What is Riedel’s lobe?
Riedel lobe of the liver is a simple anatomical variation, a downward tongue-like projection of the anterior edge of the right lobe of the liver to the right of the gallbladder with its typical case to be rare.
What is an accessory lobe?
An accessory lobe is an extra lobe that develops on a placenta. It is also called a succenturiate placenta. In this video, Nurse Sarah gives a quick overview of this type of placenta, her experience in having one, as well as what it means for the pregnancy.
Which Lung has accessory lobe?
right lung
The present case describes an accessory lobe between middle and lower lobes of right lung. An Azygos lobe of the lung affects the upper lobe of right lung, present in 1% individuals, where Lungs are divided into lobes by oblique and horizontal fissures.
Which lobe is bigger in liver?
The left and right lobes are the largest lobes and are separated by the falciform ligament. The right lobe is about 5 to 6 times larger than the tapered left lobe. The small caudate lobe extends from the posterior side of the right lobe and wraps around the inferior vena cava.
Is Riedel lobe normal?
Riedel’s lobe appears to be a common variant of normal anatomy, its prevalence being dependent on age-related changes in liver size and skeletal shape.
What is the difference between bipartite and accessory lobes?
A succenturiate (accessory) lobe is a second or third placental lobe that is much smaller than the largest lobe. Unlike bipartite lobes, the smaller succenturiate lobe often has areas of infarction or atrophy.
What is the accessory placenta lobe?
It is a small lobe connected to the main lobe through blood vessels. There can be second or even third accessory lobe attached with the main larger placental lobe. Accessory placenta lobe is detected during routine sonography examination during pregnancy.
What happens to the extra lobe of the placenta after delivery?
The membranes between the lobes in such placenta can be torn during delivery, and the extra lobe can be retained after rest of the placenta has been delivered, with consequent postpartum bleeding. The picture above is a so-called “accessory lobe” or succenturiate lobe of placenta.
What are the consequences of accessory lobes in the pelvis?
Such accessory lobes by themselves are of no major consequence unless large with tenuous blood supply, but they could produce problems at the time of delivery.
