Wunderlich's syndrome (spontaneous renal haemorrhage)

Wunderlich's syndrome is a rare condition characterised by spontaneous non-traumatic renal haemorrhage into the subcapsular and perirenal space. The commonest cause of Wunderlich's syndrome is renal neoplasms, with angiomyolipoma and renal cell carcinoma being the most common benign and malignant lesions, respectively. We report a case of Wunderlich's syndrome in a 46-year-old woman. She presented in the emergency department with the chief complaints of sudden onset of abdominal pain with no significant medical history. Imaging findings and clinical history led to the diagnosis of Wunderlich's syndrome. The patient underwent left partial nephrectomy and recovered without any complications. She is presently doing well.
