Midbrain vasculitic aneurysms

Vasculitic neuropathy.

Vasculitis is a common and treatable cause of neuropathy. In most cases, necrotizing arteritis of the type observed in polyarteritis nodosa is responsible for the lesions, but classification of vasculitis is still uncertain. The neuropathy often occurs in the context of a multisystem disorder, but in a substantial proportion of patients, especially among patients seen by neurologists, the neuro...

Pneumococcal meningitis-associated bihemispherical acute vasculitic infarcts.

Khardenavis V, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221328 Description A 23-year-old woman with no premorbid illness presented with features of high-grade fever since 3 days.

Vasculitic neuropathy following exposure to minocycline

OBJECTIVE To report 3 patients with minocycline-induced autoimmunity resulting in peripheral nerve vasculitis. METHODS We report 3 patients who, during minocycline treatment for acne vulgaris, developed subacute onset of pain and weakness caused by vasculitis in single and multiple mononeuropathy patterns. RESULTS Each patient underwent either a nerve or muscle biopsy that confirmed vasculi...

Skin denervation in vasculitic neuropathy.

BACKGROUND Skin denervation in vasculitic neuropathy has rarely been documented despite frequent manifestations of small-fiber neuropathy including reduced sensitivity and neuropathic pain. Recently, skin biopsy has been established as a new approach to diagnose small-fiber sensory neuropathy. OBJECTIVES To investigate the pathologic features of cutaneous nerves and to evaluate inflammatory v...
