Insights
Ultrasound effectively diagnoses early-stage acute hematogenous osteomyelitis in children by detecting subperiosteal abscesses. This imaging technique aids in differentiating osteomyelitis from other pediatric bone and soft tissue conditions.
Area of Science:
- Pediatric Radiology
- Musculoskeletal Imaging
- Infectious Disease Diagnosis
Background:
- Acute hematogenous osteomyelitis is a serious bone infection in children.
- Early diagnosis is crucial for effective treatment and preventing complications.
- Conventional diagnostic methods can sometimes be delayed or invasive.
Purpose of the Study:
- To evaluate the efficacy of ultrasound in the early diagnosis of acute hematogenous osteomyelitis in children.
- To assess the ability of ultrasound to identify subperiosteal abscesses.
- To explore ultrasound's role in differentiating osteomyelitis from other pediatric conditions.
Main Methods:
- Ultrasound examinations were performed on 24 children with suspected acute hematogenous osteomyelitis.
- Subperiosteal abscesses were identified and measured.
- Ultrasound-guided aspiration was used for fluid analysis, with surgical verification in most cases.
Main Results:
- Ultrasound detected subperiosteal abscesses in all 24 children within 4 to 14 days of symptom onset.
- Mean abscess dimensions were 86.4 mm in length and 10.7 mm in anteroposterior distance.
- Ultrasound-guided aspiration yielded purulent fluid in all cases, with 23 confirmed surgically.
Conclusions:
- Ultrasound is a valuable tool for the early sonographic diagnosis of acute hematogenous osteomyelitis in children.
- It enables prompt identification of subperiosteal abscesses, facilitating timely intervention.
- Ultrasound assists in differentiating osteomyelitis from conditions like cellulitis, soft tissue abscesses, septic arthritis, and bone tumors.
Abstract:
This article presents sonographic diagnosis of acute hematogenous osteomyelitis in early stage. 24 children with clinically suspected acute hematogenous osteomyelitis were detected to have subperiosteal abscesses by ultrasound during four to fourteen days after onset. The mean length and anteroposterior distance of the subperiosteal abscesses were 86.4 mm and 10.7 mm, respectively. Of 24 cases of subperiosteal abscesses, aspiration performed under ultrasound guidance revealed purulent fluid in all and 23 were verified surgically. The results obtained indicate that ultrasound can be used in diagnosis of acute hematogenous osteomyelitis in the early stage. The earliest case was diagnosed by ultrasound 4 days after onset. By use of ultrasound, differentiation diagnosis of acute hematogenous osteomyelitis from other diseases such as cellulitis, soft tissue abscess, acute septic arthritis and malignant bone tumors is also discussed.
