42. Primary CNS vasculitis (PACNS)
• Defined as inflammation of the cerebral
vasculature without angiitis in other organs
affects small- and medium-sized arteries of
the brain parenchyma, spinal cord, and
leptomeninges
• 1. Granulomatous angitis of the CNS
(GACNS)
• 2. AtypicalPACNS
43. • GRANULOMATOUS ANGIITIS OF THECENTRAL NERVOUS
SYSTEM
• 20% of all patients with PACNS
• male-predominant (2:1) at any age
• mean age at diagnosis is 42 years,
• long prodromal period insidious onset of
symptoms
44. Clinical Manifestations
• Characterized by a long prodromalperiod
• Signs and symptoms of systemicvasculitis,
such as, fever, weight loss, or rash, are
usually lacking.
• highly variable and nonspecific
• PACNS should be suspected when strokes,
more often recurrent, occur in young patients
& unexplained diffuse neurologic dysfunction
45.
46. Clinical
1.Headache, the most common
symptom, (generalized / localized,
slowly worsening, spontaneously
remitting for periods, and varies in
severity)
2.Cognitiveimpairment - insidious in
onset
3.Focal neurologicalmanifestations
!!!Constitutional symptoms (fever
and weightloss) are uncommon.
Salvarani C,Brown RDJr, Calamia KT,et al. Primary central
nervoussystem vasculitis: analysis of 101patients. Ann Neurol
2007;62:442–51.
47. †P, 0.05 versus 1983–2003cohort.
‡Defined asthe presence of at least 1of the following: fatigue, anorexia, weight
loss,arthralgia.
49. Proposed criteria for PACNS
• The presence of an acquired and otherwise
unexplained neurologic deficit and with
• (a) the presence of either classic angiographic
orhistopathologic features of angiitis within the
CNS, and
• (b) no evidence of systemic vasculitis orany
condition that could elicit the angiographic or
pathologic features
50. • MR imaging =
• single or multiple, may include infarcts (both white
and gray matter) and hemorrhage, and may be
tumor-like
• Nonspecific high-intensity T2WI/FLAIR lesions in
white matter present in 42 percent of Secondary
vasculitis (low specificity )
• MR angiography — The resolution of MR
angiography (MRA) remains inadequate for the
demonstration of vasculitic changes
51. Neuroimaging
• Angiography
• positive findings if focal or diffuse areas ofarterial
stenosis, occlusion, dilatation, or beading were
detected
• findings of ectasia and stenosis referred to as"beading",
usually in the small arteries
• sensitivity of angiography in biopsy proven PACNS
cases was only 60 percent
• Thus, a negative angiogram cannot be used toexclude
the diagnosis of PACNS.
