Giant cell arteritis associated with pericarditis and pancreatic insufficiency in a patient with psoriatic arthritis.

A 63-year-old woman with psoriatic arthritis developed arthralgias and shoulder girdle myalgias which were controlled with amitriptyline. Some months later she presented with headache, jaw claudication, weight loss, and chest pain. Anemia of chronic disease, cholestasis, steatorrhea, and pericardial effusion were noted. Giant cell arteritis (GCA) was diagnosed on temporal artery biopsy and prednisone was begun. Her symptoms rapidly abated but steatorrhea continued. It is suggested that these problems were related to GCA. Physicians need to be alert to the diverse presentations of GCA.
