Findings:
There is a tiny (7 x 4 mm) ovoid lesion in the left retropharyngeal space, located posterior to the lamina of the left thyroid cartilage at C6/7 level, which shows avid enhancement in the arterial phase and washes out on the delayed phase. A feeding artery is seen leading to this lesion.
The thyroid gland is unremarkable without evidence of enlargement or nodularity.
The tongue and the floor of the mouth have a normal appearance. The retromolar trigone is unremarkable.
Clusters of calcifications within the palatine tonsils bilaterally, compatible with tonsilloliths. The tonsils and adenoids are otherwise normal.
The pharyngeal and glottic regions are normal. The parotid and submandibular glands are normal.
Normal appearance of the aortic arch and the cervical vessels.
The imaged brain and intracranial circulation are unremarkable. The paranasal sinuses and mastoid air cells are clear. Bilateral IOL-implants are noted.
The lung apices are clear.
No bony abnormality is seen. The craniocervical junction and spinal canal appear patent.
Conclusion:
Tiny lesion (7 x 4 mm) in the left para pharyngeal space at C6/7 level, most likely in keeping with a small parathyroid adenoma.
