Ultrasound images of retrocaecal appendix

Intratesticular varicocele




























































Intratesticular varicocele is the presence of a dilated vein within the testes, usually with coexisting extratesticular varicocele. In these nice ultrasound and color doppler images, Shlomo Gobi, Israel demonstrates an intratesticular varicocele of the left testes. The affected vessel (seen on color flow images) shows typical venous spectral flow pattern and reflux on Valsalva manoevre. The patient, in this case also had an extratesticular varicocele (not shown in these images). See the link: http://drjoea.googlepages.com/scrotum for more on this topic.
Also see: http://www.ultrasound-images.com/scrotum.htm for sonographic images and ultrasound case studies of the scrotum.
Images in this case are taken using an ATL HDI 3000 color doppler machine.

Ultrasound imaging in colitis:



This is a nice ultrasound image of colitis in a child. Observe the grossly thickened wall of the caecum and the associated mesenteric lymph node enlargement. This child also had other findings including round worm infestation and appendicitis.

See: http://www.ultrasound-images.com/colon.htm (for full case and more ultrasound images).

Gastric wall thickening















These ultrasound images of the stomach wall show considerable thickening of the pyloric wall (13 to 16 mm. thickness). Such thickening of stomach wall is seen in infiltrative lesions sucha s adenocarcinoma of the stomach and lymphoma. Images courtesy of Dr. Ravi Kadasne, UAE.

Focal fatty change of liver:



Focal fatty change of the liver is caused by the combined effect of steatosis with hepatic ischemia. This ultrasound image shows a typical focal fatty infiltration of the right lobe of liver. Note the absence of mass effect which distinguishes focal fatty change from other space occupying lesions of the liver. Image courtesy of Dr. ravi Kadasne, UAE. The ultrasound machine used here is the IU 22 from Philips.

Nephrocalcinosis

In this newest page of my gallery of ultrasound images, I have added some pictures of nephrocalcinosis in neonate. Check: http://www.ultrasound-images.com/ped-abdomen.htm
The images are self explanatory and show a relatively common problem in neonates following long term (weeks or months) of parenteral therapy besides certain medications. On another page, I describe the same disease in adults (see: http://www.ultrasound-images.com/renal-calculi.htm ). But it is in neonates that the pathology is so clearly evident on sonography, the reason being the better visualization of the pediatric abdomen and also the extent of involvement of the kidneys. In fact, it is often difficult to distinguish nephrocalcinosis from renal calculi, so dense is the extent of calcification.
