Sonography of the stomach revealed a linear echogenic structure with posterior acoustic shadowing. On changing the probe angle the edge appears to be a semicircle. Plain X-ray of the abdomen revealed the structure to be coin (seen edge-on in the left hypochondrium). Images courtesy of Dr. Ravi Kadasne, UAE.

Here are the follow-up ultrasound scan and X-ray images of this patient, a young child. The coin, seen in the stomach (above images) has reached the caecum. (Images courtesy Dr. Ravi Kadasne).

2) Hypertrophic pyloric stenosis:

nipple sign of hypertrophic pyloric stenosis

This neonate underwent sonography for persistent vomitting. Ultrasound images reveal a) marked thickening of the wall of the pyloric canal (5.5 mm.) b) elongation of the of the pyloric canal (the cervix sign) c) shifting of the pylorus bringing it in close proximity to the right kidney (antero-medial to right kidney) and gall bladder. d) distended stomach e) mucosal prolapse producing the antral nipple sign is also seen.

These ultrasound images thus suggest a diagnosis of hypertrophic pyloric stenosis. Sonographic images courtesy of Dr. V. Ganesan, Bahrain. Images taken using a Philips IU22 ultrasound machine.
