Esophageal tumors: The keys to diagnosis by pneumo-computed tomography

CONCLUSION: Malignant tumor lesions (predominantly squamous cell carcinoma in the mid esophagus and adenocarcinoma in the distal esophagus) present as asymmetric wall thickening, mucosal irregularity, or mass extending into adjacent organs with lymph node involvement. Benign tumors (mainly leiomyoma being the most frequent and others such as lipoma) present as endoluminal growth, with defined borders and homogeneous attenuation. Post-contrast enhancement is scarce or moderate. The technique of computed tomography pneumotomography technique achieves an additional distension of the esophageal lumen in all cases. It allows delimiting the superior and inferior borders of the lesions, helping the surgeon to define the therapeutic strategy.PMID:38049253 | DOI:10.1016/j.rxeng.2023.03.004
