Cavernous malformation of midbrain resulting in bilateral (right > left) increased T2 signal and slight mass effect of the inferior olivary nuclei, suggesting the diagnosis of hypertrophic olivary degeneration.
- Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
This case is subtle and may be unilateral (right only), although increased T2 signal is seen in both olives. Palatal myoclonus would help confirm the diagnosis.
