[Low back pain as a presenting symptom in patients with infective endocarditis report of three cases and literature review].
Infective endocarditis may have different clinical manifestations that result from involvement of different organ systems. These include heart murmur, valvular bacterial vegetation, arterial emboli induced hematuria, conjunctival petechiae, subcutaneous Janeway's spots and Osler's nodes. Musculoskeletal manifestation yields arthralgia, arthritis, low back pain and myalgia, etc. Early recognition of these manifestations can lead to earlier treatment and recovery without delay. We report three cases of infective endocarditis who first presented low back pain. Their clinical features resolved with treatment. The pathogenesis of low back pain in infective endocarditis is not well-known. However, vertebral arterial embolization, vertebral septic necrosis or immune complex deposition is elucidated.
