Subdiaphragmatic Renal Ectopia: Case Report and Review of the Literature

Abstract EN

Background.

We report the case of a male infant whose right kidney migrated to an ectopic position after birth.

The migration of a kidney in postnatal life without any symptoms has not been reported in literature so far.

Case Presentation.

In a series of antenatal and the first postnatal ultrasound scans, the right kidney was normally located within the right renal fossa.

During the first 3 months of life, the kidney migrated to a subdiaphragmatic position.

This was confirmed on MRI scan.

The infant was asymptomatic with normal renal function and blood pressure.

Conclusion.

Postnatal migration of a kidney has been described in cases of diaphragmatic hernia or nephroptosis.

In this report, we describe a case of kidney migration where there were no underlying anatomical defects to provide an explanation for the kidney migration.

This is the first report in literature of a case of postnatal migration of a kidney.
