- Fig 1.
Infective lesion involving the upper pole of left thyroid lobe (arrow) associated with a third/fourth brachial remnant. Contrast-enhanced coronal CT reformation of the neck (A), contrast-enhanced coronal axial CT scan at the level of the thyroid gland (B), and a sonogram of the left thyroid lobe (C) show the phlegmonous lesion. Pharyngoscopy (not shown) revealed an opening at the apex of the left piriform sinus.

Extensive left-sided neck infection with abscess (thin black arrow) formation and involvement of the left thyroid lobe (thick arrow). Contrast-enhanced coronal T1 fat-saturated MR image of the neck (A), contrast-enhanced axial T1 fat-saturated MR image (B), and contrast-enhanced axial CT scan at the level of the thyroid gland (C) demonstrate the lesion well.
- Fig 3.
A, Contrast-enhanced axial CT scan at the level of the thyroid gland shows a small air pocket within the left lobe of the thyroid gland (black arrow), which is thought to be characteristic of a branchial sinus remnant. B, Pharyngoscopy photograph shows the opening (white arrow) of the branchial pouch sinus in the apex of the pyriform fossa.
- Fig 4.
Noninfected third branchial cleft cyst on the right side of the neck following the course of the embryonal thymopharyngeal duct (arrows). A, Coronal T2 fat-saturated image. B, Schematic representation of the course of the thymopharyngeal duct.
