Renal angiomyolipoma rupture in the immediate postoperative period following caesarean section

Abstract

Renal angiomyolipoma (rAML) is a rare benign tumour primarily affecting women due to hormonal influences, with accelerated growth observed during pregnancy. This case report presents a multigravida woman in her mid-20s at 37 weeks of gestation with stable vital signs and normal physical examination findings, except for swelling in the lower extremities. Following caesarean section delivery, she developed flank pain and haematuria in the immediate postoperative period. Emergency surgery revealed a ruptured rAML, resulting in unstable haemodynamics and significant blood loss. A multidisciplinary team performed a left radical nephrectomy to control bleeding. The patient required transfusions, ventilation and postoperative antibiotic therapy. This case underscores the importance of considering rAML rupture in the immediate postoperative period following caesarean section, highlighting the need for prompt evaluation in pregnant women with a history of urologic disorders.
