ABSTRACT
Temporal arteritis is a form of systemic vasculitis that involves branches of the carotid artery. Clinical features are headache, visual loss, ophthalmoplegia, jaw claudication, temporal headache, with tenderness and thickening on the affected temporal artery. We present 3 cases of tongue necrosis due to this granulomatous arteritis. Ischemic necrosis of the tongue is unusual and appears to be an association between its occurrence and high dose steroid tapering.

Stroke is the main manifestation of cerebrovascular disease (CVD). Few studies report the insidious and progressive development of CVD. The aim of this study was the characterization of a CVD form without stroke in association with vascular subtypes and risk factors (VRF). From 105 CVD patients, 65 had stroke (62%), 13 of them had more than one stroke (20%), and 40 patients had a chronic progressive form (CPF) (38%). Mean evolution times up to maximum neurological deficiency were 1.57+/-0.94 and 344.25+/-210.96 days, respectively. Group results significantly associated with VRFs: hypertension (p=0.0046), hyperlipemia (p=0.0046) and atrial fibrillation (p=0.0173); with clinical manifestations: aphasia (p=0.0018), pyramidal syndrome (p=0.0000001) and small vessel disease (SVD) (p=0.0000001); and with MRI: bilateral infarctions (p=0.00009) and incomplete white matter lesions (IWMLs) (p=0.0061). Within the CPF group, dysarthria and complete infarctions were associated (p=0.00036). Most neurological disorders associated with CVD are related to CPF. The significant correlations of SVD, bilateral infarcts, IWMLs, dysarthria, several VRFs and the strong difference in evolution time up to maximum neurological deficiency values characterize CPF as a separate entity within CVD.
