The purpose of this paper is to present a user-friendly reference for 24 of the most common normal variants of the osteomeatal unit. A five image set of consecutive normal coronal hanging head computed tomography (CT) images was obtained. Half of each image was duplicated enough times to allow superimposition of the variants. For organizational purposes,(More)
This article discusses the normal anatomy and pathologic entities that involve the lower cranial nerves. Normal anatomy is described and correlated with line diagrams and MR images. Distinct pathologic processes that involve the individual nerves along their various components are discussed. The imaging characteristics of these lesions are provided.(More)
The origination and course of the glossopharyngeal, vagus and accessory cranial nerves explains their function and localizes pathology. Abnormalities of these lower cranial nerves may be intrinsic or extrinsic and is due to a multiplicity of disease processes. The clinical presentation of the involved cranial nerve helps to guide imaging evaluation.(More)
