- Cervical Osteomyelitis and Diskitis as a Complication of Neopharyngeal Breakdown: A Multisite Case Series Review
This case series of 11 patients status post laryngectomy/pharyngectomy describes the imaging findings of pharyngoesophageal wall breakdown with subsequent cervical spine infection. The authors show that MRI is more sensitive for spine infection in these patients presenting with neck, fever, and serologic evidence of infection.
- CT of the Larynx: Is an Additional High-Resolution Acquisition Necessary for Diagnostic Accuracy?
The purpose of this study was to determine whether reformatted laryngeal images derived from a standard neck CT acquisition can replace a separate dedicated high-resolution laryngeal acquisition. In 200 patients, the authors found a discrepancy in nearly one-quarter of the interpretations. Both up-staging and down-staging errors were made with the standard neck CT protocol and were critical in defining the optimal therapeutic approach. The authors concluded that the addition of focused images of the larynx after a second contrast bolus and a second acquisition sequence improves the radiologic staging of laryngeal tumors.
- Prevalence of Cochlear-Facial and Other Non-Superior Semicircular Canal Third Window Dehiscence on High-Resolution Temporal Bone CT
This study of 500 patients found the prevalence of non-SSCD on high-resolution CT in asymptomatic individuals to be 1.6% for CFD and 8.0% for JVD as compared with the rate in patients with audiologic or vestibular symptoms (2.9% for CFD and 7.8% for JVD). There was no statistically significant difference in the rates of radiologic findings between patients with reported symptoms suggestive of a possible third window syndrome and those without auditory or vestibular symptoms.
- MR Imaging Appearance of Ruptured Rathke Cleft Cyst and Associated Bone Marrow Enhancement
This clinical case series of 7 patients illustrates the imaging finding of enhancing basisphenoid bone marrow below the sella in cases of ruptured RCC. The mucin leaking out of the ruptured RCC can trigger a cascade of surrounding inflammation, which manifests as abnormal bone marrow enhancement.
- Differentiation between Chondrosarcoma and Synovial Chondromatosis of the Temporomandibular Joint Using CT and MR Imaging
As chondrosarcoma and synovial chondromatosis of the temporomandibular joint share overlapping clinical and histopathologic features, CT and MR imaging can be helpful to differentiate between the 2 entities. High-risk imaging features for chondrosarcoma include the following: lesion centered on the mandibular condyle, destruction of the mandibular condyle, no destruction/sclerosis of the articular eminence/glenoid fossa, infiltration into the tendon of the lateral pterygoid muscle, absent or stippled calcification, periosteal reaction, internal enhancement, and size of ≥30.5 mm.
- Update from the 5th Edition of the WHO Classification of Nasal, Paranasal, and Skull Base Tumors: Imaging Overview with Histopathologic and Genetic Correlation
This manuscript reviews the 2022 World Health Organization update on the head and neck tumor classification, emphasizing the importance of molecular data and genetic alterations in sinonasal neoplasms. It includes new entities and changes to the taxonomy and characterization of tumors.
- Performance of Neck Imaging Reporting and Data System (NI-RADS) for Diagnosis of Recurrence of Head and Neck Squamous Cell Carcinoma: A Systematic Review and Meta-analysis
Posttreatment follow-up imaging of head and neck cancer is challenging because of the anatomic complexity of the head and neck region and the operations and posttreatment effects of radiation and chemotherapy that mimic recurrent disease. The Neck Imaging Reporting and Data System (NI-RADS) provides standardized terminology, report structure, and evaluation categories to convey the degree of suspicion of recurrence in the interpretation of imaging studies. This meta-analysis found NI-RADS 3 (high suspicion) has a high diagnostic performance for detecting clinically significant recurrence.
