Abstract
Tympanomastoidectomy operations were done for 63 patients with active chronic suppurative otitis media (CSOM). Preoperattve computed tomography (CT) scanning and magnetic resonance imaging (MRI) were performed for all. The CT findings of abnormal soft tissue density associated with bone erosion were 100% specific to the surgical findings of choles-teatoma. Fifty percent (27/54) of patients that had abnormal soft tissue on CT scan in attic area were accompanied by osseous necrosis of malleus head and incus body. It was not possible to diagnose or exclude cho-lesteatoma on the basis of CT findings alone. CT and MRI were absolutely specific (100%) in detection of soft tissue in attic area, mesotympa-num, and mastoid cavity but less sensitive in differentiation of cholesteatoma from any other soft tissue masses in chronic ear disease. There was a positive significant correlation between CT (or MRI) findings when compared to the surgical findings (P<0.05). Also CT and MRI were significantly correlated (P<0.05), Hyper-intensity in T1w images makes the diagnosis of lateral sinus thrombophlebitis more conclusive. In our series both CT and MRI were of parallel sensitivity in diagnosing brain abscess with actual cavities.
