Radiographic manifestations of bone marrow transplantation in children
Insights
Complications after pediatric bone marrow transplant are often due to infection, toxicity, and graft-versus-host disease. Pulmonary issues and visceral organ complications are common, with osteoporosis being a key bone complication.
Area of Science:
- Pediatric Hematology/Oncology
- Transplant Immunology
- Radiology
Background:
- Bone marrow transplantation (BMT) is a critical treatment for various pediatric diseases.
- BMT recipients, especially children, are susceptible to diverse complications.
- Radiographic evaluation is essential for detecting these post-transplant sequelae.
Purpose of the Study:
- To review radiographically detectable complications in children following bone marrow transplant.
- To identify the primary causes and types of these complications.
- To correlate specific complications with underlying BMT-related factors.
Main Methods:
- Retrospective review of radiographic findings in 35 pediatric BMT patients.
- Analysis of complication types, timing, and potential etiologies.
- Correlation of radiographic findings with clinical data, including infection, toxicity, and graft-versus-host disease.
Main Results:
- Infections, chemoradiotherapeutic toxicity, and graft-versus-host disease (GVHD) were the most frequent causes.
- Pulmonary complications, primarily interstitial lung disease, were common within 2 months post-BMT and correlated with GVHD.
- Extrapulmonary visceral complications included hepatosplenomegaly, nephromegaly, and hemorrhagic cystitis.
- Less frequent complications included sinusitis, cerebral atrophy, and intracerebral hematomas.
- Steroid-induced osteoporosis was the most significant osseous complication.
Conclusions:
- Radiographic assessment is vital for diagnosing diverse complications post-pediatric BMT.
- Infection, toxicity, and GVHD are major drivers of these complications.
- Early recognition of interstitial lung disease and other visceral/osseous issues is crucial for management.
Abstract:
Radiographically detectable complications in 35 children after bone marrow transplant are reviewed. These complications are most frequently due to infection, chemoradiotherapeutic toxicity, and graft versus host disease (a transplant rejection phenomenon peculiar to bone marrow transplant patients). The pulmonary complications within the first 2 months are secondary to a form of interstitial lung disease. Interstitial lung disease has a strong correlation with graft versus host disease. Extrapulmonary visceral complications include hepatosplenomegaly, nephromegaly, and hemorrhagic cystitis. These are due to graft versus host disease, radiation, and chemotherapeutic toxicities, respectively. Sinusitis, cerebral atrophy, and intracerebral hematomas are less frequent complications. Osteoporosis due to steroids is the single most important osseous complication.
