Patient originally presented with right upper quadrant to mid epigastric pain with jaundice. An obstructing mass can be seen at the head of the pancreas along with intra-heaptic and extra-hepatic duct dilation. The “candy cane” appearing structure is the dilated cystic duct with spiral valves of Heister visible.

An elderly patient presented with abdominal pain and hypotension. On eval of liver a linear intrahepatic hyperechoic area was seem consistent with hepatic artery calcification.

Pneumobilia and portal venous gas would be include in differentials however pneumobilia would present with air more centrally while portal venous gas would be more peripherally.

Here is an example of pneumobilia.

51 year old male with a chief complaint of RUQ abdominal pain for 3 days with nausea and vomiting. When looking to evaluate the aorta, IVC or gallbladder and you find multiple anechoic structures you can you use color doppler to help determine which structures have pulsatile blood flow, non-pulsatile or no flow in a effort to distinguish these anatomic structures.

A 50-year-old male presented with right upper quadrant pain, vomiting, and fever. A point-of-care ultrasound demonstrated a large, approximately 20cm heterogenous, well-demarcated mass in the liver. CT scan confirmed the presence of an abscess. IR-guided drainage yielded "anchovy paste" purulent aspirate, which later grew out Entamoeba histolytica. Amebic liver abscesses are the most common form of extra-intestinal amebiasis, but abscesses can also form in the lung and brain. He was treated with metronidazole without complications.

Elderly male with history HTN, DM presented with jaundice and elevated LFTs, bilirubin, and alkaline phosphatase. POCUS showed distended gallbladder with normal wall thickness, and some areas of increased echogenicity in the gallbladder which may represent debris. Patient was later found to have a proximal pancreatic mass likely compressing bile ducts and causing distention of gallbladder and elevated lab findings.

An elderly female presented to the emergency department reporting abdominal pain. POCUS seen here revealed the presence of a gallstone within her gallbladder with shadowing; and a notable absence of findings consistent with cholecystitis including gallbladder sludge, wall thickening, and/or ductal dilatation. This enabled appropriate triage of this patient to outpatient follow-up rather than considering immediate surgical intervention.

A middle aged patient presented with epigastric pain and vomiting. Ultrasound identified anechoic cystic thickening of the gallbladder wall associated with comet-tail artifact and twinkling artifact. Findings were consistent with adenomyomatosis, a generally benign condition caused by hyperplastic growth of the gallbladder mucosa often associated with chronic inflammation.

Often, a left lateral position delivers a clear image of the common bile duct (CBD) on its entire length, as is the case in this clip. Notice the normal hyperechoic walls and its small diameter. The CBD inner wall diameter should be < 6 mm in healthy adults, although it can be enlarged in post-cholecystectomy patients.

Dr. Felipe Urriola P. Emergency Unit, Puerto Aysen Hospital. Chilean Patagonia.

The large, pulsatile inferior vena cava lies at the bottom of the screen. Anterior to it and from left to right we see the large portal vein and small, round hepatic artery. Just above the hepatic artery lies another tubular structure which presents hyperechoic walls and an anechoic lumen; this is the common bile duct.

Dr. Felipe Urriola P. Emergency Unit, Puerto Aysen Hospital. Chilean Patagonia.

Both the adjustment of depth and color-doppler allow for better identification of structures. The large, pulsatile inferior vena cava lies at the bottom of the screen. Color-doppler helps to discern blood vessels from other anatomical structures. Anterior to the IVC and from left to right of the screen, we can see the portal vein and hepatic artery with color-flow. Just above the hepatic artery lies another tubular structure which presents hyperechoic walls and an anechoic lumen; this is the common bile duct.

Dr. Felipe Urriola P. Emergency Unit, Puerto Aysen Hospital. Chilean Patagonia.

A patient presented with RUQ abdominal pain.

Ultrasound showed cholelithiasis and choledocholithiasis. Left image shows a portion of the common bile duct containing a small hyperechoic shadowing mobile stone. Right image shows the same with color Doppler added demonstrating twinkling artifact.

Learning point: Twinkling artifact is most often associated with urinary stones but also can be caused by gallstones (depending on composition), bowel gas, foley balloons, metallic objects, and many others. Twinkling artifact may help identify small stones that do not cause prominent acoustic shadowing.

