ABSTRACT: Branchial arch anomalies can arise from the four first branchial arches,
but the most encountered cases are from the second one.
Second branchial arch cysts and abscesses occur mainly in older children or
young adults while fistulae are discovered in young children. We report a case
of complete second branchial arch fistula of Bailey III type with adult
complaints of painful swelling and local reddishness followed by spontaneous
discharge and disappearance of complaints. Diagnosis was based on ultrasound
and confirmed by CT scan, with the classic “beak sign” visible on both exams.
Three cases were encountered in the family, with no otologic or kidney
symptoms, which is quite different from the classical branchiootorenal syndrome
which associates severe inner ear and kidney congenital anomalies.
