КЛИНИЧЕСКИЙ СЛУЧАЙ ХОНДРОМИКСОИДНОЙ ФИБРОМЫ ВИСОЧНОЙ КОСТИ, СИМУЛИРУЮЩЕЙ ХРОНИЧЕСКИЙ ВОСПАЛИТЕЛЬНЫЙ ПРОЦЕСС

Abstract

Purpose: To present a clinical case of a benign bone tumor of rare localization – chondromyxoid fibroma of the temporal bone, simulated chronic inflammation. Material and methods: A clinical case of chondromyxoid fibroma of the right temporal bone is presented. X-ray computed tomography (CT) and magnetic resonance imaging (MRI) of the temporal bones were performed before and during hospitalization. Results: Patient T., 29 years old, has been complaining about discomfort, congestion and noise in the right ear for the past 10 years without clear history of acute media otitis in anamnesis. According to the results of MRI of the temporal bones, a tumor of the right temporal bone was revealed. To clarify the diagnosis and for surgical treatment, the patient was referred to the clinic. During hospitalization CT of the temporal bones with contrast enhancement was performed and a tumor in the mastoid process of the right temporal bone with a ring-shaped accumulation of a contrast was determined, differential diagnosis included tumor and chronic abscess. According to the results of morphological examination after radical surgery of the temporal bone, chondromyxoid fibroma was diagnosed. Conclusion: Localization of chondromyxoid fibroma in the temporal bone is extremely rare and having by chance some features can simulate chronic inflammatory process. The absence of a clear history of acute otitis allows more likely suggest the tumor.
