[A 4-year-old girl with a recurrent infection in the neck: a familiar picture with a rare cause]. / Een 4-jarig meisje met recidiverende halsinfecties.

ABSTRACT

BACKGROUND: Infections of the neck are frequently seen in young children and are usually harmless and transient. In the case of atypical symptoms, however, it is important to be alert to the possibility of less common causes requiring specific treatment. CASE DESCRIPTION A 4-year-old girl was seen in the outpatient clinic with a recurrent, inflamed swelling in the neck. The swelling persisted despite repeated incision and drainage. Further investigation with MRI revealed a primary branchial cleft fistula, Work type 2. The epithelialized cartilaginous fistula tract ran from the external auditory canal to the neck, very close to the facial nerve, but could be surgically removed without damage to the nerve. CONCLUSION: In a child with a recurrent swelling or abscess in the neck, with or without a fistula, an extensive differential diagnosis is required including branchial cleft fistula.
