What is a Sonolucent gallbladder?
Normal Ultrasound Anatomy The gallbladder is an elliptical sac that lies inferior and medial to the right lobe of the liver. Although different layers of its wall have different echogenic properties, the gallbladder overall consists of a fluid-filled sonolucent lumen surrounded by an echogenic wall.

What size should a normal gallbladder be?
The normal adult gallbladder measures from 7-10 cm in length and 3-4 cm in transverse diameter 6. The gallbladder communicates with the rest of the biliary system by way of the cystic duct, with bidirectional drainage of bile to and from the common hepatic duct.
What does Sonolucent mean in ultrasound?
Medical Definition of sonolucent : allowing passage of ultrasonic waves without production of echoes that are due to reflection of some of the waves a sonolucent mass.
What causes gallbladder Halo?
The cause of gallbladder wall edema is the result of massive histamine release causing hepatic venous sphincter constriction and massive generalized hepatic venous congestion. Simply put, when the liver swells, so does the gallbladder wall.

What is Isoechoic?
Isoechoic – Tissue or structures which produces an echo of the same strength as that of the surrounding structures or tissues, making it difficult to isolate.
Is thickening of the gallbladder wall serious?
Gallbladder wall thickening, associated with features like perforation, fistula formation and invasion of adjacent organs, is often assumed to be malignant.
What conditions cause gallbladder wall thickening?
The thickness of the gallbladder wall depends on the degree of gallbladder distention; pseudothickening can occur in the postprandial state due to physiologic contraction.
- Cholecystitis.
- Liver Disease.
- Systemic Diseases.
- Extracholecystic Inflammation.
- Malignancy.
- Adenomyomatosis.
- Pseudothickening.
- Atypical Infection.

What does echogenic mean in ultrasound?
Echogenicity. Echogenicity of the tissue refers to the ability to reflect or transmit US waves in the context of surrounding tissues. [7–9] Whenever there is an interface of structures with different echogenicities, a visible difference in contrast will be apparent on the screen.
Is there a sonolucent zone around the gallbladder?
The implications of the finding of a sonolucent zone around the gallbladder, characterized on ultrasonography by loss of definition of the outer (serosal) aspect of the gallbladder wall with a moderately well defined inner (mucosal) surface in patients with signs and symptoms of acute cholecystitis, are described.
What does a sonolucent halo on the gallbladder indicate?
Thus this finding of a sonolucent halo about the gallbladder was important in our series, being frequently an indicator of acute cholecystitis complicated by gangrene with or without perforation of the gallbladder. Publication types Case Reports MeSH terms Acute Disease
What causes mural thickening of the gallbladder wall?
Mural thickening is secondary to edema and appears as a sonolucent line between two echogenic lines in the gallbladder wall. Although nonspecific, gallbladder distention (width > 4 cm) is a key feature because lack of any distention makes acute cholecystitis unlikely and should prompt a thorough search for another cause for this appearance.
What does a distended gallbladder look like on an ultrasound?
The ultrasound findings include lucency of the wall and a distended gallbladder containing sludge, although pericholecystic fluid or inflammation is usually absent. Fibrotic changes involving the gallbladder wall may result in a contracted gallbladder.
