BERRA, Paola et al. Pediatric pathology of temporal bone: characteristic tomographic findings. Rev. argent. radiol. [online]. 2012, vol.76, n.2, pp.133-141. ISSN 1852-9992.

The temporal bone is the seat of frequent otologic disorders in children. Objective. To report the statistics and description of characteristic computed tomography (CT) findings of temporal bone pathology in a pediatric population. Material and Methods. Retrospective, longitudinal and descriptive review of 64 medical records taken between January 2008 and April 2011 at the Pediatric Hospital Pedro Elizalde. The classification of diseases was: inflammatory (infectious and noninfectious), congenital, histiocytosis, tumor infiltration and traumatic. Results. Males: 64%, age range: 1 month to 14 years (mean: 6.1 years). We found 53% inflammatory infectious conditions, 36% inflammatory noninfectious, 4.6% congenital, 1.5% histiocytosis, 3% tumor infiltration, and 1.5% traumatic. Infections disease was the most prevalent pathology in children under 5 years (otomastoiditis 43.6%). Cholesteatoma constituted the major non-infectious inflammatory condition in the age range from 6 to 14 (36%). Neoplasms were represented by secondary infiltration of nasopharyngeal angiofibroma or neuroblastoma metastasis. Conclusion. Acute otomastoiditis and cholesteatoma were the most common otologic pathology in the pediatric population and require CT. In the cases reviewed, CT diagnosis was consistent with clinical, surgical and / or pathology findings.
