Multisystem inflammatory syndrome in children associated with COVID-19 presenting as cervical inflammation.

ABSTRACT

AIM: The major clinical manifestations multisystem inflammatory syndrome in children (MIS-C) are fever, gastrointestinal and cardiac. The aim of this study was to describe MIS-C in a series of patients who presented primarily with cervical manifestations. METHODS: We retrospectively reviewed medical records of all patients who met the Centers for Disease Control and Prevention and World Health Organization MIS-C diagnostic criteria treated at Hadassah-Hebrew University Medical Center between April 2020 and September 2021. RESULTS: Of 37 children diagnosed with MIS-C (median age 10.2 years, range 1.5-18 years, 20 male) five, 13.5% (median age 14.4 years, range 9.2-17.5 years) presented with cervical symptoms mimicking neck infections. One was hospitalised with a working diagnosis of retropharyngeal abscess, and four with acute cervical lymphadenitis that did not respond to early antibiotic treatment. All developed full MIS-C phenotype. CONCLUSION: MIS-C may present as cervical inflammation. An ill-appearing child with symptoms and/or signs of cervical inflammation should be evaluated for clinical and laboratory features of MIS-C, thereby facilitating prompt treatment of this potentially fatal disorder.
