- Abstract: Bilateral midbrain infarctions are often associated with basilar artery (BA) steno-occlusion, but identifying the stroke etiology is difficult when large vessels appear normal. We present a 90-year-old female with wall-eyed bilateral internuclear ophthalmoplegia. Initial diffusion-weighted imaging showed subtle bilateral midbrain lesions, while computed tomography angiography produced normal findings. Vessel-wall imaging and diagnostic angiography identified an abnormal single perforator from the distal BA supplying both sides. This case highlights the importance of these techniques in detecting perforator abnormalities in stroke with unclear etiology.
