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…
Jugular foramen, albeit complex, is essentially a bony conduit transmitting nerves and vessels from the posterior cranial fossa to the nasopharyngeal carotid space. In addition to its intrinsic pathologic conditions,…
The petrous apex is the most medial portion of the temporal bone that cannot be directly examined on clinical examination. The referring physician completely relies on imaging and radiologic interpretation….
This article describes the rationale, indications, and modality for intraoperative brain mapping for safe and effective surgical removal of tumors located within functional brain areas. Intraoperative mapping refers to a…
A variety of congenital, traumatic, vascular, inflammatory, and neoplastic processes may affect the facial nerve. Prudent use of CT and MR imaging combined with a complete understanding of facial nerve…
This article briefly discusses the imaging approach to lesions of the anterior skull base. A brief review of normal anatomy and imaging techniques is followed by a discussion about common…
Pathologic processes within the cerebellopontine angle (CPA) may present because of mass effect on local structures or on the pons or cerebellum. MR imaging is superior to CT for evaluation…
The central skull base (CSB) constitutes a frontier between the extracranial head and neck and the middle cranial fossa. The anatomy of this region is complex, containing most of the…
Inflammatory and infectious diseases of the temporal bone are a major indication to perform high-resolution CT and MR imaging studies. Such studies allow one to evaluate the extent of the…
