[Subepithelial pelvic hematoma].

INTRODUCTION Subepithelial pelvic hematoma (Antopol Goldman lesion) is a rare condition that may clinical and radiologically simulate a renal or pelvic neoplasm and whose final diagnosis has been established after nephrectomy in most published cases. To avoid misdiagnosis, imaging tests and high diagnostic suspicion are essential. MATERIAL AND METHODS We present the case of a 43-year-old woman with no background of interest who was admitted to our Hospital complaining of acute left flank pain after a physical effort. The patient was studied by Ultrasonography, Computed Tomography and evolutively by Magnetic Resonance Imaging. RESULTS The radiologic exams showed a lesion in the left renal sinus with characteristics suggestive of subepithelial pelvic hematoma and without data revealing any underlying lesion. The patient was treated conservatively and follow-up examinations confirmed the disappearance of the lesion. CONCLUSION Knowledge of the radiologic features of Antopol Goldman lesion as well as a high degree of clinical suspicion are crucial in the management of patients affected by this uncommon condition and may avoid an unnecessary nephrectomy.
