Pediatric abdomen

Ultrasound images of pediatric abdomen:

Ectopic kidney or Renal ectopia:

1) Pelvic kidney in neonate:

This female neonate presented with imperforate anus. Sonography reveals normally located right kidney. However the left kidney is not visualized in left renal fossa. Ultrasound images reveal a pelvic kidney that appears somewhat rounded, located posterior and superior to the bladder. The renal pyramids of both kidneys appear echogenic suggestive of early nephrocalcinosis. The uterus of this neonate was not visualized well. Color doppler imaging shows the vascularity of the pelvic kidney. Images taken using a Toshiba Xario machine.

2) Nephrocalcinosis in neonates:

These ultrasound images of neonatal kidneys show- markedly echogenic renal pyramids, bilaterally, with chief involvement of the tips suggestive of medullary nephrocalcinosis. Such nephrocalcinosis in neonates usually follows long term parenteral therapy or due to use of certain drugs notably gentamicin and furosemide. It can also be caused by low fluid intake in the neonate and due to oxygen dependency. This condition, in neonates, usually resolves following correction of the etiological factors.
