title: Branchial fistula arising from pyriform fossa: CT diagnosis of a case and discussion of radiological features.
abstract: Anomalies of third or fourth branchial apparatus origin are very uncommon and present as recurrent neck infections or thyroiditis with a predominant left-sided involvement. Radiological diagnosis requires a high index of suspicion and is critical for initiation of proper treatment. We describe a case of branchial sinus of pyriform fossa with external fistulization that presented in adulthood and was diagnosed on computed tomographic scan. The radiological features of this rare anomaly are revisited.
