Urinary Infection and Spontaneous Subcapsular Renal Hematoma

摘要

Spontaneous subcapsular renal hematoma is an uncommon entity. We report a 54-year-old lady presenting with high fever, dysuria followed 5 days later by acute onset left flank pain and uncontrolled hypertension. Ultrasound, computed tomography and magnetic resonance imaging showed a subcapsular hematoma in the left kidney. Except urinary tract infection and hypertension, no particular cause for the condition could be found. Symptoms and size of the collection decreased on conservative treatment. The collection disappeared on MRI at 6 weeks follow-up. She was asymptomatic at 23 months follow-up.
