What is Microvesicular steatosis?
Microvesicular steatosis is characterized by small intracytoplasmic fat vacuoles (liposomes) which accumulate within hepatocytes. Common causes are tetracyclines, acute fatty liver of pregnancy, Reye’s syndrome, and hepatitis C.
What is the difference between Microvesicular and Macrovesicular steatosis?
Microvesicular steatosis is characterized by the presence of numerous small vesicles of fat that do not displace the nucleus (Figures 1, 2). Macrovesicular steatosis is characterized by engorgement of the hepatocyte by a large fat globule that displaces the nucleus.
