What causes Riedel’s lobe?
The etiology of Riedel lobe has been proposed to be either congenital or acquired. The congenital origin of Riedel lobe is supported by a congenital disembrioplasic anomaly in the development of a hepatic bud, which can lead to the formation of accessory lobes, in infrahepatic positions.
What does Riedel’s lobe mean?
Riedel lobe is a tongue-like, inferior projection of the right lobe of the liver beyond the level of the most inferior costal cartilage on cross-sectional images 1. It is not considered a true accessory lobe of the liver but an anatomical variant of the right lobe of the liver 3.
What is Riedel’s lobe and discuss its clinical significance?
Riedel lobe is a common anatomical variant of the liver to be aware of because it can simulate a mass. Its misidentification as a pathologic abdominal mass has led to surgery. Pathology can also occur within it (e.g. malignancy or even torsion) and cause atypical hepatic symptoms low in the pelvis 1,2.
Is Riedel’s lobe normal?
Riedel’s lobe is a normal variant form of liver which is rare. The diagnosis is usually established incidentally upon radiological examination, surgery, or autopsy. This case mostly has good prognosis, but follow up examination is still recommended for the uncomplicated case without surgical treatment.
What is caudate lobe?
The caudate lobe represents the only part of the liver that is in contact with the vena cava, except at the entrance of the main hepatic veins into the vena cava, and provides an anastomosis between the hepatic veins and vena cava.
Can you feel if your liver is swollen?
The likelihood of feeling an enlarged liver is unlikely. But because damage to your liver can cause an accumulation of fluid within your abdomen, you may notice that your stomach sticks out more than usual. You could also experience other symptoms like jaundice, loss of appetite, and stomach pain.
Can an enlarged liver be healed?
Healing can begin as early as a few days to weeks after you stop drinking, but if the damage is severe, healing can take several months. In some cases, “if the damage to the liver has been long-term, it may not be reversible,” warns Dr.
What is a lobe in the liver?
The liver has two lobes — the right and the left. Each lobe is made up of thousands of hexagonally-shaped lobules. These lobules are very small. Each lobule is made up of numerous liver cells, called hepatocytes, that line up in radiating rows. Between each row are sinusoids.
What’s the size of a normal liver?
By percussion, the mean liver size is 7 cm for women and 10.5 cm for men (Table 94.1). A liver span 2 to 3 cm larger or smaller than these values is considered abnormal. The liver weighs 1200 to 1400 g in the adult woman and 1400 to 1500 g in the adult man.
How many livers does a human body have?
But did you know that there’s one liver you don’t have to order? It’s always right inside your abdomen, up under your ribcage, and it’s very important to your health. Your liver is the largest solid organ in your body. By the time you’re grown up, it will be about the size of a football.
What is liver anatomy?
Anatomy of the liver The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm, and on top of the stomach, right kidney, and intestines. Shaped like a cone, the liver is a dark reddish-brown organ that weighs about 3 pounds.
What does hepatomegaly mean?
An enlarged liver is one that’s bigger than normal. The medical term is hepatomegaly (hep-uh-toe-MEG-uh-le). Rather than a disease, an enlarged liver is a sign of an underlying problem, such as liver disease, congestive heart failure or cancer.
What is liver enlargement symptoms?
An enlarged liver is swollen beyond its normal size. Possible causes include cancer and excessive alcohol consumption. Symptoms, when they appear, include jaundice (yellowing of the skin) and pain in the upper abdomen.
What is left lobe of liver?
Left lobe. The left lobe is smaller and more flattened than the right. It is situated in the epigastric, and left hypochondriac regions of the abdomen. Its upper surface is slightly convex and is moulded on to the diaphragm; its under surface presents the gastric impression and omental tuberosity.
