Opsoclonus myclonus syndrome : a case report of two patients and review of the literature

Abstract EN

Opsoclonus myoclonus syndrome (OMS) is a very rare syndrome which presents with ataxia, opsoclonus and myoclonus.

We report the combined treatment of immunoglobulins and prednisolone compared to prednisolone alone in two patients.

The diagnosis was based on the clinical findings.

Work up for neuroblastoma was negative in both patients.

Prednisolone treatment in the first patient was associated with slow response, relapses and toxic side effects.

Immunoglobulins combined with prednisolone in the second patient were effective with neither relapse nor drug, side effect.

The clinical findings differential diagnosis and the management are discussed.

It appears that combined therapy with prednisolone and immunoglobulin gives better results. To the best of our knowledge this is first paper from the Middle East reporting this syndrome.
