The presence of a nasogastric tube does not alter the findings of VFSS; however, it might increase the incidence of respiratory compromise when aspiration is present.

DECT at all energy levels with metal artifact reduction software and higher energy extrapolations without metal artifact reduction software reduced metallic artifact and enhanced image interpretability compared with SECT. Radiation dose with DECT could be significantly higher than SECT.

We describe a 16-year-old male with ultrasound evidence of a 1.3 cm right paratesticular nodule, which was managed by intraoperative frozen section and excisional biopsy. The pathologic findings were consistent with benign fibrous pseudotumor of the tunica vaginalis testis, which is a very rare lesion in the pediatric population. Consideration of fibrous pseudotumor in the differential diagnosis of pediatric paratesticular masses may help prevent unnecessarily aggressive therapy.

Fluid levels appearances are not uncommon findings in different diagnostic modalities including radiography, ultrasound, computed tomography, and magnetic resonance imaging. The significance of such signs varies according to the involved sites and the clinical settings. Familiarity with their imaging features and their diagnostic value as well as their clinical implication are of paramount importance for the radiologist and the clinician. We aim to review a spectrum of examples of fluid levels encountered with different modalities in paediatric imaging and discuss their appearances and clinical significances.
