Background: Sinonasal carcinomas are rare. The purpose of this study was for us to present our assessment of the effects of retropharyngeal lymph node involvement at diagnosis on patient outcomes.
Methods: Retropharyngeal lymph node involvement in 36 patients with sinonasal carcinoma was determined by radiology at initial presentation. Clinical outcome, in particular, overall survival (OS) and locoregional control, was assessed by Kaplan-Meier analysis and log-rank testing.
Results: Retropharyngeal lymph node involvement was associated with statistically significant decreased OS (P = .0066) in the patient collective. In the squamous cell carcinoma (SCC) subgroup (n = 23), decreased OS (P = .0046) and worse locoregional control (P = .0065) were observed. In these patients, decreased OS (P = .0423) and worse locoregional control (P = .0315) were also seen in the advanced tumor subgroup.
Conclusion: Retropharyngeal lymph node involvement at diagnosis is a significant prognostic factor for decreased OS and locoregional control in sinonasal carcinoma.

Introduction: The objective of this study is to estimate reference values for medial retropharyngeal lymph nodes (MRLNs) measured in high-field (3T) MRI studies of the canine head/brain using transverse T2 spin-echo images and to determine if dogs with structural brain disease exhibit medial retropharyngeal lymph nodes that are larger than expected from estimated reference values.
Methods: The study population comprises 142 MRLNs from 71 dogs with no evidence of structural brain disease and normal CSF evaluation and 116 MRLNs from 58 dogs with structural brain disease confirmed by histopathology as of infectious or neoplastic origin, or to represent meningoencephalitis of unknown etiology.
Results: Based on this sample, MRLNs are expected to measure 2.

Purpose: To establish an artificial intelligence (AI)-empowered multistep integrated (MSI) radiation therapy (RT) workflow for patients with nasopharyngeal carcinoma (NPC) and evaluate its feasibility and clinical performance.
Methods And Materials: Patients with NPC scheduled for MSI RT workflow were prospectively enrolled. This workflow integrates RT procedures from computed tomography (CT) scan to beam delivery, all performed with the patient on the treatment couch.

Background: Due to the rarity of sinonasal squamous cell carcinoma (SNSCC), the distribution patterns of lymph node metastasis (LNM), the relationship between LNM and prognosis, and the optimal treatment of LNM lack sufficient evidence-based support.
Objectives: To investigate the patterns of LNM in SNSCC and evaluate the impact of LNM on prognosis.
Design: This was a retrospective cohort study.

Background: Chronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy in cervids. The disease is caused by a pathogenic prion, namely PrP. Currently, diagnosis of CWD relies on IHC detection of PrP in the obex or retropharyngeal lymph nodes (RPLN) or ELISA screening of obex and RPLN followed by IHC confirmation of positive results.

Background: Age-specific normal measurements or specific size criteria for retropharyngeal lymph nodes in children have not been defined.
Objective: We aimed to determine the normal measurements and distribution of retropharyngeal lymph nodes on three-dimensional magnetic resonance imaging (3-D MRI) in children.
Materials And Methods: In this retrospective study, we included 440 patients (213 girls) aged 0-17 years who were admitted to our center with seizures and headaches and underwent brain and neck MRI with T2-sampling perfection with application-optimized contrasts using different flip angle evolution sequences.
