The author presents his own clinical case demonstrating the long stage and difficulties in diagnosing a rare tumor of the Ewing’s Family of Sarcomas in a young patient, due to the peculiarity of the course of the disease, manifested by a non-pathognomonic clinical pattern.

An otorhinolaryngologist must know the anatomy of the nasal cavity and paranasal sinuses prior to endoscopic surgery, because many structures cann’t be evaluated by him during visual and endoscopic examination. In this regard, all patients undergo computed tomography of the paranasal sinuses as a preoperative preparation, which allows not only to identify the pathological process, but also to assess anatomical features that may predispose to surgical complications. This review illustrates various anatomical variants of the nasal cavity and paranasal sinuses, which should be noted in the protocol and focus the attention of an otorhinolaryngologist on them in order to reduce the risk of possible surgical complications.

In this study, the impact of the availability and accuracy of the patient’s clinical, laboratory and anamnestic data on the conclusion of a radiologist was evaluated. To achieve this goal, three groups of protocols of 60 digital chest radiographs performed by five radiologists with different work experience were compared. At the first stage, a set of radiographs was provided without additional information, at the second stage — with reliable brief clinical, laboratory and anamnestic data and at the third stage - with unreliable data. As a result, it was shown that the availability of reliable and accurate clinical information is important for the interpretation of chest radiographs.
