Abstract
Spontaneous renal haemorrhage is a rare but severe condition known as Wunderlich syndrome (WS). The classic presentation includes sudden-onset flank pain, a palpable flank mass and hypovolaemic shock (Lenk's triad). WS can be due to neoplasms, vascular diseases, cystic rupture, coagulopathies and infections. A contrast-enhanced CT scan of the abdomen is mandatory for diagnosis. Surgery is reserved for haemodynamically unstable patients and those with neoplastic disease. We describe a case of WS in an anticoagulated patient with chronic atrial fibrillation, diabetes mellitus type 2 and hypertension, who developed acute renal failure and severe anaemia, that completely resolved with conservative treatment and discontinuation of anticoagulation therapy. LEARNING POINTS: Wunderlich syndrome refers to spontaneous renal or perinephric haemorrhage.Contrast-enhanced CT of the abdomen is the gold standard for diagnosis.Surgery should be reserved for haemodynamically unstable patients or those with neoplastic disease.
