What is the difference between lipohyalinosis and microatheroma?

As the name suggests, a microatheroma is a small atheroma. An artheroma is what's commonly known as a plaque. It's a mass on the interior wall of arteries:

atheroma [ath″er-o´mah] an abnormal mass of fatty or lipid materialwith a fibrous covering, existing as a discrete, raised plaquewithin the intima of an artery. adj., adj atherom´atous.

Lipohyalinosis, on the other hand, is a degenerative disease marked by lipids that accumulate within the walls of blood vessels:

https://medical-dictionary.thefreedictionary.com/lipohyalinosis

lipohyalinosis (lī-pō-hī′ă-lĭn-ō″sĭs) Degenerative changes in smallblood vessels, marked by the accumulation of a glassy- orwaxy-appearing lipid within the vessel wall. This type of vasculardegeneration occurs in hypertension and atherosclerosis, andpredisposes patients to small infarcts, esp. in penetrating arteriesof the brain.

Both things are capable of narrowing arteries and reducing blood flow, which can cause a stroke. Plaques can also rupture, spilling plaque material into the bloodstream, which can then travel to a point where it lodges in a smaller artery and blocks it, which can also cause a stroke.
