INTRODUCTION Primary angiitis of the central nervous system is a rare disease of unclear etiology. There is no single test diagnostic of primary angiitis of the central nervous system. We report an unusual pattern on brain magnetic resonance imaging that might be specific for primary angiitis of the central nervous system. CASE PRESENTATION A 47-year-old Caucasian man developed progressive bi...

BACKGROUND "Frosted branch retinal angiitis" is an encompassing term for a rare, typically bilateral diffuse retinal periphlebitis that may occur in a number of varying conditions. To our knowledge, we report the first case of frosted branch angiitis as the presenting sign of antiphospholipid antibody syndrome in a 28-year-old woman. FINDINGS This study is a retrospective case report and lite...

PURPOSE To describe a case with frosted branch angiitis occurring in association with manifestations of Harada disease. CASE A 41-year-old man developed marked iridocyclitis, frosted branch angiitis and retinal white dots, together with serous detachment of the sensory retina in the posterior pole of both eyes. OBSERVATIONS Fluorescein angiography demonstrated multiple retinal pigment epith...

Amyloid-beta related angiitis (ABRA) of the central nervous system (CNS) is a rare disorder with overlapping features of primary angiitis of the CNS and cerebral amyloid angiopathy. We evaluated a 74-year-old man with intermittent left sided weakness and MRI findings of leptomeningeal enhancement, vasogenic edema, and subcortical white matter disease proven to have ABRA. We discuss clinicopatho...

BACKGROUND Primary angiitis of the central nervous system is an idiopathic disorder characterized by vasculitis within the dural confines. The clinical presentation shows a wide variation and the course and the duration of disease are heterogeneous. This rare but treatable disease provides a diagnostic challenge owing to the lack of pathognomonic tests and the necessity of a histological confir...

Primary angiitis of the central nervous system (PACNS) is an idiopathic disorder (vasculitis) restricted to the central nervous system (CNS). It often presents with focal neurological deficits suggesting stroke or a combination of confusion and headache. We herein report three cases with various combinations of fever, partial seizure, encephalopathy, paresis, headache and ataxia. One of them wa...

SUMMARY We report two patients with suspected primary angiitis of the CNS who underwent serial contrast-enhanced MR imaging of the spinal cord. MR abnormalities were multiple and enhancing, and located within the cervical and thoracic cord. Brain MR findings and brain biopsy specimens were positive for primary angiitis of the CNS. On follow-up MR studies, obtained after steroid and immunosuppre...

BACKGROUND AND PURPOSE There is only limited information about late neurological complications after bone marrow transplantation (BMT). The purpose of this study is to describe a cerebral angiitis-like syndrome after allogeneic BMT. METHODS Clinical and diagnostic findings of 5 BMT patients with chronic graft versus host disease and neuropathological data of 1 patient were reported. RESULTS...
