Both during and after cancer treatment, pyogenic spondylitis is an uncommon but serious complication. Because pyogenic spondylitis is often recognized as a complication of a distant process causing bacteremia, it initially may be misdiagnosed the primary infection such as urinary tract infection. Consequently, a considerable delay in diagnosis frequently occurs. ... Read more >>
