Polyostotic fibrous dysplasia and chronic osteomyelitis in a 12-year-old boy. Diagnostic difficulties in double bone pathology.

A twelve-year-old boy with double bone pathology (polyostotic fibrous dysplasia and chronic monofocal osteomyelitis), causing radiologic diagnostic difficulties is reported. The nuclear scan which was interpreted with disregard of the patient's history and physical examination lead to erroneous conclusions. Basic clinical signs and symptoms should always be taken into account when more sophisticated examinations are performed.
