Pediatric Soft Tissue Neck X-Ray

Pediatric soft tissue neck X-ray is a common radiological examination used to evaluate various pathologies in the neck region, such as foreign body ingestion, airway obstruction, neck trauma, and infections. Recently, the Seoul Consensus was developed to provide a standardized approach for performing and interpreting pediatric soft tissue neck X-rays. This article provides an overview of the Seoul Consensus and its subtopics, including indications for the exam, radiographic technique, and interpretation.

Indications for Exam: Pediatric soft tissue neck X-ray is indicated for several clinical scenarios, including suspected foreign body ingestion, airway obstruction, neck trauma, and infections such as epiglottitis and retropharyngeal abscess. The exam is also useful for evaluating neck anatomy, detecting soft tissue masses, and assessing the cervical spine.

Radiographic Technique: The Seoul Consensus recommends a standardized radiographic technique for pediatric soft tissue neck X-ray, including the use of a high-speed film or digital imaging system, exposure at 60-70 kVp, and a focal-film distance of 100 cm. The child should be in the upright or sitting position, with the head in a neutral position and the shoulders relaxed. The X-ray beam should be centered on the thyroid cartilage, and the image should include the base of the skull to the thoracic inlet.

Interpretation: The Seoul Consensus provides a standardized approach to interpreting pediatric soft tissue neck X-rays. The radiograph should be evaluated for the presence of foreign bodies, airway obstruction, soft tissue swelling or masses, and abnormal cervical spine alignment. The soft tissues should be evaluated at specific levels, including the nasopharynx, oropharynx, hypopharynx, and cervical esophagus. The interpretation should also take into account the child’s age, clinical presentation, and other radiographic findings.

Subtopics:

  1. Foreign Body Ingestion: Pediatric patients are at a high risk of foreign body ingestion, which can result in airway obstruction or injury to the gastrointestinal tract. Radiographic findings of foreign body ingestion include a radiopaque or radiolucent object in the upper aerodigestive tract.
  2. Airway Obstruction: Pediatric soft tissue neck X-ray can help identify the level and severity of airway obstruction. Radiographic findings of airway obstruction include soft tissue swelling or narrowing, displacement of the airway, or complete obstruction.
  3. Neck Trauma: Pediatric soft tissue neck X-ray is useful for evaluating neck trauma, including cervical spine injuries and soft tissue injuries. Radiographic findings of cervical spine injuries include displacement or fracture of vertebral bodies, while soft tissue injuries may include swelling or hematoma.
  4. Infections: Pediatric soft tissue neck X-ray is indicated in cases of suspected infections, such as epiglottitis and retropharyngeal abscess. Radiographic findings of these conditions include soft tissue swelling and airway compromise.

as we described in detail above, Pediatric soft tissue neck X-ray is a valuable diagnostic tool for evaluating various pathologies in the neck area. The Seoul Consensus provides a standardized approach to performing and interpreting the exam that can improve diagnostic accuracy and clinical management. Understanding the indications, radiographic technique and interpretation of pediatric soft tissue neck x-ray can help clinicians provide optimal care to their patients.
