Altered mental status
Findings
- Multifocal areas of restricted diffusion along the right greater than left ACA/MCA and MCA/PCA watershed zones
- Associated T2/FLAIR hyperintensity with mild local mass effect but no midline shift or herniation
- No acute hemorrhage
- No hydrocephalus
- Patchy subcortical and periventricular T2/FLAIR white matter hyperintensities
- Bilateral mastoid effusions
- Right pseudophakia
Diagnosis
Watershed infarcts
Sample Report
Acute multifocal infarcts along the right greater than left ACA/MCA and MCA/PCA watershed zones. Mild local mass effect without midline shift or herniation. No acute hemorrhage or hydrocephalus.
Background of chronic small vessel disease.
Bilateral mastoid effusions.
Discussion
- When you see cerebral infarcts, try to offer a preferred mechanism, as this will help the clinical team determine the next best steps. Here are some broad categories:
- Thrombotic: within a single arterial territory
- Embolic: within multiple arterial territories
- Watershed: concentrated on the borders between arterial territories
- Venous: within a venous territory
- Approximate representations of the cerebral arterial and venous vascular territories are shown in the annotated images below