A 40-year-old male presented to the ED with several week hx unintentional weight loss and new onset jaundice. POCUS of his RUQ demonstrated an overtly distended gallbladder with plethoric intra-hepatic circulation causing compression of the right kidney. As expected, he had laboratory evidence of an elevated direct bili and acute kidney injury. Subsequent MRI confirmed the diagnosis of cholangiocarcinoma.

A 33-year-old female presented to the ED reporting acute onset abdominal pain immediately after eating a meal. She was well-appearing and afebrile; physical exam notable for reproducible tenderness to palpation of her upper abdomen. POCUS long axis view obtained to right of epigastrium notable for hyperechoic material within the lumen of the gallbladder (anechoic) producing posterior shadowing. This confirmed our clinical suspicion of biliary colic, and the patient was able to be discharged with scheduled outpatient elective surgery.

Adenomyomatosis is a generally benign condition characterized by diffuse thickening of the gallbladder wall and intramural diverticula. On ultrasound it creates comet tail artifacts (reverberation artifacts that appear as tiny echogenic beams) originating from distinct locations on the gallbladder wall. 

This is often seen in asymptomatic patients; however it can be associated with chronic inflammation from gallstones and pancreatitis. 

Dr. Lindsay Davis - NYU/Bellevue Department of Emergency Medicine

Two large, hyperechoic stones can be appreciated in this gallbladder. These are likely two stones because of the degree of echogenicity and posterior shadowing. If you have one or two objects in the gallbladder and you're not sure if they're stones, it can be useful to have the patient lay on their side. If the objects moves when the patient moves, they are stones. If not, they are likely polyps or other masses growing from the gallbladder wall.

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al. (Dr. Darmas)

This non-inflamed gallbladder contains many stones. The stones are hyperechoic with posterior shadowing. The gallbladder wall is not thickened, there is no pericholecystic fluid, and no sonographic Murphy's sign, thus cholecystitis is unlikely. 

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al. (Dr. Ken Lee)

This patient w/o cholecystitis clearly demonstrates cholelithiasis. A 2002 study showed that ER doctors can diagnose gallstones with a sensitivity of 88% and specificity 96% with POCUS. 

Gallstones can be identified by hypoechoic "shadowing" behind hyperechoic stones. If there isn't shadowing, hyperechoic structures could represent polyps or sludge. In this image the stones are resting mainly in the neck of the gallbladder.

This clearly demonstrates a stone in the gallbladder neck as a hyperechoic structure with posterior shadowing. The neck is not always clearly visualized on first glance so it is important to scan through the gallbladder in two planes to exclude stones in the neck. Other signs of acute cholecystitis include pericholecystic fluid, gallbladder wall thickening (>3mm) common bile duct dilatation, and positive sonographic Murphy's sign.

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al. (Mo)

This still image shows two clear signs of acute cholecystitis. The gallbladder wall is thickened and there is pericholecystic fluid. Of note, when measuring the gallbladder wall it's better to measure the anterior wall as the posterior wall can appear enlarged due to artifact. The cut off for wall thickening is 3mm. The anterior wall is thickened in this case but is not labeled. Other signs to look for are stones, sludge, common bile duct dilatation, and overall gallbladder enlargement. 

Of note, a positive sonographic Murphy's carries a sensitivity of 63%, specificity of 93.6% and positive predictive value of 72.5%. 

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al. (Sharon)

Emphysematous cholecystitis is the result of gas formation within the wall or lumen of the gallbladder as a result of infection by a gas forming organism. It is a surgical emergency. The air in the gallbladder appears highly echogenic with mild posterior shadowing, as air next to tissue is highly reflective.

Sukh Singh, MD

A normal common bile duct should be < 4mm plus 1mm per decade after 40 years of age. A stone can clearly be seen in the area of color flow doppler. The bile duct is obviously dilated here (although  not measured). 

When searching for the CBD, it can be useful to turn color flow doppler on to ensure you're visualizing a biliary structure and not vessels. This technique was employed here.

