Basilar skull fractures are a relatively frequent occurrence in significant head trauma, and their detection is important, as even linear nondisplaced fractures can be associated with critical complications. The management of skull base fractures depends on the location and extent of these associated complications. This article reviews skull base anatomy;(More)
BACKGROUND Spontaneous cerebrospinal fluid (CSF) leaks are largely attributed to idiopathic intracranial hypertension and typically present as skull base defects with or without prolapse of intracranial contents. However, in our practice, we have encountered a distinct type of spontaneous CSF leak that presents in a different manner. OBJECTIVE To discuss(More)
BACKGROUND Workup of cerebrospinal fluid (CSF) leaks can be challenging. Patients with intermittent or infrequent clear rhinorrhea that cannot be collected, those with questionable or multiple skull-base (SB) defects on imaging, and those with previous SB surgery can present diagnostic dilemmas. In this patient population, radiologic studies that allow(More)
Laryngeal carcinoma is a devastating malignancy that severely affects patients' quality of life, with compromise of ability to talk, breathe, and swallow. Accurate tumor staging is imperative, because treatment plans focus on laryngeal conservation therapy whenever possible. Although the mucosal extent of tumor and vocal cord mobility is best assessed with(More)
BACKGROUND AND PURPOSE The Head and Neck Imaging Reporting and Data System (NI-RADS) surveillance template for head and neck cancer includes a numeric assessment of suspicion for recurrence (1-4) for the primary site and neck. Category 1 indicates no evidence of recurrence; category 2, low suspicion of recurrence; category 3, high suspicion of recurrence;(More)
PURPOSE The purpose of this article is to demonstrate the role of the ACR Dose Index Registry(®) (DIR) in a dose reduction program at a large academic health care system. METHODS Using the ACR DIR, radiation doses were collected for four common CT examination types (head without contrast, chest with contrast, chest without contrast, and abdomen and pelvis(More)
There are a myriad of head and neck pathologies that extend from the extracranial to the intracranial compartment, traversing the skull base, and knowledge of the imaging appearance of this pathology is critical to practicing neurosurgeons. This article reviews some of the important inflammatory or acquired head and neck pathology along the skull base,(More)
BACKGROUND AND PURPOSE The increasing impact of diagnosing extracapsular spread by using imaging, especially in patients with oropharyngeal squamous cell carcinoma, highlights the need to rigorously evaluate the diagnostic accuracy of imaging. Previous analysis suggested 62.5%-80.9% sensitivity and 60%-72.7% specificity. Our goals were to evaluate the(More)
As the obesity epidemic grows in the United States, rhinorrhea and otorrhea from spontaneous cerebrospinal fluid (CSF) leaks secondary to untreated idiopathic intracranial hypertension are increasing in prevalence. CSF rhinorrhea and otorrhea should also be carefully evaluated in posttraumatic and postsurgical settings, because untreated CSF leaks often(More)
