The diagnosis and localization of a cerebellar abscess frequently offer a perplexing problem, and any reliable assistance in its solution is always welcome. In a small series of cases we have found paralysis of conjugate lateral movement of the eyes to the side of the abscess and the frequently associated persistent conjugate deviation of the eyes away from the abscess to be a highly reliable indication of the side of the cerebellum involved. Furthermore, the presence of such paralysis in association with cerebellar disease is strongly suggestive of the presence of an abscess in differentiation from other types of cerebellar involvement, notably neoplasm. Unfortunately such paralysis is not always present in cases of cerebellar abscess, and its absence is of no differential significance.
Disturbance of conjugate movement of the eyes has not commonly attracted much attention in discussions of the symptomatology of cerebellar abscess, although its occurrence has been noted
