Abstract
A 22-year-old male presented with a gradually progressive right neck swelling, associated with right oropharyngeal lateral wall bulge. MRI showed a well-defined 10.8 cm cyst in the right parapharyngeal space indicating a type-IV branchial cyst, one of the largest documented in literature. Surgical excision was performed. Histopathology ruled out malignancy. Follow up for 18-months uneventful.
