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
