Liver Histology

4.7K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Diseases of the Liver and Gallbladder

2.1K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Gross Anatomy of the Liver

2.2K
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

Liver Regeneration01:24

Liver Regeneration

4.5K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Area of Science:

  • Radiology
  • Hepatology
  • Medical Imaging

Background:

  • Benign focal liver lesions arise from hepatocytes, mesenchymal, or cholangiocellular cells.
  • Imaging features can complicate differential diagnosis with malignant liver lesions.
  • Accurate differentiation is crucial for appropriate patient management.

Purpose of the Study:

  • To describe the imaging characteristics of common benign liver lesions.
  • To highlight diagnostic clues for differentiating benign from malignant lesions.
  • To emphasize the role of advanced imaging in liver lesion interpretation.

Main Methods:

  • Review of imaging findings (ultrasound, MDCT, MRI) of benign liver lesions.
  • Focus on the use of extracellular and hepatobiliary contrast agents.
  • Emphasis on differential diagnosis strategies.

Main Results:

  • Imaging features of various benign liver lesions are detailed.
  • MDCT and MRI with contrast agents improve diagnostic accuracy.
  • Helps define hepatocellular, mesenchymal, or inflammatory nature of lesions.

Conclusions:

  • Advanced imaging modalities like MDCT and MRI are invaluable for diagnosing benign liver lesions.
  • Non-invasive characterization aids in distinguishing benign from malignant conditions.
  • Informed treatment decisions are facilitated by precise diagnosis.
