Role of Multidetector Computed Tomography with Contrast in Evaluation of Congenital Lung Malformations in Pediatric Age Group at a Tertiary Care Hospital: An Observational Study

Abstract

Background: Computed tomography (CT) has a larger role in the noninvasive examination of congenital lung abnormalities, thanks to the introduction of multidetector CT (MDCT). If a surgical lesion is suspected, it is often necessary to use cross-sectional imaging, such as CT, for diagnosis confirmation, further lesion definition, and preoperative evaluation. Aims and Objectives: The aim of this study was to enhance comprehension of the occurrence and varieties of congenital lung abnormalities in children, as well as to assess and compare the diagnostic precision of MDCT with that of surgical intervention. Methodology: MDCT with contrast CT was performed in children with respiratory complaints and prenatal history of suspicion in targeted imaging for fetal anomalies (TIFFA) or congenital lung malformations (CLMs) using TOSHIBA 8 slice CT; the study population consisted of 40 pediatric patients with a history of chest anomalies during pregnancy in TIFFA or children with abnormal chest X-ray suspicion of lung anomalies for 18 months. Results: In a study of 40 pediatric patients who underwent MDCT with contrast to evaluate CLMs, 6 were excluded from further evaluation with contrast due to the absence of pulmonary anomalies on plain CT, leaving a possible diagnosis of s CLM in the remaining 34 cases. Of these, cystic pulmonary airway malformations (CPAM) (41.1%) were the most common, followed by congenital lobar emphysema (17.6%), bronchogenic cyst (14.7%), lung agenesis (11.6%), and phylogenetic lung. Conclusion: To notice the characteristics and related anomalies of CLMs and aid in the presurgical evaluation of CLMs, the study concludes that MDCT with contrast is the imaging of choice.
