CTICasesEsophageal Intramural Lipoma
Imaging findings
CT incidentally demonstrates a focal fat-attenuation intramural lesion in the esophageal wall on a study obtained for lung nodule follow-up, consistent with an esophageal intramural lipoma.
Key takeaways
Esophageal lipomas are rare benign submucosal tumors that appear as homogeneous fat-attenuation intraluminal or intramural lesions on CT. They are typically asymptomatic incidental findings requiring no further evaluation or treatment. The differential for esophageal intramural lesions includes leiomyoma (soft tissue density) and lipoma (fat density); CT attenuation confidently distinguishes these.
