The role of HRCT in Tropical Pulmonary Eosinophilia

Purpose: To determine the pattern of pulmonary involvement in clinically confirmed patients of tropical pulmonary eosinophilia (TPE).Method: An observational study on 13 patients with clinically confirmed TPE was performed to determine the CT scan appearances.Results: The predominant CT scan finding is the presence widespread ill-defined bronchocentric nodules, which need to be differentiated from other conditions.Conclusion: The pattern of lung involvement on a CT scan can give a clue to the diagnosis of TPE in the correct clinical context. Radiologists in tropical countries should have a high index of suspicion for this diagnosis when reading scans showing widespread ill-defined bronchocentric nodules.
