    Abstract Interpretation of posttreatment imaging findings in patients with head and neck cancer can pose a substantial challenge. Malignancies in this region are often managed through surgery, radiation therapy, chemotherapy, and newer approaches like immunotherapy. After treatment, patients may experience various expected changes, including mucositis, soft-tissue inflammation, laryngeal edema, and salivary gland inflammation. Imaging techniques such as CT, MRI, and PET scans help differentiate these changes from tumor recurrence. Complications such as osteoradionecrosis, chondroradionecrosis, and radiation-induced vasculopathy can arise because of radiation effects. Radiation-induced malignancies may occur in the delayed setting. This review article emphasizes the importance of posttreatment surveillance imaging to ensure proper care of patients with head and neck cancer and highlights the complexities in distinguishing between expected treatment effects and potential complications.

    Abstract Objectives: Superior semicircular canal dehiscence (SSCD) is defined as a defect in the bone overly the superior semicircular canal (SSC). The purpose of this study is to evaluate the pre-operative imaging examinations of patients who have undergone SSCD repair. We hypothesize that these patients will not have a supralabyrinthine air cell on the side of surgery.
    Material and methods: Our group retrospectively reviewed 50 consecutive pre-operative computed tomography (CT) temporal bone examinations who had confirmed SSCD on intraoperative examination and underwent repair for the presence of a supralabyrinthine air cell.
    Results: 100% of patients who had confirmed SSCD on intraoperative examination had no supralabyrinthine air cell on pre-operative CT of the temporal bone.
    Conclusion: This study shows that a supralabyrinthine air cell is not present in SSCD. When a supralabyrinthine air cell is present, the roof of the SSC is intact. CT and magnetic resonance imaging (MRI) are often performed together to evaluate for SSCD and exclude other etiologies. We propose that if a supralabyrinthine air cell is seen on MRI, no CT is necessary, thus avoiding unnecessary radiation exposure and additional imaging costs to the patient.

    Abstract Laryngectomy and pharyngectomy are surgical options for advanced laryngeal or pharyngeal squamous cell carcinoma. Cervical osteomyelitis-diskitis, occurring when there is dehiscence of the posterior neopharyngeal wall, is an uncommon complication of laryngopharyngectomy. This case series describes imaging findings of pharyngoesophageal wall breakdown with subsequent cervical spine infection and demonstrates that most of these patients had undergone prior esophageal or neopharyngeal dilations for benign posttreatment stricture. Neck pain, fever, or serologic evidence of infection should prompt careful evaluation for osteomyelitis-diskitis and assessment for neopharyngeal breakdown and sinus tract formation, especially in the postdilation setting.

    Abstract Evaluation of lesions affecting the parotid gland is often challenging to both clinicians and radiologists. This article reviews parotid anatomy and function, as it relates to various lesions that may occur within the gland. Key morphlogic features of lesions are discussed with an emphasis on those that warrant biopsy and those that do not need biopsy. Various biopsy methods using ultrasound and computed tomography are reviewed.

    Abstract Purpose To evaluate the interrater reliability among radiologists examining posttreatment head and neck squamous cell carcinoma (HNSCC) fluorodeoxyglucose PET/contrast-enhanced CT (CECT) scans using Neck Imaging Reporting and Data System (NI-RADS). Materials and Methods In this retrospective study, images in 80 patients with HNSCC who underwent posttreatment surveillance PET/CECT and immediate prior comparison CECT or PET/CECT (from June 2014 to July 2016) were uploaded to the American College of Radiology's cloud-based website, Cortex. Eight radiologists from seven institutions with variable NI-RADS experience independently evaluated each case and assigned an appropriate prose description and NI-RADS category for the primary site and the neck site. Five of these individuals were experienced readers (> 5 years of experience), and three were novices (< 5 years of experience). In total, 640 lexicon-based and NI-RADS categories were assigned to lesions among the 80 included patients by the eight radiologists. Light generalization of Cohen κ for interrater reliability was performed. Results Of the 80 included patients (mean age, 63 years ± 10 [standard deviation]), there were 58 men (73%); 60 patients had stage IV HNSCC (75%), and the most common tumor location was oropharynx (
