Abstract
The aim of this study was evaluation of the role of multislice computed tomography in diagnosis of different temporal bone lesions.
This study included 50 patients (29 males and 21 females), with age ranging from 1 year to 70 years and the majority of patients were aged more than 41 years and less than 60 years (46%). All of them were subjected to full clinical history, ENT examination and radiological examination by MSCT.
Hearing loss was the commonest symptom seen in 52% of patients while 40% of patients presented with aural discharge which was the second most common symptom. Another symptoms also included in our study as headache, vertigo, fever and auricle deformity. Majority of cases had unilateral involvement (68%).
All data including site, size, relation to adjacent structures, various attenuation values, presence of soft tissue mass and the pattern of enhancement were collected and analyzed to establish the MSCT finding in different pathological groups. The diagnosis was correlated with clinical, surgical and pathological data.
According to final diagnosis, patients were classified into 4 groups: congenital (6), traumatic (7), inflammatory (28) and neoplastic (9).
CSOM is the most common finding and prevalent in all age groups particularly the patients in younger and middle age groups . The second most common finding was acquired cholesteatoma and affects mostly the patients age ranging from 25 to 45 years
