[Diagnostic problems apropos of 2 clinical cases of lumbar Pott's disease].

Two cases of POTT's disease without radiological osteoarticular destructions have been diagnosed from a psoas and a dorsal abscess. Bacteriology and histology were negative at the beginning, then became positive after a long evolution of the wound. The recommendation is to think of POTT's disease when confronted with any paravertebral abscess, with or without radiological signs and to repeat the bacteriological and histological tests if necessary.
