Post-partum occurrence of Wunderlich syndrome and microangiopathic haemolytic anaemia (MAHA): a case report

Abstract

This is a case of a 27-year-old primigravida with monochorionic diamniotic twin gestation who was admitted to the hospital for induction of labour. Her postpartum course was complicated by microangiopathic haemolytic anemia (MAHA). The etiology for the MAHA was initially thought to be secondary to pre-eclampsia and vitamin B12/folate deficiency. However, she had persistent anemia and further workup demonstrated that she had a left renal cell carcinoma (RCC) with perinephric haemorrhage consistent with Wunderlich syndrome. This case was intriguing because of its unusual presentation and the several diagnostic and therapeutic challenges along the way. Abbreviations: MAHA: microangiopathic haemolytic anaemia; RCC: renal cell carcinoma; BP: blood pressure; WS: Wunderlich syndrome; CT: computed tomography; LFTs: liver function tests; LDH: lactate dehydrogenase; HELLP: haemolysis elevated liver enzymes, low platelets; DIC: disseminated intravascular coagulation; PLASMIC: score for TTP – includes platelet count 2.5%, haptoglobin undetectable, or indirect bilirubin >2mg/dL), active cancer, history of solid organ transplant, mean corpuscular volume (MCV) 6; TTP: thrombotic thrombocytopenic purpura; APLA- anti-phophospholipid antibody; BMI: body mass index; TMAs: thrombotic microangiopathies; HUS: haemolytic uremic syndrome; vWF: von Willebrand factor
