title: Imaging Appearances of Paratesticular Fibrous Pseudotumor.
abstract: BACKGROUND
  In this paper the clinical and radiological features of three cases with paratesticular fibrous pseudotumor were presented after a retrospective analysis of medical archives of our hospital.
  
  
  METHODS
  Each of the three cases had unilateral, multiple nodular lesions with smooth borders accompanied by a hydrocele. On sonographic examination, the lesions showed echogenicity similar to, or slightly lower than, the testis, and the two large lesions had posterior acoustic shadowing. Color Doppler ultrasound examination of two cases showed intralesional vascularity of mild-to-moderate degree. All lesions appeared hypointense compared to testicular tissue on T1W and T2W magnetic resonance images. Moderate-to-high enhancement was observed in the diffuse pattern after intravenous injection of contrast material. An intraoperative pathological examination was performed and local excision carried out in all three cases.
  
  
  CONCLUSIONS
  Fibrous pseudotumor is a rare benign paratesticular lesion, which can be confused with malignant masses. Imaging procedures play an important role in correct diagnosis. Unfamiliarity with imaging findings of paratesticular fibrous pseudotumor may eventuate in an unnecessary orchiectomy.
