“…Mean SUVmax value of these lesions was calculated as 7.96. The differential diagnosis of multiple cavitary nodules should include lung cancer (squamous cell carcinoma, bronchioloalveolar carcinoma), Hodgkin lymphoma, metastatic disease, granulomatosis with polyangiitis, septic embolism, rheumatoid nodules, hydatid cyst, and traumatic pneumatoceles ( 14 ). Mean SUVmax values in patients with different radiologic subtypes (typical, focal and others) were statistically similar (p=0.142) ( Table 2 ).…”

Objective:Organizing pneumonia (OP) is a rare lung condition that is characterized by the presence of polypoid tissues due to fibroblastic plugs within respiratory bronchioles, alveolar ducts and sacs. The three main radiologic patterns of OP include typical, solitary-focal and infiltrative forms. The maximum standardized uptake value (SUVmax) on positron emission tomography-computed tomography (PET/CT) may be high in benign conditions such as OP as well as malignant diseases. The aim of our study was to investigate PET-CT characteristics of OP in patients mimicking lung cancer.Methods:The clinical and radiologic characteristics of 50 patients who were referred to our hospital for PET/CT evaluation due to suspicion of lung malignancy, and who were pathologically diagnosed as OP between 2009 and 2013 were retrospectively reviewed.Results:The mean age of the patients was 58.2 years. Ninety-six percent of patients (48) were male. Radiologic evaluation revealed 27 (54%) focal involvement, 10 (20%) consolidation with air-bronchogram (typical), 1 (2%) infiltrative and 12 (24%) other types of involvement (multiple nodules and cavitary lesions). The mean SUVmax value of the lesions on PET/CT was calculated as 6.5. Mediastinal lymph node involvement (at least one station) was detected in 76% of our study group with a mean SUVmax value of 3.27.Conclusion:OP may cause false positive results on PET/CT. However, PET/CT results may be used as a guide for invasive procedures that should be performed when there is suspicion of malignancy.

“…(1) Gram negative, anaerobic bacteria and occasionally streptococcus pneumonia are responsible for breakdown and abscess formation with subsequent cavitation. (3) An air bronchogram is usually associated with lobar pneumonia and suggests air in bronchi against a background of consolidation. (4) Typical appearance of community acquired pneumonia is one of a single subpleural area of alveolar consolidation with blurred margins restricted to the area next to the fissures progressing to a systemized segmental opacity affecting one or several contiguous segments or a lobe with or without the air bronchogram sign.…”

“…Mucoid impacted dilated bronchial tree is commonly seen in allergic bronchopulmonary aspergiillosis with central bronchiectasis also noted in this condition. (3,10,13) Bronchiectasis with or without mucoid impaction can also be seen in tuberculosis and other bacterial infections. (7) Traction bronchiectasis is seen in areas of scarring or fibrosis where there is traction on the walls of the bronchi by fibrous tissue.…”

“…(15) Cavitatory lesions are also seen in opportunistic fungal infections. A crescent sign suggests intracavitatory contents with a thin crescent of residual air (3,4) Crescent sign is commonly seen in fungal infections as in an aspergilloma (3) Lung abscess is often preceeded by aspiration. Aspiration commonly occurs in patients with alcoholism, immune supression, poor dental hygiene and mental retardation.…”

The purpose of this study is to describe the spectrum of findings that can be seen on CT scan in pulmonary infections. MATERIALS AND METHODS: A retrospective analysis of 100 patients with pulmonary infections who had undergone CT/HRCT scans of the chest in our Department or Radiology at Terna Sahyadri Speciality Hospital & Research Centre affiliated to Terna Medical College in Navi Mumbai was done to analyze the various findings. The CT findings were grouped and tabulated to assess the predominance of various findings on CT scan. RESULTS: Out of the 100 patients analysed, consolidation and lymph nodal involvement were the dominant findings. There were overlap of findings in some of the patients. Lymph nodal involvement was noted in all the cases with majority having mediastinal nodal involvement rather than hilar, which is not seen clearly on a plain X-ray chest. The other CT findings were nodules, pleural fluid, post infective sequalae, ground glassing, bronchiectasis and cavities. CONCLUSIONS: The role of imaging in pulmonary infection is to determine the presence of, localization of, and extent of infection, to detect predisposing factors, to detect complications and in follow up of the infection. Radiological signs on plain X-ray of chest are often not very typical and have a limited role in predicting the cause and infecting organisms. Computed tomography(CT) scan with post contrast study whenever required and high resolution computed tomography(HRCT) are the best available modalities to assess the lung parenchyma, interstitium, mediastinum and pleura.
