ReviewNormal Vascular Structures and Variants on Head and Neck Imaging.
The vasculature of the neck, comprised of arteries and veins, provides for the supply and return of blood to and from the brain, and to structures of the neck and face. Knowledge of normal appearance and anatomy, and anatomic variants, may help one distinguish between normal and pathologic processes in the neck, which may affect diagnosis or choice of surgical approach. Other related structures that are important to recognize include the thoracic duct and carotid body. In this article examples of mostly computed tomography and MR imaging of normal anatomy and some of these variants are shown.

ReviewNormal Anatomic Structures, Variants, and Mimics of the Temporal Bone.
Various anatomic structures and variants in the temporal bone are potential radiological mimics and surgical hazards. The imaging features of normal variants and lesions with similar imaging appearance are presented in this article. Throughout the article, salient features that can help elucidate the distinguishing features between mimics and imaging pitfalls are presented.

Many different benign and malignant processes affect the central skull base and petrous apices. Clinical evaluation and tissue sampling are difficult because of its deep location, leaving imaging assessment the primary means for lesion evaluation. ⋯ It is important to be familiar with imaging appearances of common mimickers of malignant neoplasm in the skull base. This article familiarizes readers with imaging characteristics of various anatomic variants and benign pathologies that mimic malignant neoplasms, in hopes of increasing confidence of diagnosis, decreasing unnecessary procedures, and allaying patient fear.
