| pubmed-article:19089428 | pubmed:abstractText | A 64-year-old Japanese female, diagnosed as dermatomyositis with acute interstitial pneumonia, complained of acute abdominal pain. Computed tomography of the abdomen showed hematoma in the right retroperitoneum and left rectus-sheath. Angiogram showed multiple small aneurysms on left iliolumbar artery and a horizontal linear flush, suggesting active bleeding foci in the muscles. Although arterial embolization therapy was effective for hemostatic treatment, she died of thrombotic thrombocytopenic purpura and multiple organ failure without respiratory insufficiency. Other causes of microaneurysm, such as systemic vasculitides or infectious diseases, were excluded. We considered that this is the first case report of dermatomyositis with hemorrhagic myositis associated with small aneurysms. | lld:pubmed |
