Eight-and-a-Half Syndrome

Eyes and stroke: the visual aspects of cerebrovascular disease

“… 32 Diffusion-weighted imaging (DWI) was consistent with pontine dorsal tegmentum ischaemic stroke. 32 Felicio et al report a case of a 73-year-old man with diabetes who was found to have bilateral horizontal gaze palsy and associated right peripheral facial hemiplegia. 29 MRI revealed diffusion restriction in the midline pontine tegmentum.…”

“… 29 Eight-and-a-half syndrome is caused by lesions in the dorsal tegmentum in the caudal pons involving PPRF, MLF (one-and-a-half syndrome) and the facial nerve nucleus and fasciculus (ipsilateral facial palsy). 32 Bocos-Portillo et al describe a case of an 81-year-old man with hypertension, diabetes mellitus and dyslipidaemia who presented with left INO, horizontal left gaze palsy and left facial palsy. 32 Diffusion-weighted imaging (DWI) was consistent with pontine dorsal tegmentum ischaemic stroke.…”

Eight and a Half Syndrome from Multiple Sclerosis

“…There have been previous reports of MS causing an eight-and-a-half. In this case, the imaging highlights the anatomy behind this rare syndrome [1,4,5].…”

Clinical findings of eight-and-a-half syndrome

“…Usually facial palsy improves first followed by the ocular symptoms. The treatment depends on the underlying etiology, in addition to neurorehabilitation [ 3 , 4 ].…”