POCUS is highly sensitive for acute cholecystitis but as many people already know, it can be hard to find the CBD, which is reflected in the lower sensitivity and specificity for this indication in many studies. 

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al. (Dr. Dop Ahilan)

When searching for the common bile duct (CBD), color doppler can be useful to differentiate vascular structures from non-vascular structures. In this case the CBD is being measured anteriorly and does not have any pulsations on color doppler. The portal vein and artery can be seen and with the CBD, make the portal triad. 

A normal CBD should be less than 4mm plus 1mm per decade after 40 years old. It should be measured inner wall to inner wall. 

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al. (Dr. Chiang)

A normal common bile duct should be <4mm plus 1mm per decade after 40 years of age. It should be measured from inner wall to inner wall. 

You should attempt to find the portal triad: the CBD, the portal vein, and the hepatic artery. You may need color flow to find all three. Here the CBD and portal vein are labeled (no labeled hepatic artery).

To get better images, especially if you're dealing with a lot of rib shadow, it can be helpful to have your patient take a deep breath and/or roll onto their left side. 

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al.

The CBD measures at 1.89cm indicating it is grossly dilated, as a normal common bile duct should be <4mm plus 1mm per decade after 40 years of age. It should be measured from inner wall to inner wall. The color doppler is used to ensure that the dilated structure is indeed a bile duct rather than a vascular abnormality.

Sukh Singh, MD

This patient has a dilated common bile duct and obstructive pattern LFTs, highly suggestive of choledocholithiasis or other biliary obstruction. No stone is visualized on this study.

A normal common bile duct should be <4mm plus 1mm per decade after 40 years of age. Here it is 9.78 mm. 

POCUS is highly sensitive for acute cholecystitis but as many people already know, it can be hard to find the CBD, which is reflected in the lower sensitivity and specificity for this indication in many studies. 

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al. (Dr. Ken Lee)

This normal gallbladder image shows how to measure the anterior wall of the gallbladder. A normal gallbladder wall should be less than 3mm. The posterior wall should not be measured as it can appear enlarged due to artifact. 

Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al.

The image above is from a patient presenting to the emergency department with recurrent abdominal pain. The image demonstrates a large amount of biliary sludge within a normal sized gallbladder. Biliary colic from intermittent obstruction was suspected. While the gallbladder wall is noted to be mildly thick here, cholecystitis was ruled out based on other clinical factors.

Marco Garrone, MD - Torino, Italy

Echogenic material can be seen within this gallbladder but there are no stones. It is not bright white (it is not highly echogenic) and furthermore there isn't any shadowing. When there is no shadowing consider polyps or in this case biliary sludge.

Free fluid can be appreciated around this gallbladder. This is called pericholecystic fluid. However there are no stones, nor gallbladder wall thickening, and the sonographic Murphy's is negative. This free fluid is unlikely to be caused by cholecystitis. In this case, the free fluid came from a different source.

38 y/o F presented with abdominal pain, nausea & vomiting. POCUS shows the WES (Wall-Echo-Shadow) sign. This shows a curvelinear hyperechoic line representing the gallbladder wall, followed by a thin hypoechoic line representing a small amount of bile, then a curvelinear hyperechoic line, followed by acoustic shadowing. This sign is seen when the gallbladder has either a large gallstone or multiple small gallstones in a contracted gallbladder taking up the extent of the lumen. Sometimes this sign is misinterpreted as an air filled loop of adjacent bowel.

In this clip, the gallbladder (center right of the screen) appears collapsed and the wall looks thickened. This is the normal appearance of a postprandial gallbladder which is contracted because it has just released its bile content into the duodenum for digestion of a meal.

Hannah Kopinksi and Dr. Lindsay Davis - NYU Emergency Medicine

In this clip we see the liver on the left of the screen, and in the center right a large anechoic ovoid structure which is the gallbladder. The gallbladder in long axis together with the portal triad in cross-section form the “exclamation point sign”.

In this clip we see the liver on the left, and the IVC inferior to the liver with a hepatic vein draining into it. The ovoid anechoic gallbladder is in long axis in the center of the screen. To the left of the gallbladder we see the portal vein in cross-section. Running just superior to the portal vein, in long axis, is the narrow common bile duct.
