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.

The authors aimed to assess the utility of gadolinium-based contrast agents in MR imaging performed for the evaluation of acute pediatric seizure presentation. In their study population, epileptogenic findings were found in 28% of patients, but gadolinium contrast was found to be of limited additive benefit in these patients.

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.
