[Circumscribed non-tuberculous osteomyelitis in children. Apropos of 31 cases]
Insights
Non-tuberculous osteomyelitis in children presents differently now, with circumscribed lesions appearing more frequently than acute osteomyelitis. Diagnosis requires clinical, biologic, and radiologic evaluation, often including biopsy.
Area of Science:
- Pediatric Infectious Diseases
- Pediatric Orthopedics
- Radiology
Background:
- Osteomyelitis presentation in children may be evolving.
- Circumscribed non-tuberculous osteomyelitis is increasingly observed.
Purpose of the Study:
- To analyze the changing presentation of osteomyelitis in children.
- To define radiologic and clinical features of circumscribed non-tuberculous osteomyelitis.
Main Methods:
- Retrospective review of 31 cases of circumscribed non-tuberculous osteomyelitis (1975-1983).
- Analysis of lesion locations (pelvis, calcaneum, long bones) and affected bone segments (metaphysis, diaphysis, epiphysis).
- Correlation of clinical, biologic, and radiologic findings with diagnostic outcomes.
Main Results:
- 31 cases of circumscribed non-tuberculous osteomyelitis treated, compared to 21 acute osteomyelitis cases.
- Lesions predominantly in long bones (20/31), followed by pelvis (8/31) and calcaneum (3/31).
- Subacute clinical presentation with inconstant infection signs; biopsy needed in 12/31 cases.
Conclusions:
- A shift in osteomyelitis presentation towards circumscribed non-tuberculous forms is suggested.
- Accurate diagnosis relies on integrated clinical, biologic, and radiologic data.
- Biopsy is crucial for definitive diagnosis in ambiguous cases.
Abstract:
Over the last eight years (1975-1983) a total of 31 cases of circumscribed non-tuberculous osteomyelitis in children have been treated as against 21 cases of classical acute osteomyelitis, suggesting transformation of the mode of presentation of this disease. Lesions were located in the pelvis (8 cases), the calcaneum (3 cases) and the long bones (20 cases), the metaphysis being affected in the latter in 13 patients, the diaphysis in 4 and the epiphysis in three. Specific radiologic images for each location are defined. Clinical expression was subacute and signs of infection inconstant. Differential diagnosis is discussed in relation to each region involved, a positive diagnosis depending on clinical, biologic and radiologic findings, with the need for biopsy in case of doubt. The latter was necessary in 12 of the 31 children. Diagnosis was confirmed in all cases by the favorable outcome from treatment.
