Brief SummaryAfter admission, we administered hydration and cefuroxime for urinary tract infection. On 11/20, brain magnetic resonance imaging (MRI) showed left middle cerebral artery (MCA) M1 stenosis with correlated acute ischemic stroke. The patient had some muscle power fluctuation, and we administered aspirin 200mg PO loading follow by 100mg PO QD. On 11/21, the patient had mild increased right upper limb dysmetria. We increased hydration to 60ml/hr, and the ataxia improved in the afternoon. Computed tomography angiography/angiogram (CTA) confirmed the left MCA M1 stenosis.We will keep acute stroke treatment and initiate rehabilitation plan recently.Current Problems And PlansProblem 1:Acute ischemic stroke in left middle cerebral artery territory with M1 stenosis, presented with right hemiparesis, right facial hypoethesia, last normal time in 2019/11/16 Assessment:There was no bulbar symptom, but there was definitely right hemiparesis. Patient's mentality cannot cooperate with detail sensory test.1 yr - BWL 9kg6 mo - poor oral intake, urinary incontinence11/16 Right weakness, body deviation to right11/17 Fall=>black out*1hr(?), dizzeness(aggreviated after posutral change).Mild urinary discomfort, frequency was noted, unknoen period.Brain MRI- Acute infarcts in left corona radiata, head of left caudate nucleus, and left temporal lobe.- Atherosclerosis of intracranial arteries.Suspect focal stenoses in left M1 segment MCA and left A1 segment ACA.- Old insult with encephalomalacia and hemosiderin deposition in left temporal lobe.- Suspect old infarcts in bilateral coronae radiatae and bilateral basal ganglia.- Brain atrophy, ventriculomegaly, periventricular and subcortical white matter changes.- Right mastoid and middle ear effusions.施裕翔醫師-放診專 1006CTA of head and neck without and with contrast medium images are obtainedImpression:- Atherosclerosis.Focal stenoses in left M1 segment MCA and left A1 segment ACA.Suspect mild stenoses in right M2 segment MCA(superior division), basilar artery(BA), and left V4 segment vertebral artery(VA).- Recent infarcts in left corona radiata and left basal ganglion.- Old insult with encephalomalacia in left temporal lobe.- Suspect old infarcts in bilateral coronae radiatae and bilateral basal ganglia.- Brain atrophy, ventriculomegaly, and periventricular white matter changes.- Suspect ground-glass opacity (GGO) in LUL lung(0.9cm, Srs/Img: 5/3). Suggest follow up to exclude neoplasm.- Bilateral thyroid nodules, up to 1.1cm in size
