A 67 year-old male patient with multinodular goiter in reexamination.
Ultrasound Medic revealed a cystic lesion with air inside that was in posterior of right thyroid lobe. The lesion may be mimicking a calcified thyroid nodule in right lobe.
CT with CE confirmed the cyst captured contrast media which is in connection to esophagus on the right side. A Zenker's diverticulum was noted.
A Zenker's diverticulum is an outpouching that occurs
at the junction of the lower part of the throat and the
upper portion of the esophagus. The pouch forms
because the muscle that divides the throat from
the esophagus, the cricopharyngeal (CP) muscle,
fails to relax during swallowing.

DISCUSSION:
Zenker's diverticulum is always on left side of the anterior
neck.
In our case the lesion belongs to right side; and at first
sight, it looks like a calcified thyroid nodule. But
we could see some comet tail artifacts below
the lesion and hence, it does notexist the posterior
shadowing artifact like in case of a calcified lesion.
CONCLUSION:
We should take different diagnosis for any thyroid lesion
nearby the esophagus, especially before performing a
FNAC for a thyroid lesion.
