Conventional MR imaging findings
| Patient | Infarct Distribution* | Projectional White Matter Pathways Involved |
|---|---|---|
| 1 | R MCA territory involving the frontal lobe (including premotor cortex, primary motor cortex), parietal lobe (including somatosensory cortex), and temporal lobe | R corticospinal, corticobulbar, corticopontine tracts, genu and splenium of the corpus callosum |
| 2 | L and R frontal lobes (prefrontal cortex), R temporal lobe | L frontopontine tract, genu of the corpus callosum |
| 3 | L MCA territory involving the L frontal lobe (primary motor cortex, premotor and supplementary motor areas, and prefrontal cortex) and parietal lobe | L corticospinal tract, L corticobulbar and L corticopontine tracts, genu and splenium of the corpus callosum |
| 4 | Bilateral MCA territory involving bilateral frontal, parietal, and temporal lobes | L corticospinal, corticobulbar, and corticopontine tracts; genu and splenium of the corpus callosum |
| 5 | Bilateral MCA territory, most prominent in the L sensorimotor cortex and in the R parieto-occipital region | Bilateral corticospinal, corticobulbar, and corticopontine tracts |
| 6 | Bilateral subcortical white matter involving the frontal, parietal, and temporal lobes | Bilateral corticospinal, corticobulbar, and corticopontine tracts and genu and splenium of the corpus callosum |
