Bronchiolitis obliterans in children with Stevens-Johnson syndrome: follow-up with high resolution CT
1Department of Diagnostic Radiology, Severance Hospital, 134 Seodaemoon-gu, Shinchon-dong, Seoul 120-752, Korea.
Insights
Stevens-Johnson syndrome can cause lung issues in children, sometimes leading to bronchiolitis obliterans. High-resolution CT scans effectively diagnosed and monitored this condition in two pediatric cases without biopsies.
Area of Science:
- Pediatric Pulmonology
- Radiology
- Critical Care Medicine
Background:
- Stevens-Johnson syndrome (SJS) is a severe hypersensitivity reaction with potential for significant systemic complications.
- Pulmonary involvement occurs in approximately one-third of pediatric SJS cases.
- Airway epithelial injury is a known pathway to developing bronchiolitis obliterans (BO) in SJS patients.
Observation:
- This study presents two pediatric cases of SJS-associated BO.
- Diagnosis and monitoring were achieved using high-resolution computed tomography (HRCT).
- Open lung biopsy was not required for diagnosis in these cases.
Findings:
- HRCT demonstrated characteristic features of BO in pediatric SJS patients.
- Serial HRCT scans allowed for the observation of disease progression and changes.
- The findings highlight the utility of HRCT in diagnosing and managing SJS-associated BO.
Implications:
- High-resolution CT is a valuable, non-invasive tool for diagnosing and following bronchiolitis obliterans in children with Stevens-Johnson syndrome.
- Early diagnosis and monitoring via HRCT may improve patient outcomes.
- Further research into the long-term pulmonary sequelae of SJS in children is warranted.
Abstract:
About one third of children with Stevens-Johnson syndrome have pulmonary involvement. As a consequence of airway epithelial injury, bronchiolitis obliterans can occur in these patients. Two cases of Stevens-Johnson syndrome-associated bronchiolitis obliterans in children were diagnosed and followed by high resolution CT without open lung biopsy. Serial changes of high resolution CT features of bronchiolitis obliterans are discussed and the literature is reviewed.
