RIGHT: Subsequent CT shows distended small bowel loops (arrowheads) that are not seen on plain abdominal film because they are filled with fluid only and do not contain intraluminal air.
Always remember :
Commonest are the commonest
Inflamed fat at sonography. Extended-view of the ventral abdomen depicting an area of hyperechoicnoncompressible inflamed fat in the omentum (red arrows). Compare this to the echogenicity of normal abdominal or subcutaneous fat (green arrows). This patient had an omental infarction.
43-year-old woman with acute calculouscholecystitis.
LEFT: US shows marked wall thickening with intramural hypoechoic nodules (arrowheads), and an intraluminal stone (arrow).
RIGHT: Contrast-enhanced CT shows a deformed and thickened gallbladder wall containing hypoattenuating nodules
LEFT: Gallbladder carcinoma. US shows marked generalized wall thickening (arrowheads), replacing the gallbladder lumen. Multiple gallbladder stones (arrow) indicate the probable location of the filled lumen.
RIGHT: Contrast-enhanced CT depicts a thick-walled gallbladder (arrowhead), with local infiltration of the mass in the adjacent liver (arrow).
Adenomyomatosis in a 39-year-old woman. US shows mural thickening with calcifications with the characteristic 'comet-tail' reverberation artifact (arrow) due to small cholesterol crystals within Rokitansky-Aschoff sinuses.
56-year-old man with liver cirrhosisLEFT: US depicts wall thickening (arrow), surrounded by ascites. Note the irregular cirrhotic liver parenchyma. RIGHT: At contrast-enhanced CT the wall of the gallbladder (arrow) appears nearly normal, because subserosaloedema can not be well differentiated from surrounding ascites at CT.
Diffuse gallbladder wall thickening in congestive right heart failure
Pancreatitis in a 56-year-old manContrast-enhanced CT shows peripancreatic inflammatory changes (arrowheads), and thickening of the wall of the gallbladder (arrow) which is secondarily involved in the pancreatic inflammation.
On follow up the peripancreatic collections increase in size and finally there are air bubbles in the heterogeneous collection, consistent with infected pancreatic necrosis.
RIGHT: two weeks later there is a rupture
