In paediatric patients, ultrasonography is one of the preferred medical imaging modalities due to the lack of ionising radiation. Abdominal ultrasonography can be a useful tool in diagnosing cases of fungal infections but may introduce some risks for further infection in vulnerable patients or cause anxiety and discomfort. The aim of this narrative review is to analyse the utility of abdominal ultrasonography in diagnosing fungal infections in children in terms of its positive hit rates and utility in typical use. Text words and indexed terms related to ‘fungal infection and ultrasonography’ and ‘children’ were searched on MEDLINE, EMBASE, Cochrane Library and Scopus. Paediatric oncology patients, neonates and generally immunocompromised children were found to be at‐risk groups with increasing susceptibility to risk factors for contracting fungal infections. Abdominal ultrasonography was found to aid in the diagnosis of fungal infection in many cases, but not all patients with the identified risk factors were diagnosed with fungal infections and not all patients diagnosed with fungal infections had identified risk factors. Ultrasonography was found to be overutilised and the current decision process in requesting abdominal ultrasonography in diagnosing fungal infection should be revised. Further study into an effective criterion in requesting abdominal ultrasonography is suggested to reduce the overutilisation of ultrasonography, thus reducing risk of infection and discomfort while also saving time and money.
