Carbon monoxide poisoning can produce several nonspecific symptoms and can mimic several diseases. Most of the effects are due to hypoxia. Neurologic sequelae are significant and may be delayed in onset. Hyperbaric oxygen plays an important role in the management of carbon monoxide poisoning.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is the current nomenclature for small-vessel vasculitides, including microscopic polyangiitis, granulomatosis with polyangiitis, and eosinophilic granulomatosis with polyangiitis. All affect small vessels and involve autoantibody formation against the antigens proteinase 3 and myeloperoxidase. The most commonly affected tissues are the upper and lower respiratory tract, kidneys, skin, and peripheral nerves. Acute exacerbations may be accompanied by nonspecific inflammatory symptoms, such as arthralgia, fever, and myalgia.

Neurovascular injury is a broad topic that includes injury to different neuroanatomical sites. They can occur either extracranially or intracranially and can manifest as an arterial dissection, pseudoaneurysm, fistula formation, and thrombosis or occlusion of the involved vessel. A high index of suspicion is needed to diagnose vascular injuries in an accurate and timely manner because most patients have no focal neurologic deficit on presentation.
