Atypical clinical case of ankylosing spondylitis

Objective. To demonstrate a clinical case of atypical ankylosing spondylitis. Materials and methods . Retrospective analysis of the medical history of a patient hospitalized in the Rheumatology Department of Gomel City Clinical Hospital No. 1. Results. Ankylosing spondylitis is one of the most difficult to diagnose causes of specific pain in the lower back. The medical and social significance of the disease lies in a high level of disability of young people, and in a decrease in the quality of patients’ life. There are no specific diagnostic markers of spondylitis at an early stage of the disease. The reasons for the late diagnosis of the disease are the untimely arrival of patients for medical help, the asymptomatic course of ankylosing spondylitis, and insufficient knowledge of the diagnostic criteria of the disease by doctors. The article presents a clinical case of atypical ankylosing spondylitis in a young patient with no signs of systemic inflammation and classic manifestations of the disease. Conclusion . Targeted examination of the lumbosacral spine and sacroiliac joints should be recommended for patients with pain in the lower back in order to verify ankylosing spondylitis.
