Various diagnostic imaging modalities have been utilized in the assessment of pediatric neck lesions, including gray-scale and Doppler ultrasonography, conventional and three-dimensional computed tomography (CT), magnetic resonance imaging (MRI), and MR angiography, each offering distinct advantages and limitations.
Although gray-scale ultrasonography and duplex imaging are considered the first-line modalities for evaluating superficial neck masses due to their accessibility, feasibility, and cost-effectiveness, the depth of high-frequency transducers is limited, particularly in large lesions with uncertain origin or extent. Consequently, cross-sectional imaging modalities such as CT and MRI play an important complementary role by improving diagnostic accuracy and providing detailed assessment of deeper structural involvement.

Radiological characterization aims eventually to guide management by identifying the most appropriate subsequent step, which may include clinical observation, interval imaging follow-up, tissue sampling, surgical intervention, embolization, or sclerotherapy.

Pediatric patients referred to Sohag University Hospital for radiological evaluation of a neck swelling or mass. Patients will undergo clinical assessment and appropriate imaging evaluation, including gray-scale and Doppler ultrasonography as the initial imaging modality, with CT and/or MRI performed when clinically indicated. Imaging findings will be assessed for lesion detection, anatomical localization, tissue characterization, differential diagnosis, and assessment of involvement of adjacent structures.
Diagnostic accuracy of tissue characterization of pediatric neck swellings
Accuracy of multimodality imaging in characterizing pediatric neck swellings according to their imaging features and tissue composition, including cystic, solid, vascular, inflammatory, or other relevant characteristics, compared with the final diagnosis based on histopathological examination, microbiological assessment, surgical findings, or clinical and imaging follow-up, as applicable.
Time frame: From baseline imaging assessment until establishment of the final diagnosis, or up to 6 months after initial imaging, whichever comes first.
Sensitivity of multimodality imaging for diagnosis of pediatric neck swellings
Percentage of patients with a specific final diagnosis correctly identified by imaging, using the final diagnosis as the reference standard; compared with the final diagnosis based on histopathological examination, microbiological assessment, surgical findings, or clinical and imaging follow-up, as applicable.
Time frame: From baseline imaging assessment until establishment of the final diagnosis, or up to 6 months after initial imaging, whichever comes first.
Plan to share: Undecided — Individual participant data will not be shared with other researchers. Data will be analyzed and reported in aggregate form, and participant confidentiality will be maintained. Any data used for analysis will be anonymized and securely stored in accordance with institutional ethical requirements and applicable data protection regulations.
