Traumatic laryngotracheal transection is an uncommon occurrence most often secondary to blunt trauma to the neck. The most commonly described mechanism is a “clothesline” injury or strangulation, involving high speed impact of the neck across a chain, rope, chord, or strap, usually associated with the use of a motor or recreational vehicle. It is often instantaneously fatal, and those who survive may have severe respiratory compromise requiring immediate advanced airway placement, or astonishingly, they may be asymptomatic. Tracheal transection may be identified when laryngoscopic intubation fails, during the placement of a surgical airway, or during initial CT or bronchoscopic evaluation.
We describe an 8-year-old male who experienced blunt neck trauma and was intubated successfully in the pre-hospital setting. Initial radiographic evaluation was significant for severe subcutaneous emphysema and pneumomediastinum. Bilateral thoracostomy tubes were placed. Initial CT evaluation again showed extensive pneumomediastinum without pneumothorax. Four days after initial hospitalization the patient was extubated without difficulty. Post-extubation chest x-ray showed irregular tracheal borders with focal hyperlucency adjacent the mid-cervical trachea in the former position of the endotracheal tube cuff. Repeat CT of the chest showed complete tracheal transection of the mid-cervical trachea. The patient subsequently underwent surgical repair and was discharged without complication. This is the first reported case of traumatic tracheal transection not identified on initial CT examination secondary to the position of the endotracheal balloon, with subsequent discovery of the complete transection on the post-extubation radiograph.
There is 1 reported case of tracheal transection identified on initial CT evaluation in the presence of a well-positioned endotracheal tube. Additionally, there is 1 reported case of tracheal transection not identified on initial CT evaluation, however the patient was not intubated and had minimal symptoms. Tracheal transection was confirmed via bronchoscopy in that case.
Tracheal transection is rare traumatic injury that can be difficult to identify. High clinical suspicion and careful examination with multiple modalities is often necessary to make a definitive diagnosis. Read More

Children often present to the emergency room (ER) with painful neck swelling, sore throat, and difficulty breathing. Careful clinical examination and good communication with pediatric physicians help plan the appropriate imaging workup for such pediatric patients. Knowing the various imaging appearances of the many encountered disorders of the neck in children further helps diagnose and plan the most appropriate management. Read More

Dermoid cysts are a sequestration of ectoderm containing secondary skin structures, usually at characteristic locations of embryologic fusion lines. The midventral suprasternal fusion line is one such location in the developing embryo with both simple and complicated dermoids of this region reported in the literature. We reviewed our academic pediatric institutional experience with dermoid cysts of the suprasternal notch, focusing on the initial presentation as a palpable nodule referred for sonographic evaluation.
The purpose of this educational exhibit is to depict the ultrasound imaging features of suprasternal notch dermoid cysts in the pediatric population.
Secondary purposes are to describe the anatomy of the suprasternal notch, demonstrate CT and MR correlates of the these dermoids, and depict regional inflammatory complications. Read More

Medical imaging of the soft tissue of the neck or airway is one of the most common, and sometimes challenging, exams performed at a pediatric hospital. Imaging of the airway can help identify enlarged adenoids, the presence of a foreign body, an abscess, pathology or anatomical abnormality. It is crucial to understand the proper technique, breathing instructions and positioning in order to obtain optimal imaging for correct diagnosis. Different radiographic findings will be presented with examples of incorrect positioning, grid usage, exposure factors, artifacts and ways to improve the image quality. This poster will also provide technologists with tips and recommendations to help them to feel prepared and confident to work with all pediatric patients. Read More

Neck lesions are a common clinical scenario encountered in children. They can present as neck lumps or be discovered incidentally on medical imaging performed for other indications. While most paediatric neck lesions are benign, they can be a source of morbidity to patients and cause considerable anxiety to their care givers. Neck lesions in infants are made additionally more challenging as this area can be difficult to assess clinically. A clinically evident or suspected neck mass has, as a result, become a common indication for medical imaging in this age group. Being aware of the spectrum of neck lesions seen in infants and their respective imaging manifestations helps direct management appropriately in these cases.
A review of neck lesions seen in infants seen at a tertiary paediatric centre over the last two decades is presented with correlation of imaging findings across multiople modalities with the final diagnosis. Our aim is to provide an overview of both common and rare neck lesions seen in this age group by using broad categories of congenital, inflammatory and aggressive/malignant lesions. As well as showcasing cases with classic imaging findings we will include some cases where features overlapped between different varieties of neck lesions to illustrate pitfalls in imaging neck lesions in infants.

A neck mass is a frequent chief complaint in the pediatric population and includes a wide variety of etiologies. The age of the child, symptoms and physical exam findings may narrow the differential diagnoses. The radiologist can aid in diagnosis and management by guiding the selection of the appropriate imaging modality. It is important for the radiologist to recognize the features of common and rarer neck masses in children. This pictorial review will describe the multimodal imaging features of a variety of pediatric neck masses in four categories:
Thyroglossal duct cyst
Cervical extension of thymus
Fibromatosis colli Read More

Sinonasal tumors in the pediatric population are uncommon. Tumors affecting the nasal cavity and paranasal sinuses in children can arise from either soft tissue or bony structures and differ substantially from adult sinonasal masses. The aim of our exhibit is to review imaging features of a myriad of sinonasal neoplasms and tumor-like masses unique to the pediatric population ranging from the more well-known rhabdomyosarcoma and Ewing’s sarcoma to rarer lesions such as desmoplastic fibroma, nasal chondromesenchymal hamartoma, and melanotic neuroectodermal tumor of infancy.

Neck masses are commonly seen in the pediatric population and are a frequent reason for pediatric consults and can represent a diagnostic challenge. Although there is a broad spectrum of differentials, the vast majority of these lesions are benign, however malignant etiologies can also be encountered. Ultrasonography has become the first-line imaging modality in the evaluation of neck masses, given the ability to avoid radiation, wide availability and cost-effectiveness. Also, ultrasound represents an option when trying to avoid contrast administration or sedation.
The main teaching points of this exhibit will be:
1. Review variety of congenital and acquired neck masses in the pediatric patients.
2. Discuss imaging features and approach to various vascular, congenital abnormalities, benign and malignant tumors and other acquired abnormalities with Ultrasound.
3. Discuss the role of anatomic imaging in management.
A case-based pictorial review will be used to demonstrate:
1. Approach to vascular tumors and malformations based on clinical and imaging features including congenital, infantile hemangioma, low flow, various types of vascular malformations, locally aggressive lesions like kaposiform hemangioendothelioma, malignant tumors likely angiosarcoma and hemangioendothelioma.
2. Reviewing salient features of various congenital and acquired abnormalities including branchial cleft cysts, thyroglossal duct cysts, congenital goiter and midline frontal masses.
3. Discuss imaging features of other benign and malignant masses including teratomas, primary cervical neuroblastomas, soft tissue tumors (myofibroblastic), lipoblastoma. Also malignant tumors like fibrosarcoma, rhabdomyosarcoma.
4. Describe masses which mimic tumors such as fibromatosis coli and ectopic thymus.
5. Treatment and prognosis. Read More
