RESUMO
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.

Electronic cigarettes use or vaping is popular but has not been proven to be an innocuous substitute for traditional smoking. Several patterns of vaping-associated lung injuries have been reported. We report a case of a 43-year-old female patient, who presented with productive cough and an organizing pneumonia pattern on computed tomography (CT) scan. Recognizing the various CT scan patterns of vaping-associated lung injury is important to make a diagnosis because the cessation of vaping is an important step in the treatment.
RESUMO
Lymphomatous involvement of the lungs manifests in an infinite number of ways. Often there is a considerable overlap of the patterns of manifestations which comes as a diagnostic challenge to the radiologist. We retrospectively reviewed the pulmonary manifestations of biopsy proven cases of primary or secondary non-Hodgkin's lymphoma or Hodgkin's lymphoma. The patterns of lung involvement were then classified into broad categories which included large masses, mass like consolidation, nodules with or without cavitation, ground glass and lymphangitis/ perilymphatic pattern. This article illustrates the spectrum of CT manifestations of lung involvement in non-Hodgkin's lymphoma as well as Hodgkin's lymphoma.
