We describe a case of infectious spondylodiscitis of the lumbar spine  complicated by epidural and bilateral psoas abscesses which started with subtle symptoms and a non-specific clinical picture. Diagnosis is based on clinical, laboratory and radiological features. It can be difficult and often delayed due to the rarity of the disease and the high frequency of low back pain in the general population. Our aim is to raise awareness for the possibility of specific low back pain which requires quick and indispensable action from the physician.
