Background: Persistent cervical lymphadenopathy is the typical clinical manifestation of nontuberculous mycobacterial (NTM) infection in otherwise healthy children 1-5 years of age. A positive NTM culture or PCR is necessary to proof the diagnosis. In the case of localized disease, cervical lymphadenectomy simultaneously serves both diagnosis and therapy. A typical complication of surgical treatment, i.e. incision, puncture or excision, is the formation of a fistula, which then requires further surgical intervention. In the case of an unconfirmed diagnosis, the extent of the initial surgical intervention remains unclear.
Patients and methods: On the basis of this diagnosis, 17 operations were performed in 10 children under the age of 7 years (8 female, 2 male; age 17 months to 5 years, median 36 months) in the Charité ENT clinics between 2009 and 2012. Clinical course and diagnostics, as well as the results of therapies and treatments were retrospectively analysed.
Results: Duration of anamnesis prior to initial surgery was 2-30 weeks (mean 10.4 weeks). A second intervention was performed in 7 out of 10 patients. No patient developed recurrent disease after selective cervical lymphadenectomy. The clinical course of 1 patient was complicated by a cefuroxime-responsive Staph. aureus superinfection. A second patient experienced transient accessory nerve paresis after lymphadenectomy, which resolved 2 months after the second surgery.
Conclusion: In case of persistent cervical lymphadenopathy a complete diagnostic workup is necessary. If lymphadenopathy continues to persist 1 month after a 10-day course of broad-spectrum antibiotics, a selective cervical lymphadenectomy should be performed. In order to avoid the development of fistulae and avoid secondary surgical procedures, incision, drainage and puncture should be deferred.
