“…Gasperini syndrome (GS) is a rare alternating brainstem syndrome resulting from a lesion in the caudal pontine tegmentum. After its first description in 1912 [ 1 ], there have only been 18 reported cases [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. While this syndrome is characterized by ipsilateral peripheral facial palsy, abducens nerve palsy, hypacusis, facial sensory loss, and contralateral hemisensory loss [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ], its definition is still ambiguous.…”
