Paraneoplastic Vasculitis in a Patient with Astrocytoma of the Brain

Abstract

Clinical case of paraneoplastic vasculitis аssociated a brain tumor was presented. Paraneoplastic vasculitis is a rare type of paraneoplastic syndrome. The frequency of detection of paraneoplastic vasculitis in cancer patients is 0.01-5%. In 70% of cases, the manifestation of vasculitis is observed long before the clinical manifestations of the tumor. Most studies report so-called leukocytoclastic vasculitis (allergic) or allergic angiitis. Vasculitis is usually accompanied by slowly progressing tumors such as breast and prostate cancer. It also develops with of stomach cancer, lung cancer, kidney adenocarcinoma, epithelioma, sarcoma, cholangiocarcinoma, other solid tumors, multiple myeloma, non-Hodgkin’s lymphoma. The nosological forms of paraneoplastic vasculitis include called polyarteritis nodosa, hemorrhagic vasculitis, Wegener’s granulomatosis, non-specific aortoarteritis, idiopathic pulmonary hypertension syndrome, thrombovasculitis, allergic hemorrhagic vasculitis, cutaneous vasculitis, systemic necrotizing vasculitis with increased ANCA titer. The patient suffered from paraneoplastic vasculitis with the development of amyloidosis of vascular tissues and arterial hypertension. The progression of the vascular process led to damage of the arteries of the brain and heart, the development of ischemic stroke and hemodynamically significant stenosis of the coronary arteries, the development of acute myocardial infarction complicated by acute heart failure, which caused death. The clinical significance of the case lies in the fact that paraneoplastic vasculitis, which was developed due to a brain astrocytoma with the formation of amyloidosis was firstly described.
