Eight-and-a-half syndrome, a combination of one-and-a-half syndrome and ipsilateral facial palsy, was first described by Eggenberger in 1998. Intracranial capillary telangiectasia (ICT) is a rare type of latent cerebral vascular malformation characterized by a number of small, dilated, and thin-walled blood capillaries with normal brain tissues between them. Susceptibility weighted imaging is the recommended diagnostic method to detect ICT. Oommen once reported 1 case about pontine hemorrhage causing Fisher one-and-a-half syndrome with facial paralysis. Here, we report a case with regard to pontine tegmentum ICT and hematencephalon presenting as eight-and-a-half syndrome.

Eight-and-a-half syndrome is a rare neuro-ophthalmologic condition, which is characterized by ipsilateral horizontal gaze palsy, internuclear ophthalmoplegia (INO), and ipsilateral lower motor neuron facial palsy. We report a case of eight-and-a-half syndrome secondary to acute brainstem infarction. A 55-year-old gentleman with underlying diabetes mellitus and hypertension presented with a sudden onset of double vision in the right lateral gaze for one day.

One-and-a-half syndrome occurs when the lesion involves the MLF and the ipsilateral abducens nuclei or the paramedian pontine reticular formation (PPRF) in the dorsomedial tegmentum of the pons. When the lesion is large enough, the fascicles of the facial nerve (CNVII) can also be involved, resulting in an ipsilateral facial nerve palsy.

Case report: Lateral medullary syndrome with eight-and-a-half syndromes.

Rationale: Lateral medullary syndrome is caused by atherosclerosis or embolism of the vertebral artery and its branches or the posterior inferior cerebellar artery (PICA).The eight-and-a-half syndrome is a rare pontocerebellar nerve-ocular syndrome presenting as a one-and-a-half syndrome plus ipsilateral seventh cerebral nerve palsy. The dorsolateral medullary syndrome combined with the eight-and-a-half syndromes is even rarer, so it is important to recognize the features of the classical brainstem syndrome and the eight-and-a-half syndromes.

An 88-year-old white female was admitted with a hypertensive emergency and a sudden onset of abnormal extraocular movements and facial (cranial nerve VII) palsy. This article presents a case of the eight-and-a-half syndrome and discusses its underlying clinicopathology, including a review of the neuroanatomy related to the lesion causing the eight-and-a-half syndrome in this patient.
