Inflammatory pseudotumors are clinocopathologically distinctive but biologically controversial entities. They have been described in the lungs, abdomen, retroperitoneum and extremities, but rarely affect the head and neck region. This report is of 2 cases of pseudo tumor of the paranasal sinuses with varied clinical presentation and successful outcome following treatment.

Objective: Our study aimed to update demographic profiles of sinonasal adenocarcinoma (SNAC) between 2000 and 2020, identify independent prognostic risk factors, and devise a predictive nomogram for overall survival (OS).
Methods: Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, cases of SNAC from 2000 to 2020 were analyzed for incidence trends. Univariate and multivariate Cox regression models helped pinpoint factors impacting patient survival.

Objective: Febrile neutropenia (FN) is a serious clinical event, associated with significant morbidity and mortality. Imaging has a central role in the identification of the fever cause. The study objectives were to assess abnormalities of potential infectious origin on paranasal sinus, chest and abdomen/pelvis CT scans performed during an episode of FN, in patients with or without specific clinical signs, and to evaluate their impact on the frequency of changes in treatment.

IgG4-related disease (IgG4-RD) is a systemic inflammatory condition characterized by tissue infiltration with IgG4-positive plasma cells and a tendency to form mass-like lesions in various organs. IgG4-related sinusitis, although a relatively rare manifestation of IgG4-RD, significantly impacts the paranasal sinuses. A 52-year-old man presented with persistent rhinorrhea, nasal obstruction, and headaches.

Infraorbital ethmoidal air cells (IOEAc) are ethmoidal cells that pneumatizes inferior to the orbital floor and lateral to a line parallel to the lamina papyracea. Studies have shown considerable anatomical variation with different extensions in humans. To identify and categorize the anatomical variations of the IOEAc creating a new, comprehensive variation classification system.
