Bilateral Lateral Hypopharyngocele (Cervical Esophageal Diverticulum)

|

I recently was asked to review this interesting (and rare) disorder in which a diverticulum or pouch has formed on both sides of a patient's upper esophagus. This condition which I'll call bilateral lateral "hypopharyngocele" is even more rare than Zenker's Diverticulum which is also not very common.

Check out the barium swallow which shows a barbell like image. The "barbell" part is the abnormal pouch and is found on both sides.

A paper was actually written about this condition by Dr. Chang.
