E2047. Diagnosing Various Head/Neck Lesions Based on Location and Understanding How Certain Lesions Correspond to Embryological Abnormalities
Staten Island University Hospital
Head and neck anatomy is a complicated topic with intricate and overwhelming details, rendering head and neck lesions a daunting task.Head and neck lesions can be categorized and characterized based on location, description, and patient demographic information. This educational exhibit will attempt to provide an overview of important head and neck anatomy and a framework for identifying common and uncommon head and neck lesions for the training and practicing radiologist.
Educational Goals / Teaching Points
The goals of this exhibit are to discuss the embryological development of the branchial arches and the notochord, as well as the migration of the thyroid gland; identify the normal anatomy of the head/neck region including various anatomical spaces such as the carotid, prevertebral, and retropharyngeal spaces; develop a short differential for lesions based on anatomic location within the head/neck region; discuss various radiology cases obtained from the author’s institution including CT and MRI that demonstrate various head/neck lesions, some of which are related to abnormal development of the branchial arches and notochord, or migration of thyroid gland; and discuss various head/neck tumors with radiology-pathology correlation.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit includes normal gross anatomy of the head/neck region including various anatomic spaces including carotid, prevertebral, and retropharyngeal; pictorial illustration of the branchial arches development, thyroid gland migration, notochord; cases of various cystic head/neck lesions with pictorial depiction of corresponding problems during embryological development such as branchial cleft cysts, thyroglossal duct cyst, chordoma, dermoid/epidermoid cyst, and ranula.
