Metachronous pulmonary and cerebral inflammatory pseudotumor in a child
Abstract:
An 8-year-old boy had a right pneumonectomy performed for a large inflammatory pseudotumor. Over the subsequent 8 years he developed multiple similar lesions in the meninges and bilateral cerebral hemispheres as well as new growths within the ipsilateral pleural cavity and contralateral lung. Metachronous pulmonary and intracranial inflammatory pseudotumor has been reported only once. These lesions probably represent a multifocal, exaggerated inflammatory response to some as yet unidentified stimuli.
Insights
A child developed recurrent inflammatory pseudotumors in the lungs and brain after initial surgery. This rare multifocal condition suggests an exaggerated inflammatory response to unknown triggers.
Area of Science:
- Oncology
- Neurology
- Pulmonology
Background:
- Inflammatory pseudotumors (IPTs) are rare benign neoplasms of disputed etiology.
- Surgical resection is the primary treatment for localized IPTs.
Observation:
- An 8-year-old boy underwent right pneumonectomy for a large IPT.
- Over 8 years, he developed multiple IPTs in the meninges, brain, ipsilateral pleura, and contralateral lung.
Findings:
- This case represents a rare instance of metachronous pulmonary and intracranial IPT.
- The widespread, recurrent nature suggests a systemic, exaggerated inflammatory process.
Implications:
- The findings highlight the potential for multifocal recurrence of IPTs.
- Further research is needed to identify the underlying stimuli and optimize management strategies for this rare condition.
