A 15-year-old boy presented with fever for 50 days, edema and hyperemia in the right eyelid and visual deficit diagnosed as chorioretinitis. One month later, the patient developed a brief episode of left hemiparesthesia and, subsequently, sudden paresis of the left upper and lower limbs without skin lesions. Analysis of the cerebrospinal fluid (CSF) revealed pleocytosis with a predominance of lymphocytes, restricting the differential diagnosis to viral infections, syphilis, inflammatory and autoimmune diseases. The last three were deemed unlikely after extensive laboratory analysis.
Magnetic resonance imaging (MRI) revealed lesions in the right basal ganglia, internal capsule and deep white matter with restricted diffusion, compatible with acute ischemic stroke ( Figure 1 ). Time-of-flight three-dimensional magnetic resonance angiography showed a lack of flow signal in the right middle cerebral artery ( Figure 1 ), and high resolution imaging of the vessel wall (HR-VWI) revealed concentric wall thickening with contrast enhancement in the right side Segments M1 and M2, indicating vasculitis ( Figure 2 ). Subsequent CSF analysis revealed elevated levels of IgG to the varicella zoster virus, and the patient was treated with acyclovir for 14 days. After treatment, HR-VWI showed a marked reduction in wall enhancement ( Figure 2).

Ophthalmic herpes zoster is associated with vasculopathy and cerebral infarction and presents significant morbidity and mortality when left untreated. Consequently, rapid diagnosis is crucial, but it can be very challenging, especially in the absence of typical skin lesions. In this context, MRI is a useful tool for diagnosing stroke and observing infectious vasculitis1,2,3.

FIGURE 1: A and B. Axial diffusion-weighted images (DWI) showing right basal ganglia, internal capsule, and deep white matter hyperintensity (arrows), which had corresponding hypointensity on the apparent diffusion coefficient (ADC) map (not shown ). This indicates restricted diffusion, consistent with acute ischemic stroke. C. Time-of-flight three-dimensional magnetic resonance angiography (3D-TOF) showing no flow signal in the right middle cerebral artery from its origin (arrow).
FIGURE 2: A. High-resolution axial post-contrast-enhanced image of the vessel wall (HR-VWI) showing irregular concentric parietal thickening and enhancement of the M1 and M2 segments of the right middle cerebral artery, consistent with vasculitis (arrows). B. Contrast-enhanced axial HR-VWI 17 months after antiviral treatment, showing marked reduction in parietal thickening of the vessel wall, with mild parietal enhancement, possibly related to sequelae of the infection (arrow).
