We report a case of bilateral ureteral obstruction most likely caused by polyarteritis nodosa. The diagnosis was based upon muscle biopsy which showed typical necrotizing vasculitis in medium size artery in conjunction with microaneurysms in renal angiography. Ureteral obstruction is a rare manifestation of polyarteritis nodosa. This condition is thought to result from vasculitis of periuretera...

Polyarteritis nodosa (PAN) is a systemic vasculitis whose severe forms are treated with glucocorticoids and cyclophosphamide. Refractory patients are exposed to many complications, notably accelerated atherosclerosis. We report a case report of 71-year-old man followed for polyarteritis nodosa refractory to glucocorticoids and cyclosphosphamide. Systemic vasculitis relapses are followed to acce...

Polyarteritis nodosa is multisystem disease with necrotizing vasculitis of middle and small sized arteries. Takayasu arteritis is a rare nonspecific inflammatory disease with unknown cause, predominantly affecting the aorta and its main branches. In the literature, experience about the appropriate graft selection and the long-term patency is reported for vasculitis syndromes such as Takayasu’s ...

PURPOSE Polyarteritis nodosa is one of the common forms of vasculitis with multiorgan involvement. Hearing loss may be the presenting symptom of this disease. The aim of this histopathologic study was to evaluate temporal bone changes in polyarteritis nodosa and assess the correlation between otologic manifestations and histopathologic findings. MATERIALS AND METHODS A retrospective human tem...

POLYARTERITIs NODosA, as its niame implies, is ain inflammatory lesion involving the -whole three coats of the arterial system in a noclal manner. The causation of this is unknown, but its peculiar affinity for wi(despread involvement of the smaller arteries results in a multiplicity of clinical signs and symptoms, and leads to confusion and difficulty in diagnosis. The more severely affected o...

PURPOSE To demonstrate the neuroradiologic findings in patients with polyarteritis nodosa. METHODS A review of hospital records for a 10-year period revealed 50 patients with a discharge diagnosis of polyarteritis nodosa. Thirteen patients had undergone neuroimaging, and abnormal findings were found in 5 cases; these were the subjects of this study. RESULTS All 5 patients had abnormal findi...

Polyarteritis nodosa (PAN) is the systemic necrotizing vasculitis on small and median muscular vessels. Recent studies reveal that PAN consists of classical PAN and microscopic polyangitis (MPA). MPO-ANCA, which is one of anti-neutrophil cytoplasmic antibody (ANCA), is involved in the pathogenesis of MPA. In future, by the progress of research of ANCA, the definition or criteria of systemic vas...
