Hypertrophic olivary degeneration

Case contributed by Assoc Prof Frank Gaillard

Cavernous malformation of midbrain  resulting in bilateral (right more than left) increase T2 signal and slight mass effect of the inferior olivary nuclei, suggesting  the diagnosis of hypertrophic olivary degeneration.

Case Discussion

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.
