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).

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)).
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).

Histologic examination of the entire lesion confirmed the presence of cystic spaces lined by respiratory-type ciliated columnar epithelium, minor salivary gland tissue, and lymphoid aggregates (Figures 2(a) and 2(b)).
