Centri-lobular pulmonary nodules on HRCT: incidence and approach for etiological diagnosis

Abstract Background Centri-lobular nodules are the most common pattern of diffuse pulmonary encountered on high-resolution computed tomography (HRCT). HRCT with post-processing techniques such as obtaining maximum intensity projection (MIP) is helpful in making centri-lobular more conspicuous. The study aimed to highlight role its reconstruction capabilities detection and characterization nodules, interpret frequent associated findings, correlate clinical findings reach appropriate diagnosis. Results included 58 patients; 41.4% males 58.6% females. Their age ranged from 2 67 years mean 25.69. numbers, distribution, shape, chest were identified. top three etiological diagnoses infection/inflammation 50.0% cases followed by acute viral bronchiolitis 27.6% inhalation 19.0% cases.
