case_images: Magnetic resonance images from patient depicting abnormal findings. (a) Axial T2 weighted MR image through the nasopharynx demonstrating a small well-circumscribed T2 hyperintense, CSF-like cyst nestled between the longus colli muscles deep to the nasopharyngeal mucosa consistent with an uncomplicated Tornwaldt's cyst (arrow). (b) 3D time-of-flight MRA of the intracranial circulation demonstrating narrowing and irregularities with the wall of the M1 segment of the right middle cerebral artery (arrow) indicating, but not limited to, arteritis or dissection.

case_images: A follow-up MRI without contrast demonstrated remodeling of the stroke area and a Tornwaldt's cyst was also noted (Figure 2). A 3D time-of-flight magnetic resonance angiography was then performed which showed narrowing and irregularity of the M1 segment of the right middle cerebral artery (Figure 2).
