Which condition is characterized by necrosis of the liver parenchyma but may have transient elevation of liver enzymes?

The condition characterized by necrosis of the liver parenchyma with transient elevation of liver enzymes is acute hepatitis. In acute hepatitis, there is inflammation of the liver tissue, which leads to liver cell damage and necrosis. This damage allows enzymes such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) to leak into the bloodstream, resulting in elevated liver enzyme levels.

In acute hepatitis, the elevation of these liver enzymes may be significant initially but can be transient, often normalizing as the condition progresses towards recovery. This transient nature of enzyme elevation can be a distinguishing feature of acute hepatitis, indicating that while there is significant liver damage, the liver has the potential for recovery.

Other conditions listed, like cirrhosis, are associated with chronic liver injury and do not typically present with transient elevations of liver enzymes; rather, liver enzymes may remain persistently elevated. Fatty liver disease often leads to a different pattern of enzyme elevation and is typically associated with metabolic conditions. Glycogen storage diseases manifest with specific metabolic disturbances and may cause liver enlargement without the classic pattern of enzyme elevation seen in acute hepatitis. Thus, acute hepatitis is the most accurate answer as it directly relates to necrosis of liver par
