Acute presentation of Wunderlich syndrome in a pregnant woman treated with supra-selective cannulation of renal segmental arteries and nephrectomy: A case report

Abstract

ABSTRACT Wunderlich syndrome is characterized by the presence of abdominal pain, hematuria, and hypovolemic shock. We report a rare case of a 25-year-old pregnant woman, who came to the emergency department due to the sudden onset of low back pain and diaphoresis. The patient, during medical evaluation, experienced an altered state of consciousness. Diagnosed with hypovolemic shock, she was admitted to the operating room, where examination of the abdominal cavity revealed a left retroperitoneal hematoma. Damage control surgery was performed, but given the postoperative clinical deterioration, computerized tomography angiography of the abdomen was performed, showing a mass-like lesion arising from the upper pole of the left kidney, consistent with Wunderlich syndrome. Left nephrectomy was the definitive treatment for the 10-cm renal angiomyolipoma. Since Wunderlich syndrome is a potentially lethal entity, CT is usually the preferred diagnostic approach, and supra-selective vascular embolization is the first-line treatment.
