P194\u2005Signs in paediatric radiology; an interactive pictorial review for paediatric clinicians

Abstract

Purpose Radiology is an important facet in the management of child health. Timely recognition of diagnoses on imaging is necessary to enable initiation of appropriate therapies. In this presentation, a wide selection of radiology signs are presented. These are a mixture of common signs which should not be missed, as well as rarer signs which can easily be misinterpreted1. The signs are presented primarily on plain film, although also using other modalities including ultrasound and CT2. The signs are displayed in such a way as to allow the viewer to quiz themselves prior to the answer being revealed. This will aid in future interpretation and understanding of paediatric imaging, for both experienced clinicians and newer trainees alike. Methods Can you differentiate the steeple sign from the silhouette sign? Can you tell a deep sulcus sign from a continuous diaphragm sign? Do you know the scimitar sign from the snowman sign? Can you decide if it’s Rigler’s sign or football sign? Only after the viewer has had the opportunity to interpret the image, will the answer and explanation be revealed. For each sign, a brief overview of the radiologic features are described, along with the diagnosis and any associations. The clinical relevance of each sign is discussed1,2. Conclusion A varied selection of paediatric radiologic signs are displayed, including neonatology, chest, cardiovascular, gastrointestinal, genitourinary, musculoskeletal and neurology. The complete list of signs will not be named in this abstract, to allow the viewer to interact with the presentation, without extensive prior knowledge. After interacting with this pictorial review, the viewer will have an increased understanding of multiple signs in paediatric radiology, which will help improve management of child health.
