Classical anatomists have provided detailed description of the arterial collateral pathways found in the head and neck. The small branches building this intricate network are difficult to access. The arterial…
Carotid cavernous fistulas (CCFs) are abnormal communications between the carotid arterial system and the cavernous sinus. CCFs are broadly classified as either direct or indirect. Surgical treatment of CCFs is…
Cervical arterial dissections and dissecting aneurysms are relatively rare pathologies, but can be associated with significant morbidity from ischemic complications. We review the challenges in diagnosing cervical arterial dissections, their…
Head and neck high-flow vascular malformations are uncommon lesions whose management presents a clinical challenge. Although in some rare cases a complete cure is possible, in the vast majority the…
Juvenile nasopharyngeal angiofibromas and paragangliomas are the most common hypervascular tumors of the head and neck that require embolization as an adjunct to surgery. A detailed understanding of the functional…
Recent technologic advances including multidetector CT, dynamic CT angiography, high-field MR imaging, four-dimensional MR angiography, and physiologic studies, such as perfusion imaging, have revolutionized the imaging work-up of head, neck,…
Patients with recurrent head and neck cancer have poor quality of life and suffer dismally from debilitating symptoms. Ablative techniques offer patients an alternative, minimally invasive treatment option. As a…
Use of image-guidance allows safe and precise percutaneous placement of needles for various diagnostic and therapeutic procedures in the head and neck region. This review describes the anatomy relevant to…
This article reviews the embryology, anatomy, congenital anomaly, acquired disorders, degenerative diseases, neoplasms, and inflammatory and infectious disorders in the craniovertebral junction. The imaging characteristics and differential diagnoses of these…
Interpreting CT or MR imaging examinations performed on patients with a history of middle ear, mastoid, or neurotologic surgery can be challenging. This is greatly simplified by knowing the surgical…
