In order to avoid misdiagnoses, medical imagers should be familiar with the normal patterns and distribution of fluorodeoxyglucose (FDG) activity within the head and neck, as well as the pathophysiology and imaging-findings of common diagnostic pitfalls related to incidental FDG-avid lesions. The purpose of this article is to provide an image-rich review of the normal patterns of FDG uptake in the head and neck, help differentiate benign from malignant incidentally found FDG-avid foci, and detail important "don't miss" hypometabolic head and neck lesions on positron emission tomography/computed tomography and positron emission tomography/magnetic resonance imaging.

Isolated maxillary fungal pathologies involve a variety of clinical entities. These include invasive and non-invasive variants, where each has a unique pathogenesis, clinical manifestation, and approach for management. The aim of this case series is to investigate the several ways that fungal infections of the maxillary sinus might present, with the approach to diagnose and manage these conditions.

However, most simulators lack the ability to mimic the differing anatomic complexities between patients, such as variable external auditory canal (EAC) size. We developed a novel low-cost, medium-fidelity 3-dimensional-printed PET simulator with different EAC sizes to better reflect procedure complexity.

Background: Nivolumab paved a new way in the treatment of patients with recurrent or metastatic (RM) head and neck squamous cell carcinoma (RM-HNSCC). However, the limited rates of long-term survivors (< 20%) demand a robust prognostic biomarker. This nationwide multi-centric prospective study aimed to identify a plasma exosome (PEX) mRNA signature, which serves as a companion diagnostic of nivolumab and provides a biological clue to develop effective therapies for a majority of non-survivors.

Background: Extramedullary plasmacytoma (EMP) represents one of the rarer forms of plasma cell malignancies, capable of impacting a variety of tissues and organs throughout the body. The majority of EMP cases are predominantly found in the head and neck region, especially within the laryngopharynx, as well as in the gastrointestinal tract. While there have been documented instances of oropharyngeal involvement in EMP cases in the academic literature, it is important to note that EMP specifically affecting the uvula is exceedingly uncommon.
