• Intracellular accumulations
• Overview
• Intracellular accumulation of lipids
• Accumulation of Neutral fat (a triester of fatty acids and glycerol ) :Fatty change
• Accumulation of cholesterol and cholesterol esters.

• Manifestation of metabolic derangement
• Accumulation may be transient & reversible or permanent. Effects: range from harmless to toxic
FATTY CHANGE
• Steatosis
• Fatty metamorphosis
• Intracellular accumulation of neutral fat(triglycerides) within the parenchymal cells.
• Common in liver
• Can occur in heart, skeletal muscle and kidneys.
CAUSES
• ALCHOL ABUSE
• - Diabetes mellitus
• - Obesity
• - Protien Malnutrion (starvation)
• -Drugs/toxins
• -Anoxia/Hypoxia
• -Pregnancy
Other Lipid Accumulations

• Cholesterol and cholesterol esters
• In atherosclerosis, cholesterol accumulates in smooth muscle cells and macrophages in the intima of arteries
• In hereditary hyperlipemia, cholesterol accumulates in macrophages, usually under the skin, forming tumor-like structures known as xanthomas
