one case on MRI and in 
      another on contrast-enhanced ultrasound. Although not known to be malignant, PMPF 
      may be confused for a cyst, liposarcoma, or hypovascular solid neoplasm on 
      imaging. The dominant mass was resected in two cases because of concern for 
      malignancy, while percutaneous CT-guided biopsy was performed in the other two. 
      Mouse double minute 2 (MDM2) gene amplification by fluorescence in situ 
      hybridization (FISH) was negative in all four cases, excluding 
      well-differentiated liposarcoma. Radiologists should be familiar with PMPF to 
      provide appropriate guidance on clinical management.
