Cerebral vasculitis is a rare cause of juvenile stroke. It may occur as primary angiitis of the central nervous system (PACNS) or as CNS manifestation in the setting of systemic vasculitis. Clinical hints for vasculitis are headache, stroke, seizures, encephalopathy and signs of a systemic inflamm...
It should be noted that AE is a relatively rare cause of rhombencephalitis, as other bacterial (Listeria), viral (Herpesviridae, Epstein-Barr), and immune-mediated (Behçet) etiologies are more common [139]. Rarely, primary CNS vasculitis may resemble AE. In those cases, acquiring ...
Systemic vasculitis is a category of autoinflammatory diseases usually involving multiple organs. Involvement of the central nervous system (CNS) may mimic other disorders, hence resulting in overdiagnosis. This is a case report of a young man who presented with acrodynia, episodic pyrexia, and ...
Furthermore, a full spectrum of delayed phenotypes described includes bullous-pemphigoid like, dermal hypersensitivity reactions, lichen planus, pernio, neutrophilic dermatosis, leukocytoclastic vasculitis, granuloma annulare, and tatoo and sarcoidal reactions.37 Currently, it has been proposed that ...

ICI-induced vasculitis is rare, but potentially life-threatening. Most seen are those affective larger vessels, such as giant cell arteritis, thought to be related to PD-1 mechanisms. Paraneoplastic vasculitis should also be surveilled in patients on these unique medications [18]. ...
