DIFFUSE CORONARY ANEURYSMS DUE TO POLYARTERITIS NODOSA

Polyarteritis nodosa involving renal and coronary arteries.

Multiple hemorrhagic gastric ulcers due to polyarteritis nodosa.

A 73-year-old man developed refractory multiple hemorrhagic gastric ulcers. Emergent gastrectomy was performed, and the diagnosis of polyarteritis nodosa was made by histologic evaluation of the resected stomach. Although gastric ulceration is a relatively rare complication of polyarteritis nodosa, it should be considered in the differential diagnosis of refractory hemorrhagic gastric ulcers. E...

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.

Polyarteritis Nodosa

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...

Polyarteritis nodosa presenting with bilateral cavernous internal carotid artery aneurysms.

A 24-year-old man was admitted with a severe, abrupt-onset headache and diplopia. On neurologic examination, movement of the left eye was limited in all directions, while the right eye was limited on lateral gaze. Cerebral angiography demonstrated bilateral aneurysms on the cavernous portion of the internal ICA, measuring 2.4 cm on the left and 2 cm on the right (figure, A and B). Abdominal ang...
