Imaging Misdiagnosis Analysis of a Rare Case of Renal Subcapsular Hematoma Located in the Renal Hilum and Collecting Area

Abstract

We report a rare case of renal subcapsular hematoma, which was located in the renal hilum and collecting area. Preoperative ultrasonography, retrograde urethrography, and computed tomographic examinations misdiagnosed the patient with simple hydronephrosis, without finding a lesion causing the hydronephrosis. We retrospectively summarized the imaging features and analyzed the reasons leading to the misdiagnosis.
