Polyarteritis Nodosa Causing a Vast Coronary Artery Aneurysm

Hemobilia from Ruptured Hepatic Artery Aneurysm in Polyarteritis Nodosa

Hemobilia, in patients with the diagnosis of polyarteritis nodosa, is rare at clinical presentation and has a grave prognosis. We describe a case of massive hemobilia, due to aneurysmal rupture, in a patient with polyarteritis nodosa. A 39-year-old man was admitted to the hospital with upper abdominal pain. The patient had a history of partial small bowel resection, for intestinal infarction, a...

Endovascular coil treatment of a coronary artery aneurysm related to polyarteritis nodosa

Coronary artery aneurysms (CAAs) represent a rare pathology. However, the true burden of CAAs may be currently underestimated. The use of newer imaging technologies, such as computed tomography and magnetic resonance coronary angiography, may assist in unraveling its true prevalence (1). Atherosclerosis is the main etiology of CAAs. It has been reported that 50% of CAAs are due to atheroscleros...

Polyarteritis nodosa involving renal and coronary arteries.

Abdominal pain developing from a polyarteritis nodosa-induced hepatic aneurysm.

Systemic polyarteritis nodosa (PAN) is characterized by necrotizing inflammatory changes in medium and small-sized arteries (1). Because the range of symptoms is a wide and no specific serological test exists, diagnosis of PAN could be difficult. Gastrointestinal systems such as the liver, appendix, and gallbladder are rarely affected (2). A 9-year-old female patient was admitted with severe ab...

Polyarteritis Nodosa

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...
