Purpose: Cochlear implantation has transformed the management of pediatric sensorineural hearing loss, and the number of children receiving implants in the United States has continued to increase over the past decade. Many of these children will require subsequent imaging, either for implant complications or unrelated concerns and pediatric imagers must be familiar with the appearance, potential complications, and imaging limitations of these devices. This educational exhibit will review key imaging considerations in postoperative cochlear implant evaluation, MRI safety updates and artifact considerations relevant to pediatric radiologists. Content Outline / Learning Objectives: - Brief overview of Cochlear Implant Devices: Understand the components of the device, particularly options for the magnet component, and where the =implant should normally be placed. - Discuss postoperative imaging findings and complications, including electrode malposition, migration and infection. - Summarize MRI safety considerations for patients with older and newer cochlear implant (CI) models, highlighting the impact of magnet design and concerns for image quality.

Branchial apparatus anomalies (BAA) due to aberrations in the development and involution of the branchial apparatus can present as a cyst, fistula, or sinus tract. Definitive treatment for a BAA is complete surgical excision. The embryology of BAA has been well described, but few reports in the published literature discuss optimally imaging these patients. The purpose of this study is to describe the CT and MR imaging findings of BAA, and to correlate the imaging findings with surgery and pathology results. The goal is to develop a standardized imaging approach and search pattern specific to each subtype of BAA that would answer the most pertinent clinical questions for surgical planning. Read More

This review describes the CT and MRI features of developmental variants and pathological lesions that involve the skull base, excluding those centered in the nasal cavity, nasopharynx, sinuses and orbits. Normal anatomy of developing bony skull base will be illustrated. The lesions are categorized by pathology rather than locations, and the following entities will be covered. Congenital and developmental lesions - arrested pneumatization, aberrant arachnoid granulations, dermoid/epidermoid cysts, ecchordosis physaliphora, encephaloceles, persistent craniopharyngeal canal Inflammatory/Infectious lesions - skull base osteomyelitis, petrous apicitis, cholesterol granuloma Benign lesions - Fibrous dysplasia, aneurysmal bone cyst, osteoma, osteochondroma, meningioma Malignant lesions - Langerhans cell histiocytosis, lymphoma, neuroblastoma metastasis, Ewing’s sarcoma, osteosarcoma, chordoma, chondrosarcoma Read More
