Leukocytosis, abnormal latex fixation test and fever are in keeping with cell arteritis is an inflammatory, the diagnosis. It is likely that many patients with GCA have Giant (GCA) occlusive ophthalmoplegia in the course of their illness and failure arteriopathy of unknown aetiology.

There is a female preponderance visual loss, but if both conditions are present, the former and it is confined almost exclusively to caucasians. It is precedes the latter in the majority of cases4. In our case, the associated with numerous neurological manifestations, involvement ofthe right medial longitudinal fasciculus with however, neuro-ophthalmological symptoms are the most the sympathetic fibres causing Horner's syndrome and commonly recognized, occurring in up to 40% ofcases in some ophthalmoplegia, represent a rare combination series1.

It is of fundamental importance to recognize together with those the reference, in unusual manifestation of GCA, which has possibly been this condition because it is remediable and the delay overlooked in the past.
