In 1891 Georg Avellis described a so-called "laryngeal hemiplegia" that can be caused by peripheral lesions of the vagal and glossopharyngeal nerves and rarely by infarctions of the medulla oblongata, thus representing a classical brainstem syndrome. In this study we describe two patients with an Avellis' syndrome caused by brainstem ischemia. Contemporary publications about Avellis' syndrome in brainstem lesions seem to be very inhomogenous. They report various diseases with unilateral laryngeal palsy due to nucleus ambiguus lesions with diverse additional neurological symptoms. We conclude that according to Avellis' original description only the combination of ipsilateral palatolaryngeal paresis and contralateral hemiparesis and/or hemihypesthesia should to be interpreted as Avellis' syndrome.

The Gasperini syndrome is a very rare brainstem disease characterized by the typical combination of ipsilateral lesions of the cranial nerves V-VII and dissociated contralateral hemihypesthesia, whereas both contralateral and ipsilateral hypacusis was described. Since the first description in 1912, only a few cases of this crossed brainstem syndrome were published so far. Pontine infarction and bleedings were the reported causes of the syndrome. Here we report a 44-year-old man with the classical Gasperini syndrome due to pontine demyelination in multiple sclerosis. The clinical findings were correlated with changes on MRI. The present case shows that classical crossed brainstem syndromes are topological terms not invariably associated with brainstem ischemia in particular vascular areas and may contribute to the differential diagnosis of peripheral facial nerve palsy.
