Clinical Analysis of Acute Suppurative Thyroiditis in 18 Children

OBJECTIVE: To summarize our clinical experience with the diagnosis and treatment of children with acute suppurative thyroiditis (AST). METHODS: We retrospectively reviewed the clinical data of 18 children with AST treated at our hospital between January 2009 and May 2022. RESULTS: There were 8 boys and 10 girls, aged 7.8 ± 3.8 years at admission. The main clinical manifestations were fever (88.9%), neck pain (100%), and neck mass (100%). Blood and pus cultures were performed in 9 and 15 patients, respectively. All blood cultures were negative, while positive pus cultures were noted in eight cases (six Streptococcus spp., one Staphylococcus spp., and one Streptococcus spp. and Staphylococcus spp. mixed infection). Additionally, all patients received antibiotic treatment: three received antibiotics alone, seven received antibiotics and ultrasound (US)-guided needle aspiration, seven received antibiotics as well as surgical incision and drainage, and one received antibiotics, US-guided needle aspiration in addition to surgical incision and drainage. Consequently, the average length of hospital stay in patients who received antibiotics and US-guided needle aspiration was 9.1±2.9 days compared to 14.0±2.0 days in patients in the antibiotics alone group and 13.0 ± 2.2 days in patients in the antibiotics and surgical incision and drainage group. Follow-up was conducted in 15 of the 18 patients. Three patients relapsed, and the prognosis of the other patients was good. CONCLUSION: AST has atypical clinical symptoms at the early stage. Regular monitoring of the thyroid gland using ultrasonography is strongly advised in unsure cases. Antibiotics combined with US-guided aspiration is a safe, effective, and minimally invasive treatment for AST in children and can reduce hospital stay. However, surgery may be necessary, particularly in the presence of complications. It is strongly recommended that patients with recurrence be examined for anatomical abnormalities and undergo radical treatment.
