Although cerebral angiography should be approached with caution in the diagnosis of inflammatory cerebro-vascular disease there are some characteristic angiographic findings which may be helpful for classification and differential diagnosis. The proximal cerebral arteries are favourably affected by basal meningitis and thrombangiitis obliterans with resulting stenoses and occlusions. Whereas those inflammations originating from neighbouring skull structures mostly involve the intracavernous parts of the carotid artery, the tuberculous and mycotic arteritis prefer the supraclinoid carotid siphon. Peripheral vascular changes are found in luetic endangiitis, necrotizing and toxic angiitis and in collagenoses. Simultaneous involvement of the temporal arteries is of great diagnostic importance demonstrating the systemic character of the inflammatory process; in Horton's arteritis it can be a pathognomonic finding. Infectious endocarditis, some mycoses and malaria may lead to embolic occlusion of cerebral vessels. Mycotic aneurysms mostly have a broad base or a fusiform shape and do not prefer the localizations of congenital aneurysms. Angiographically, abscesses, tuberculomas and viral encephalitis may result in circumscribed hypervascularized areas. The characteristic angiographic findings are exemplified and discussed on the basis of 8 cases of inflammatory cerebro-vascular disease (tuberculosis, pneumococcal and unspecific bacterial meningitis, syphilis, mycosis, Takayasu-syndrome, panarteritis nodosa, temporal arteritis).

The objective of this study was to review magnetic resonance imaging (MRI) findings in patients with vascular involvement of the central nervous system (CNS) associated with systemic diseases. We reviewed the MRI findings in clinically suspected cases of vascular involvement of the CNS associated with systemic diseases. Vascular CNS involvement was considered in the presence of characteristic clinical, MRI and/or MR angiography findings. In order to be included in the study, patients needed to have a complete clinical and laboratory investigation and a follow-up of a minimum of 6 months. Twenty-four patients (17 women and 7 men), with mean age of 29.5 years had diagnosis of CNS vasculitis and were included. The clinical presentation was variable, but the most common complaints were headache in 18, focal deficits in 9, disturbances of consciousness in 9, and seizures in 8 patients. Underlying causes for CNS vasculitis were identified in all patients and included systemic lupus erythematosus in eight, tuberculosis in three, bacterial meningitis in three, Takayasu arteritis in two, polyarteritis nodosa in two, syphilis in two, drug abuse in two, yellow fever in one and varicella in one patient. Nonspecific high intensity T2WI/FLAIR lesions in white matter were the most common finding, present in ten patients. Eight patients had infarctions in large cerebral arteries territory, associated or not with high intensity T2WI/FLAIR small foci. Vascular involvement of the CNS can be found in a great variety of systemic diseases, including rheumatologic, infectious and drug abuse. Clinical findings are unspecific and MRI/MRA may help to establish the correct diagnosis.
