Abstract The skull base is made of flat bones that separate the intracranial compartment from the extracranial head and neck. Owing to this unique location, it can be affected both…
Abstract The jugular foramen is a complex skull base foramina containing important neurovascular structures that can be directly evaluated only by CT or MR imaging. Thus it is important to…
Abstract The cerebellopontine angle (CPA) cistern is a subarachnoid space centered within the posterior cranial fossa at the level of the internal auditory canal and bordered medially and laterally by…
Abstract Petrous apex abnormalities are usually incidentally detected on imaging for unrelated symptoms. Their deep location precludes direct clinical examination and easy percutaneous biopsy. Therefore, the radiologist plays a key…
Abstract Temporal bone fractures are divided into longitudinal and transverse fractures, each with their particular clinical features. Transverse fractures mainly cause conductive hearing loss, whereas longitudinal fractures almost invariably cause…
Abstract Neurointerventional radiology has many applications in the skull base. We focus on preoperative embolization to hypervascular tumors and embolization of the vascular lesion, in a hope to keep in-depth…
Abstract Facial nerve dysfunction can occur from a variety of causes, including congenital, inflammatory, traumatic, vascular, and neoplastic processes. Imaging plays an important role in the evaluation of facial nerve…
Abstract Interpretation of 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…
Abstract The endoscopic endonasal approach has become the preferred surgical approach to many tumors of the ventral skull base, both benign and malignant. This approach represents an amalgamation of various…
Abstract Imaging is recommended only in the aggressive so-called necrotizing variant of external otitis, seen in diabetic patients. Acute otomastoiditis and coalescent mastoiditis with subperiostal abscess formation are almost exclusively…
