[Show abstract][Hide abstract] ABSTRACT: The purpose of this study is to compare ultrasonographic evaluation, computerized tomography, MRI findings, with the pathological evaluation and staging of gallbladder cancer. Images of preoperative ultrasonography, CT and MRI combined with MR cholangiography from 40 patients with pathologically proven gallbladder cancer were correlated with histopathologic findings and operative findings.

[Show abstract][Hide abstract] ABSTRACT: Inverted papilloma is an uncommon epithelial tumor rising from the nasal vault, characterized by a high recurrence rate after surgery, and possibly associated squamous cell carcinoma, which may coexistent with the papilloma, or develop secondarily.
After a short overview of pathologic and clinical findings, we will access the different CT and MRI features of this tumor, emphasizing the interest of MRI in tumor mapping before extirpation, post operative recurrence and suggesting an associated or a secondarily developing carcinoma.

[Show abstract][Hide abstract] ABSTRACT: Our study's aim is to evaluate the reliability of computed tomography in diagnosis, extension and post-surgical follow-up of otosclerosis.
A group of 11 patients was examined during a period of 25 months from 2002 to 2004. All of them had clinically and audiometrically suspected otosclerosis with bilateral conductive hear loss in 7 cases (3 had surgical management), unilateral in 2, and mixed earing loss in 2. High resolution CT was performed once in 8 patients and twice in the 3 operated.
CT showed otosclerosis foci in all our study's patients, which was bilateral in 9 and unilateral in 2. The extension of the lesions varied from type IA to type 4B according to the otosclerosis staging.
Computed tomography is, so far, the most efficient imaging modality in otosclerosis, showing otosclerosis foci when the clinical features are doubtful, allowing an accurate extension of the lesions and detecting complications during post-surgical follow-up.
