A Subacute Presentation of Wunderlich Syndrome in a Young Woman: A Case Report.

Wunderlich syndrome (WS) is a rare, potentially life-threatening medical condition characterized by spontaneous renal or perinephric hemorrhage occurring in the absence of known trauma. WS usually presents as Lenk's triad: acute flank pain, flank mass sensation, and hypovolemic shock; however, the presentation of this condition can vary in terms of symptom type and duration. We present the case of a 23-year-old previously healthy woman who consulted our emergency department with an unusual subacute form of presentation of WS (eight days of pain) due to an angiomyolipoma. Considering that the patient was clinically stable, a conservative approach with strict follow-up with serial computed tomography scans was taken.
