Online Figure 1: Four main vascular territories of the thalamus: anterior (the polar or thalamotuberal artery from the PcomA), paramedian (the paramedian or thalamoperforate artery from P1), inferolateral (the thalamogeniculate artery from P2), and posterior (posterior choroidal arteries from P2).
Online Figure 2: Pattern 1 (43%). Bilateral paramedian thalamic (A) with midbrain (B) infarction. Sixteen of 37 cases are superimposed with increased opacity representing more commonly affected regions.
Online Figure 3: Pattern 2 (38%). Bilateral paramedian thalamic (A) without midbrain (B) infarction. Fourteen of 37 cases are superimposed, with increased opacity representing more commonly affected regions.
Online Figure 4: Pattern 3 (14%). Bilateral paramedian thalamic with anterior thalamus (A) and midbrain (B) infarction. Five of 37 cases are superimposed, with increased opacity representing more commonly affected regions.
Online Figure 5: Pattern 4 (5%). Bilateral paramedian thalamic with anterior thalamus (A) without midbrain (B) ischemia. Two of 37 cases are superimposed, with increased opacity representing more commonly affected regions.
Online Figure 6: Case 35. Axial FLAIR (A and B) and DWI (C and D) images at the level of the thalamus (A and C) and midbrain (A and C) demonstrate bilateral paramedian thalamic with anterior left thalamic and midbrain infarction (pattern 3). Notice the hyperintense signal intensity along the pial surface of the midbrain interpeduncular fossa representing the V sign (B).
Online Figure 7: Case 36. Axial DWI images demonstrate bilateral paramedian and anterior thalamic ischemia without midbrain involvement (pattern 4).
