A case report of sphenoid sinusitis causing opsoclonus myoclonus syndrome
Opsoclonus myoclonus syndrome (OMS) is a rare neurological condition causing rapid jerking involuntary eye movements and myoclonus. The combination of opsoclonus and myoclonus have led to condition being coined the “dancing eyes, dancing feet syndrome”. There are a wide variety of paraneoplastic and para-infectious aetiologies for OMS and therefore a detailed workup is needed as OMS symptoms can precede the commencement of symptoms from the underlying triggering disease process. In this case report, we present a case of sphenoid sinusitis in a pregnant lady. We detail her presentation, investigatory work-up and treatment. We also review the pathophysiological theories that can lead to OMS in the current literature.
