Appropriate imaging is essential in the treatment of children and adolescents with rhabdomyosarcoma. For adequate stratification and optimal individualised local treatment utilising surgery and radiotherapy, high-quality imaging is crucial. The paediatric radiologist, therefore, is an essential member of the multi-disciplinary team providing clinical care and research. This manuscript presents the European rhabdomyosarcoma imaging guideline, based on the recently developed guideline of the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) Imaging Committee. This guideline was developed in collaboration between the EpSSG Imaging Committee, the Cooperative Weichteilsarkom Studiengruppe (CWS) Imaging Group, and the Oncology Task Force of the European Society of Paediatric Radiology (ESPR). MRI is recommended, at diagnosis and follow-up, for the evaluation of the primary tumour and its relationship to surrounding tissues, including assessment of neurovascular structures and loco-regional lymphadenopathy. Chest CT along with [F-18]2-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/CT or PET/MRI are recommended for the detection and evaluation of loco-regional and distant metastatic disease. Guidance on the estimation of treatment response, optimal long-term follow-up, technical imaging settings and standardised reporting are described. This European imaging guideline outlines the recommendations for imaging in children and adolescents with rhabdomyosarcoma, with the aim to harmonise imaging and to advance patient care.

Point-of-care ultrasonography (POCUS) was initially limited to simple applications such as diagnosing ascites, sampling pleural fluid and guiding venous access. Use of POCUS is currently on the rise. As radiologists, we endorse the use of ultrasonography as the stethoscope of the future, but we make some critical comments. The interpretation of ultrasonographic findings can have far-reaching therapeutic implications. The patient is therefore entitled to maximum ultrasonographic expertise. Intensive hands-on training starting in early medical school is mandatory and central archiving of ultrasonographic images and reports is essential.

Functional constipation and functional non-retentive faecal incontinence are common problems in childhood; these functional defaecation disorders are diagnosed according to the Rome IV criteria. Here we describe the role of an abdominal X-ray in diagnosing functional defaecation disorders, and address the limited additional value of a plain abdominal X-ray. In limited cases it may be helpful to determine colonic transit time using an abdominal X-ray to differentiate between functional constipation and functional non-retentive faecal incontinence. The diagnostic value of abdominal X-rays in children with functional abdominal pain will be discussed. The aims of this article are to explore ways of reducing unnecessary use of abdominal X-rays and reducing unnecessary radiation exposure in children with functional defaecation disorders and functional abdominal pain

Caudal regression syndrome (CRS) is a rare congenital disorder characterized by developmental abnormalities of caudal spinal segments. To date, the etiology of CRS is unclear; sporadic cases are strongly associated with maternal diabetes, while familiar recurrence is infrequent. We describe in detail the prenatal clinical and sonographic findings of a recently described hereditary caudal regression syndrome, in four fetuses reported to be homozygous for a mutation in the T (brachyury) gene. The syndrome occurred in three consanguineous, but unrelated families, originating from the same geographical area. All affected fetuses had persistence of the notochord in association with abnormal vertebral ossification, sacral agenesis, and bilateral clubfoot. These findings suggest that, in case of prenatal diagnosis of sacral agenesis, an advanced ultrasound examination should assess the vertebral ossification and the rare persistence of the notochord, in order to rule the involvement of the T gene.
