Overview
MRI imaging may reveal lesions indicative of infection from acute retinal necrosis pathogens.
Key MRI Findings for Acute retinal necrosis
MRI imaging may reveal the following indicators of Acute retinal necrosis:[1]
- Increased T2 signal intensity in the optic pathway: optic nerves, optic chiasm, lateral geniculate bodies, optic radiations, visual cortex, midbrain structures, trigeminal nerves, and meninges.
- The increased intensity reveals lesions that may be indicative of Herpes simplex virus or Cytomegalovirus infection.
- Contrast enhanced CT T1-weighted images may reveal enhancement of optic nerve, optic chiasm, optic tracts, optic radiation, semilunar ganglion–Meckel cave, meninges, and midbrain.
