Wunderlich Syndrome due to Ruptured Pseudoaneurysm of Angiomyolipoma in First Trimester: A Rare Case Report.

Angiomyolipoma (AML) is a rare benign tumour of kidney which demonstrates rapid growth during pregnancy due to hormonal stimulation, leading to rupture. Majority of reported ruptured AMLs are in third trimester. We report a case of ruptured angiomyolipoma at 10th week of gestation, the earliest rupture known in singleton pregnancy. The AML had pseudo-aneurysm formation with extra-tumoural rupture during pregnancy, a finding never reported in literature yet. The patient had active bleeding with expanding peri-nephric haematoma during initial two days of conservative management. Hence, after counselling and taking prior informed written consent for Medical Termination of Pregnancy (MTP), computed tomography scan of abdomen with angiography followed by emergency coil embolization of the bleeding right upper polar segmental artery was done. After stabilization, MTP was done at 12th week of gestation. Counselling and consent for continuing or aborting the pregnancy is of utmost importance for best possible outcome for patient and foetus.
