What is periportal echogenicity?
What is periportal echogenicity?
Prominent periportal echogenicity was detected during sonographic examination of patients suffering from recurrent pyogenic cholangitis, hepatocellular carcinoma and acute cholecystitis. To document the finding, 140 normal individuals were studied to establish a norm for the evaluation of the periportal echogenicity.
Why is portal vein echogenic?
The portal veins can be differentiated sono- graphically from the hepatic veins by the bright echogenic walls that surround them. This is due to the thick collagenous tissue in the portal vein walls. The hepatic veins do not exhibit echogenic borders (Fig. 1).
What is Periportal edema?
Periportal halos which may be due to blood are commonly seen in patients with liver trauma. Periportal edema may cause this sign in patients with congestive heart failure and secondary liver congesion, hepatitis, or enlarged lymph nodes and tumors in the porta hepatis which obstruct lymphatic drainage.
What is Periportal cuffing?
Aims: Hyperechoic/echo-rich periportal cuffing (ErPC) is defined as an increase in echogenicity relative to the adjacentliver parenchyma. Thickening in the periportal area may occur with proliferation of bile ducts, hemorrhage, oedema, fibrosis,inflammatory changes or a combination of these.
What does Periportal mean?
portal vein
Medical Definition of periportal : of, relating to, occurring in, or being the tissues surrounding a portal vein.
What is a Periportal?
Medical Definition of periportal : of, relating to, occurring in, or being the tissues surrounding a portal vein.
Where is the periportal region?
The periportal region is a potential space surrounding the portal vein and its intrahepatic branches. Its contents include the hepatic artery, biliary radicle, nerves and lymphatics.
What causes swollen Periportal nodes?
Background & aims: Enlarged periportal lymph nodes often are noticed during imaging of the upper abdomen. Malignant infiltration and enlargement of periportal nodes occur in patients with cancers of the liver, gallbladder, biliary tree, and pancreas and lymphoma.
What is echogenic bowel?
‘Echogenic bowel’ is the term used to describe the appearance of the baby’s bowel. It means that it appears brighter than usual. What does this mean? In most cases the cause is never found and it often disappears.
What is small bowel ischemia and what causes it?
Small bowel ischemia may be a life-threatening condition, arising from any one of numerous causes of disturbance of the normal blood flow through the small bowel wall. It can be divided into acute and chronic forms, with the main underlying etiologies (each discussed separately) being:
What does echogenic fetal bowel mean?
Echogenic fetal bowel is an observation in antenatal ultrasound imaging, in which fetal bowel appears to be brighter than it is supposed to be. It is a soft marker for trisomy 21 and has several other associations. When observed, it needs to be interpreted in the context of other associated abnormalities.
What is the prognosis of echogenic bowel disease?
Treatment and prognosis. Isolated echogenic bowel is associated with a normal outcome in 75% of cases. Workup of this finding should include, where available, an ultrasound study to assess for any associated anomalies, referral to genetic counselling, TORCH serology, cystic fibrosis carrier testing, and offer of amniocentesis.
How can I detect an echogenic bowel on ultrasound?
Antenatal ultrasound. To be truly ‘echogenic bowel’ it must be brighter than bone (e.g. femur, spine), and this should be demonstrated on an image with appropriate gain settings. Tissue harmonic imaging and compound imaging should also be switched off.
