Bilateral thoracic kidneys combined with inferior vena cava located behind the anterior abdominal wall: A case report and review of literature

Abstract

Ectopic thoracic kidneys are the rarest form of renal ectopia. Moreover, congenital abnormality of a primary anterior inferior vena cava (IVC) located behind the anterior abdominal wall is extremely rare. To date, only one such case has been reported. Herein, we report a rare case of a 55-year-old Chinese male with bilateral thoracic kidneys combined with an anterior IVC, a malformed liver, and a large-round-folds navel. The classification, clinical characteristics, and management options of a thoracic kidney was also summarized by literature review. To our best knowledge, the simultaneous detection of such multiple complex abnormalities has not been reported.

Bilateral subdiaphragmatic renal ectopia with associated congenital anomalies: a case report and systematic review of cases

“…Cephalad ectopic kidneys in intrathoracic or subdiaphragmatic locations may mimic mass or simulate pathology on chest radiographs [8][9][10]. To the best our knowledge, at the time of this writing, there were only ten reported cases of bilateral subdiaphragmatic renal ectopia, but none were associated with mesocardia [11][12][13][14][15]. In this article, we present a case of incidentally discovered bilateral subdiaphragmatic ectopic kidneys with abnormal shape of the liver, and spleen as well as association of mesocardia.…”
