Summary
Radiological imaging revealed muscle hypertrophy, not a discrete soft tissue mass, in three children. This condition, while sometimes linked to exercise, remains unexplained in two of the cases.
Area of Science:
- Pediatric Radiology
- Musculoskeletal Imaging
- Pediatric Pathology
Background:
- Soft tissue masses in children often require radiological investigation to differentiate between neoplastic and non-neoplastic etiologies.
- Accurate diagnosis is crucial for appropriate management and to avoid unnecessary interventions.
Observation:
- Three pediatric patients presented with clinically suspected soft tissue masses in the right axilla and overlying the right scapula.
- Cross-sectional imaging, including MRI and CT, was utilized for detailed anatomical assessment.
Findings:
- Imaging demonstrated localized muscle hypertrophy rather than a distinct soft tissue mass in all three children.
- Histological examination confirmed the radiological findings of muscle hypertrophy.
- While exercise can cause muscle hypertrophy, only one child had a history of excessive gymnastic activity.
Implications:
- This case series highlights the importance of considering muscle hypertrophy as a differential diagnosis for soft tissue masses in pediatric patients.
- The etiology of localized muscle hypertrophy remains unclear in some pediatric cases, warranting further investigation.
- Radiologists and clinicians should be aware of this entity to prevent misdiagnosis and ensure appropriate patient care.
