title: [Subepithelial hemorrhage of renal pelvis (Antopol-Goldman lesion). Report of 4 cases and review of the literature].
abstract: OBJECTIVE
  The subepithelial hematoma of renal pelvis (Lesion of Antopol-Goldman) is a rare entity that preferably is diagnosed clinically as a neoplasic lesion.
  
  
  METHODS
  We present four new cases of subepithelial hematoma of renal pelvis diagnosed in our hospital from 1989.
  
  
  RESULTS
  Our cases presented clinically with hematuria and flanc pain, preferably in the left side (3 out of 4). After nephrectomy, all the cases showed a subepithelial hematoma of variable extension that can occupy the renal pelvis and calices, associated to hidronefrosis, cortical infartion, renomegaly or renal angioma. Additionally, two of our patients presented with dilation of the pielocalicial system, and a third one presented with urotelial carcinoma of the ureter, being therefore the lesion of Antopol-Goldman an incidental discovery. In the remaining case, the presence of multiple renal hemangiomas was identified as cause of the renal pelvic hematoma.
  
  
  CONCLUSIONS
  The preoperatore diagnosis of the lesion of Antopol-Goldman is difficult although it should be included as differential diagnosis in those cases with hematuria and alterations of renal pelvis in the image techniques, because an early diagnosis could imply a conservative treatment with pieloplastia or partial nephrectomy.
