Abdominal computed tomography (<jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content>) revealed a cystic lesion accompanied by ring\u2010enhancement between the liver and right kidney with fluid collection in the pelvic cavity.

Transvaginal sonography revealed a pseudo\u2010gestational sac in a thickened endometrium. With a preoperative diagnosis of ectopic pregnancy at 7 weeks of gestation, laparotomy was performed. Following careful removal of clots between the liver and right kidney that contained a gestational sac, continuous bleeding from a defect in the <jats:styled-content style=\"fixed-case\">G<\/jats:styled-content>erota's fascia of the right kidney was noted. The postoperative course was uneventful and the serum <jats:styled-content style=\"fixed-case\">hCG<\/jats:styled-content> concentration decreased markedly.
