We present the unique case of a patient with lumbosacral radiculoplexus neuropathy (LRPN) and a small intramedullary lesion, probably an infarction, in the spinal cord. A previously healthy 58-year-old female developed acute severe pain involving the entire right lower limb, followed by weakness of the right lower limb a few hours later. The patient could not walk and was referred to our clinic. Read More

Purpose Of Review: Vasculitis of medium-sized and small vessels commonly affects peripheral nerves and can occur in context of a systemic vasculitis with multiorgan involvement or a nonsystemic vasculitis limited to the peripheral nervous system. This review summarizes the clinical and pathological features of systemic and nonsystemic vasculitis of the peripheral nervous system.

Recent Findings: Vasculitis of peripheral nerves is a diffuse process that affects the vasa nervorum along the entire length of affected nerves but appears to cause injury primarily in a zone in the proximal-middle of the nerve that is particularly susceptible to ischemic injury. Read More

Recently, guidelines have been outlined for management of immune-related adverse events occurring with immune checkpoint inhibitors in cancer, irrespective of affected organ systems. Increasingly, these complications have been recognized as including diverse neuromuscular presentations, such as demyelinating and axonal length-dependent peripheral neuropathies, vasculitic neuropathy, myasthenia gravis, and myopathy. We present 2 cases of brachial plexopathy developing on anti-programmed cell death-1 checkpoint inhibitor therapies (pembrolizumab, nivolumab). Read More

Neurofilament light chain (NFL) levels reflect axonal damage in different inflammatory and neurodegenerative central nervous system conditions, in correlation with disease severity. Our aim was to determine the possible diagnostic and prognostic value of serum and cerebrospinal fluid (CSF) NFL levels in subjects with different forms of acquired peripheral neuropathies (PN). Paired serum and CSF samples of 25 patients with acquired PN were analysed for NFL using an ultrasensitive technique (Quanterix, Simoa, Lexington, MA, USA) and compared with a group of 25 age-matched healthy subjects.

X-linked Charcot-Marie-Tooth disease (CMT 1X) is the second most common form of inherited demyelinating neuropathy. It is established that patients suffering from CMT 1X can have episodes of hemiparesis, paraparesis, quadriparesis, ataxia, aphasia, and dysarthria, which can be fully reversible, and 'trigger' factors for these episodes are usually febrile illness, high altitudes, hyperventilation, and physical activity. We describe a 22-year-old patient with a history of viral infection and sleep deprivation who presented to our department because of acute difficulty in walking and neurophysiological findings suggesting Guillain-Barre syndrome.

Nonsystemic vasculitic neuropathy (NSVN) is an under-recognized single-organ vasculitis of peripheral nerves that can only be diagnosed with a nerve biopsy. A Peripheral Nerve Society guideline group published consensus recommendations on the classification, diagnosis and treatment of NSVN in 2010, and new diagnostic criteria for vasculitic neuropathy were developed by the Brighton Collaboration in 2015.

Vasculitis is a remarkable presentation of the extrahepatic manifestations of HCV. According to the presence or absence of cryoglobulins it is subdivided into two main types: cryoglobulinemic vasculitis and non cryoglobulinemic vasculitis based on the attribution of vasculitis to serum cryoglobulins as a pathogenic factor. The attribution of cryoglobulinemia to HCV represents a success story in the history of immunology, microbiology, and clinical medicine. Read More

To clarify the roles of neutrophils in anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitic neuropathy, we studied neutrophil extracellular traps (NETs) in peripheral nerve vasculitis. Stored nerve samples from 17 patients with microscopic polyangiitis (MPA) were immunohistochemically analyzed using antibodies for citrullinated histone H3 (citH3) and various neutrophil enzymes. We defined merged citH3 and extracellularly released myeloperoxidase (MPO) as NET formation. Read More

Renaut corpuscles are cylindrical hyaline structures that arise from the peripheral nerve perineurium and project into the endoneurium. Despite their earlier accurate description in the French and German literature, Kernohan and Woltman (1938) reported very similar structures as "nerve infarcts" in a case series of vasculitic neuropathy. Krücke (1955) deserves credit for discovering this error and further explaining how peripheral nerves react differently (from brain parenchyma) to ischemia. Read More

The Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP) are the most common immune-mediated polyneuropathies, which can show variable clinical and electrophysiological manifestations. Rarer immune-mediated neuropathies encompass paraproteinemic neuropathies (PPN), multifocal motor neuropathy (MMN) and vasculitic neuropathies. The diagnosis usually relies on the history of symptom evolution, distribution of nerve dysfunction and particularly on characteristic features in nerve conduction studies, aided by cerebrospinal fluid (CSF) examination and nerve biopsy findings.

Vasculitis is a group of disorders characterized by inflammation and destruction of blood vessels, resulting in ischemic injury to the involved tissue. Sometimes, peripheral neuropathy is one of the first symptoms of systemic vasculitis. Although the classic form of peripheral nervous system vasculitis is mononeuritis multiplex, it can also present as a mononeuritis. Read More

Prompt diagnosis of vasculitis is necessary because neuropathy may be the first symptom of vasculitic syndrome, and it is crucial for the management of patients. Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, rheumatoid vasculitis, cryoglobulinemia, Sjogren's syndrome, and non-systemic vasculitic neuropathy are disorders frequently associated with vasculitic neuropathy. Pathological features such as the size of the involved vessels and the type of inflammatory cells, combined with general symptoms and laboratory data, may contribute to the specific diagnosis.
