Third Branchial Cleft Cyst with Mycobacterium Infection:

[摘要] Branchial cleft anomalies result from developmental changes of the branchial apparatus.1 Third branchial cleft anomalies are rare entities, with a prevalence of 2% to 8%.2 The most common presentation is a left-sided recurrent neck abscess or suppurative thyroiditis. Diagnosis is established by barium swallow and computed tomography. Acute infection is commonly treated with a course of antibiotics, as well as incision and drainage. Definitive treatment options include excision of the surgical sinus tract with or without hemithyroidectomy or endoscopic cauterization of the sinus tract in the pyriform sinus.3 There is limited research on the microbiology of these infections. We report a case of a third branchial cleft cyst with mycobacterial superinfection. There are no reports in the literature of a third branchial cleft cyst with mycobacterial superinfection. Unusual organisms, including Mycobacterium, may need to be considered to avoid recurrence. The study was approved by the SUNY Downstate Institutional Review Board.
