Refers to any inflammation of the sclera including episcleritis, a benign condition affecting only the episclera, which is generally short-lived and easily treated. Classic scleritis, on the other hand, affects deeper tissue and is characterized by higher rates of visual acuity loss and even mortality, particularly in necrotizing form. Its characteristic symptom is severe and general head pain. Scleritis has also been associated with systemic collagen disease. Etiology is unknown but is thought to involve a local immune response. Treatment is difficult and includes administration of anti-inflammatory and immunosuppressive agents such as corticosteroids. Inflammation of the sclera may also be secondary to inflammation of adjacent tissues, such as the conjunctiva.

  • In addition, vascular imaging may be useful to monitor disease activity and may have prognostic value to predict future clinical events. (
  • Vascular imaging will likely play an increasingly important role in the clinical management of patients and the conduct of research in LVV and may ultimately be incorporated as outcome measures in clinical trials in these conditions. (
  • In the absence of a brain biopsy, the diagnosis is based on typical clinical and imaging abnormalities. (
  • Inclusion criteria included (1) clinical diagnosis of primary CNS vasculitis of childhood and (2) CA confirmation of suspected cPACNS. (

  • Diagnosis is based on a combination of clinical scenario, lab findings, and imaging findings. (
  • As vasculitis manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. (
  • The pathology of pulmonary vasculitis is a complex and confusing subject for several reasons: (1) in virtually all the idiopathic vasculitis syndromes, accurate diagnosis requires careful correlation with clinical and laboratory data and cannot be based on histopathologic findings alone. (

  • Overall, however, the exact mechanisms causing hypersensitivity vasculitis remain to be elucidated. (
  • Antibiotics are the most common drugs to cause hypersensitivity vasculitis, particularly beta-lactams. (
  • Malignancy accounts for 1-5% of cases of cutaneous hypersensitivity vasculitis. (
  • Effective management of malignancy can lead to resolution of the hypersensitivity vasculitis. (
  • Polyarteritis nodosa (PAN) is a form of necrotizing vasculitis primarily affecting medium-sized arteries with muscular walls, although small arteries can be affected at times. (
  • Medium sized-vessel vasculitis includes Kawasaki's Disease and Polyarteritis Nodosa . (
  • Examples of medium-vessel vasculitis are Polyarteritis Nodosa and Kawasaki disease, the latter more common in children. (
  • Medium vessel vasculitis comprises polyarteritis nodusa which affects in all age group and mostly half of diagnosed cases have been related to HBV infection. (
  • This case report evaluates data from a 29-year-old male patient with RRMS who developed fever, auricular chondritis, cutaneous vasculitis, and life-threatening diffuse alveolar hemorrhage 12 months after initiating treatment with alemtuzumab. (
  • CNS vasculitis in children is a heterogeneous group of conditions. (
  • This more benign course sets HSP apart from the heterogeneous and often progressive nature of other small and medium-vessel vasculitides. (
  • This patient had LCV of unknown cause, with no evidence of systemic vasculitis, underlying connective tissue disease, or other systemic illness. (
  • Uncontrolled systemic inflammation and aggressive atherosclerotic vascular disease may mimic vasculitis manifestations, strongly suggesting that the histopathologic confirmation of vasculitis is necessary. (
  • 1-3 Cardiac manifestations in the primary systemic vasculitides occur with variable frequency and can affect any of the cardiac layers. (
  • In this age group, lupus vasculitis would be a primary consideration and has more commonly been described with similar imaging manifestations. (
  • Studies have shown that the 5-year mortality rate is 30% to 50%, and rates of morbidity from disease complications or vasculitis treatment-related toxicity are even higher. (
  • Considering the potential serious complications of vasculitic changes, it is indispensable to obtain reliable results in the diagnostic and therapeutic process, presuming focused usage of the suitable imaging method for the specific question. (
  • It can also represent the first manifestation of a more severe disease with extra-cutaneous and potentially life-threatening complications, including systemic vasculitides, but also infections, connective tissue diseases, and malignancies. (
  • Notice that retina is attached, and no signs of vasculitis are present. (
  • Treatment for vasculitis depends on several factors, including what type of vasculitis the person has, the severity of their symptoms, their age, and their general health. (
