Learning objectives
To identify correctly ultrasound periportal cuffing and make an appropriate differential diagnosis.
Background
The periportal region is the anatomical space arranged around the portal vein and it includes branches of the hepatic artery,
bile duct,
nerves,
lymph vessels and virtual space.
(Fig 1) Periportal pathology may involve any of these structures and be diffuse or focal.
Radiological findings may be helpful in the differential diagnosis of this pathology.
Over 80% of lymph from the liver is drained by lymphatic collectors running adjacent to the portal veins and bile ducts at the hepatic hilium,
and they will drain into...
Imaging findings OR Procedure details
Toshiba Aplio Ultrasound.
Convex array probe (1.9-6 mhz)
Conclusion
Radiographic findings observed by CT,
MRI and ultrasound may be useful in the diagnosis of periportal pathology.
As already mentioned before,
the sign of ultrasound periportal cuffing is an extremely rare,
with a prevalence of approximately 0.95%,
and can be seen as high or low echogenicity,
being more frequent hyperechoic than hypoechoic periportal cuffing .
Hyperechoic periportal cuffing is common in patients with inflammatory bowel disease,
whereas hypoechogenic one often is associated with malignancies,
particularly haematologic.
In many cases the radiologic features are not specific,...
