case_images: CT scan of the neck w/contrast showed a right paraesophageal air-filled diverticulum extending from the trachea (a). Grossly the specimen consisted of a 2.4 x 1.5 x 0.8 cm tan brown cystic structure with an opening of 0.2 cm in diameter (marked by arrow) and attached adipose tissue (b).

case_images: The sestamibi scan did not show any uptake, while the computed tomographic scan (CT) of the neck showed an incidental right paraesophageal air-filled diverticulum with multiple thin septations (Figure 1(a)). An opening of 0.2 cm in diameter was noted on one aspect of the lesion (Figure 1(b)).
case_images: Lesion composed of cystic spaces surrounded by inflammatory infiltrate and adjacent minor salivary gland tissue ((a): HE x100). Cystic spaces were lined by respiratory-type ciliated columnar epithelium with diffuse mild lymphocytic infiltrate ((b): HE x400).
