Week 2 abdominal ultrasound

Portal veins have more hyperechoic walls than hepatic veins

When viewing the liver on an ultrasound, what vessels will have echogenic walls and what vessels will have similar echogenicity to that of the liver?

Spleen

Which organ on an ultrasound is more hyperechoic: the spleen or the liver?

Gall bladder sludge

What hyper echoic material (when compared to the rest of the gallbladder lumen) can often be found in the gallbladder?

cats

Which species is a bilobed gall bladder common?

Hepatomegaly

What can be said about the liver if it fully encompasses the right kidney?

Lipidosis, lymphoma, or cirrhosis

What are some reasons as to why the liver could have an increased echogenicity when compared to the spleen?

Acute hepatitis and passive congestion. Will see inc echogenicity of hepatic vessels

What are some causes to hypo-genicity of the liver and what are some ultrasound findings?

Homogenous and of a fine echo texture

How can you one describe the echogenicity of the parenchyma of the liver?

Multiple hypo echoic nodules

What could cause the spleen to have a Swiss cheese appearance on an ultrasound?

The medulla is more hypo echoic compared to the cortex

What is the echogenicity of the renal medulla compared to the cortex?

Acute renal failure often secondary to ethylene glycol toxicity

A thick hyper echoic cortex of a kidney on an ultrasound could indicate what?

Leptospirosis/ acute interstitial nephritis

An increase in echogenicity and size of the kidney could be caused by which disease?

Polycystic kidney disease

Multiple anechoic structures occupying the renal cortex can indicate what?

Hydronephrosis

A dilated renal pelvis with an anechoic fluid that can cause renomegaly is termed what?

Lumen/mucosa interface -hyper

Mucosa- hypo

Submucosa- hyper

Muscularis- Hypo

Serosa- hyper

When looking at a ultrasound of small intestinal loops, what are the differing layers from center to outer and their echogenicities?

Rugal folds

When looking at an ultrasound, what are internal structures that can confirm the stomach is in view?

bullseye

What shape does intussusception of the bowel often take the shape of on an ultra sound?

Liver

What organ is most prominent in this ultrasound?

Bilobed gall bladder

What organ is this?

Left gall bladder

Right liver

What organs are marked?

Portal veins

What structure is the yellow arrow pointing to ?

Left liver more hypoechoic

Right spleen more hyper echoic

What organs are labeled here and what is their echogenic pattern?

Hepatomegaly

What anomalies are occurring in this kidney

Polycystic kidney disease

What is occurring in this patient?

Hydronephrosis

What is this arrow pointing to?

Stomach

what organ is prominent in this ultrasound?

Small intestine

Organ?

Intussusception of the small intestine

What anomaly are these arrows pointing to?

TCC

What is being depicted here?

Polyp in the bladder

What are that?
