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.

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.

An update of the newest additions to my website

Dear readers,

Just added a nice case, of pelvic kidney in a neonate at: http://www.ultrasound-images.com/ped-abdomen.htm The child had an imperforate anus with suspected recto-uterine fistula. Placed the high resolution ultrasound probe on the pelvis and saw a pelvic kidney, the left kidney not being seen in the left renal fossa. A clear example of renal ectopia! I have added 7 ultrasound images for this case of pelvic kidney at the link above. This page is freshly created and devoted to pediatric abdomen. What was interesting was that the pelvic kidney appeared round or oval in shape, suggestive of some degree of malrotation of the renal axis.

Gall bladder sludge in neonate:

These ultrasound images of a neonatal abdomen show a large amount of dense sludge in the gall bladder. Such sludge formation in neonates is often seen following parenteral nutrition and is usually self resolving.

Visit the page: http://www.ultrasound-images.com/pediatric.htm for ultrasound images of pediatric and neonatal diseases. At present I have added a few cases of neonatal intracranial/ germinal matrix hemorrhage and its complications, notably porencephaly. There is also a nice case of inguinal hernia containing ovary.

A web page of ultrasound images of renal calculi (kidney stones)

Just added some great images of renal calculi (commonly known as kidney stones)..from the usual to the unusual staghorn calculi. Just visit: http://www.ultrasound-images.com/renal-calculi.htm Staghorn calculi or triple phosphate calculi can be silent until they reach phenomenal proportions like this calculus which occupied half of the kidney. Luckily, in the case described at the link above, there was only mild hydronephrosis of the affected kidney.

Multinodular goiter

These ultrasound images of a middle aged female patient reveal: a) multiple solid nodules of varying sizes in both lobes of the thyroid gland b) coarsening of the echotexture of the thyroid gland c) cystic lesions scattered throughout the gland d) diffuse increase in size of the thyroid.

e) color doppler imaging reveals moderate augmentation of the vascularity of the thyroid. These findings suggest multinodular goiter of the thyroid. For more ultrasound images of thyroid pathology, visit: http://www.ultrasound-images.com/thyroid.htm

Cystic lesions of the thyroid

Thyroid cyst with nodule within it:
























Ultrasound images of the thyroid revealed a large cystic lesion with an irregular solid nodule along the margin of the cyst. Doppler imaging shows absence of significant vascularity in the nodule. This means that the nodule may be formed by debris within the cystic mass, typically seen in colloid cysts of the thyroid.

Ultrasound images of retrosternal goiter

Xray images show a large rounded opacity in the upper mediastinum.















































Ultrasound images of the thyroid show a huge gland, with inhomogenous appearance and calcification, extending to the retrosternal region. The thyroid measures more than 5 x 8 cms. These images by Mr. Shlomo Gobi of Israel were taken using the endocavity probe to better visualize the retrosternal extension of the thyroid goiter. Xray images show the goiter in the retrosternal region. You can view more such intersting ultrasound images of thyroid diseases at:

Interesting ultrasound images of the thyroid:

I have added some really nice sonographic images of the thyroid in my ultrasound image gallery.
See: http://www.ultrasound-images.com/thyroid.htm Among the cases (and ultrasound pictures) I have discussed here are: 1) multinodular goitre 2) Hashimoto's thyroiditis 3) thyrotoxicosis 4) hemithyroidectomy 5) sublingual thyroid. The last is a rare enitity and I have added 6 high res. images of this lesion.
Hashimoto's thyroiditis is a common condition that afflicts a large percentage of the populace here in S. India.

Endometrial hyperplaisa in a child

These ultrasound images of the uterus in a 12 yr. old female child with intermittent bleeding per vagina reveal- a) markedly thickened endometrium (3.3 cms). b) color doppler images reveal vascularity within the thickened endometrium. These images suggest endometrial hyperplasia (benign) in a child. The cause is presumably, increased oestrogen activity. Images courtesy of Dr. Richa Dikshit, India.
