The opsoclonus–myoclonus syndrome is a rare and distinct neurological disorder characterised by rapid multidirectional conjugate eye movements (opsoclonus), myoclonus and ataxia, along with behavioural changes in adults and irritability in children. Sometimes it is due to a self-limiting presumed para-infectious brainstem encephalitis but it may also represent a non-metastatic manifestation of neuroblastoma in children and small cell carcinoma of the lung in adults. In this article, we will describe the clinical features, diagnosis, pathogenesis and management.

An unusual case is presented of a tourist who developed fatal cerebral air embolism, pneumomediastinum and pneumopericardium while ascending from low altitude to Europe's highest railway station. Presumably the air embolism originated from rupture of the unsuspected bronchogenic cyst as a result of pressure changes during the ascent. ⋯ People with known bronchogenic cysts should be informed about the risk of cerebral air embolism and surgical removal should be considered. Cerebral air embolism is a rare cause of coma and stroke in all activities with rapid air pressure changes, including alpine tourism, as our unfortunate tourist illustrates.
