on with 0 comments



The correct Answer is A

  • Fatty streak
    • Earliest visible lesion – develop early in life
    • Grossly –
      • areas of yellow discoloration on inner arterial surface
      • Usually <>
      • Do NOT protrude into lumen
    • Do NOT disturb blood flow
    • Microscopically –
      • Subendothelial accumulation of foam cells filled w/ intracellular lipid (majority derived from macrophages)
      Asymptomatic and may regress over time (depends on location)
    • Often precursors to fibrous plaques
Although heart disease is not common before age 40, fatty streaks in arterial walls have been found in some 5-year-old children. Over time, these streaks can become ‘plaques’ with the potential to block arteries.
