.
On the day of admission, no new infarction was found in the head MRIs, and the diagnosis and treatment was based on peripheral dizziness, and the symptoms of dizziness on the next day continued to be unrelieved, and walking was unstable, and DWI (magnetic sequence) negative cerebral infarction was not excluded
.
The treatment was adjusted to aspirin enteric-coated tablets + clopidogrel tablets for double anti-platelet aggregation, eureclin needles and burephthalide softgels to improve collateral circulation, edaraven dexanderol injection to scaveng free radicals, rosuvastatin calcium tablets lipid-lowering and stabilization spots, etc

Sum up
Lesions that cause dizziness/vertigo are cerebellar worms, knots, pompoms, the lower level of the pontine, and the lateral dorsal and bridge armsof the medulla oblongata.
Let's go back and look at the skull MRI in this case, whether it is clear at a glance, and the places marked in the following figure are the responsible lesions
we are looking for.
