284 Wunderlich Syndrome - Case Report of a Surgical Emergency Due to Spontaneous Non-Traumatic Retroperitoneal Haemorrhage

A 42-year-old female with no other significant co-morbidities presented with complaints of sudden onset abdominal pain, she was in state of shock- her haemoglobin dropped drastically to 6.8g/dl from 11.8g/dl. She was resuscitated and was given blood transfusion. CT Scan was suggestive of retroperitoneal haemorrhage due to rupture of Renal angiomyolipoma (RAML). Patient underwent selective embolization of renal artery the next day and was discharged after 3 days of post-operative stay. Wunderlich Syndrome-is a rare condition in which spontaneous nontraumatic renal haemorrhage occurs into the subcapsular and perirenal spaces is most commonly caused due to spontaneous rupture of RAML.It is characterized by Lenk’s triad – Acute flank pain, flank mass, hypovolemic shock. Size of AML (>4 cm), prothrombotic states such as pregnancy are main causes of AML rupture. Patients are managed conservatively or with help of selective arterial embolization. Nephrectomy is last resort in a hemodynamically unstable patient or in cases of embolization failure. When dealing with acute abdomen with haemodynamic instability in non-traumatic cases it is essential to consider possibility of Wunderlich Syndrome. Early diagnosis, availability of Interventional radiology is key to successful management and potentially avoiding a Nephrectomy.
