Objectives: Tympanic cavity (TC) is an anatomically challenging region for the diagnosis of lesions located inside it.Radiological diagnosis and demonstration of the anatomic localization of sporadic lesions such as vascular malformationsand meningocele are essential for the prevention of complications that may occur during operation and recurrent unnecessary interventions. The aim of the present study was to demonstrate the radiological appearance of the vascular variationsand the post-traumatic soft tissue lesions which are rarely encountered in TC. Methods: A total of 3525 temporal multi-slice computed tomography (MSCT) images were evaluated between 2010–2018.Twelve cases with non-inflamatory and non-neoplastic soft tissue lesions in TC were detected and 2 with meningocele wereincluded in the study. Results: Of the 12 cases, 6 were males and 6 were females. The mean age of the patients was 26.16 years. Four cases had anaberrant internal carotid artery (ICA), being bilateral in 2 cases and right sided in the remaining 2 cases. Six cases had dehiscentmega jugular bulb (DMJB); and 2 cases had post-traumatic meningocele. Conclusion: Vascular malformations and meningoceles are rarely observed in TC. They may present nonspecific clinical signsand symptoms; however, they should be evaluated with MSCT and MRI before the surgical interventions regarding the middle ear to prevent possible complications.
