Rare Non-Tumor Diseases of the Pharynx and Larynx

Abstract

Some inflammatory systemic and non-systemic diseases of the pharynx and larynx can clinically simulate the course of the tumor process. In these cases, the computed tomography method provides a comprehensive examination of patients, significantly adding information to the endoscopic picture. 4 clinical cases are presented, united by common aspects: suspicion of a tumor process and the absence of typical computed tomography symptoms characteristic of a tumor lesion. IgG4-related sclerosing disease, rheumatoid arthritis, amyloidosis and actinomycosis are rare conditions, however they should be included in the differential diagnosis. In this regard, knowledge of the radiation characteristics of these rare nosological forms will be useful to a practicing specialist.
