Summary
Discussion
Vasculitis: Classification
Vasculitis: Classification
• Large-vessel vasculitis– Aorta and the great vessels (subclavian, carotid)– Claudication, blindness, stroke
• Medium-vessel vasculitis– Arteries with muscular wall–Mononeuritis multiplex (wrist/foot drop),
mesenteric ischemia, cutaneous ulcers• Small-vessel vasculitis– Capillaries, arterioles, venules– Palpable purpura, glomerulonephritis, pulmonary
hemorrhage
CNS AND VASCULITIS
Can it be a myopathy ?
Summary
• This case was suffering from rapidly progressive Neuromyositis (inflammatory) with negative vasculitis and connective tissue disorder profile
• Possible Differential Diagnosis1. Anti SRP positive polymyositis with
cardiomyopathy2. ANCA negative polyarteritis nodosa 3. Paraneoplastic neuromyositis
