title: Branchial fistula: CT manifestations.
abstract: A patient with a recurrent left neck abscess was found to have a branchial fistula from the pyriform sinus. This uncommon anomaly was demonstrated by CT and barium swallow. The embryology, pathology and clinical features of this lesion are discussed and contrasted with those of the branchial cyst.
