Patient ID: 89033147

History (HX):
Left sided palpable mass

Findings:
Large cystic mass in left posterior triangle and lateral to carotid sheath.
Rim and internal septation enhancement

Diagnose (DX):
Second branchial cleft cyst


Discussion:
The second branchial cleft accounts for 95% of branchial anomalies frequently , second branchial cleft cysts are identified alongĀ  the anterior border of the upper third of the Sternoclenoidomastoid muscle and adjacent to the muscle . However, these cysts may present any where along the course of a second brachial fistula, which proceeds from the skin of the lateral neck, between the internal and external carotid arteries, and into the palatine tonsil. Therefore, a second branchial cleft cyst is part of the differential diagnosis of a parapharyngeal mass.
