Polymyalgia Rheumatica Presenting with Fever of Unknown Origin

Abstract

ABS TRACT Fever of unknown origin (FUO) is defined as temperature higher than 38.3°C on several occasions for at least three weeks and undiagnosed after one week of study in the hospital. The most prevalent causes of FUO are infections, connective tissue diseases and malignancies. Connective tissue diseases are seen in elderly patients as temporal arteritis and polymyalgia rheumatica .Polymyalgia rheumatica (PMR) is a rheumatic disease seen after the age of 50 for which the etiology is not precisely known. Almost half of the affected patients frequently have low grade fever, malaise and poor appetite. Typical clinical characteristics are pain in both shoulders and morning stiffness. Along with this case followed up at our clinic with a complaint of fever continuing for three weeks and weakness in the arms, we will review PMR.
