Review of the Major and Minor Salivary Glands, Part 2: Neoplasms and Tumor-like Lesions.

J Clin Imaging Sci 2018 15;8:48. Epub 2018 Nov 15.

Department of Imaging Sciences, University of Rochester Medical Center, Rochester, New York, USA.

The salivary glands are small structures in the head and neck, but can give rise to a wide variety of benign and malignant pathology. When this occurs, patients may present with palpable swelling, although it is quite common that they are asymptomatic and a salivary gland mass was discovered as an incidental finding on imaging performed for another reason. It is, therefore, critical that radiologists pay careful attention to the salivary glands and have working knowledge of the key differentiating features of the most common neoplastic and nonneoplastic etiologies of salivary gland masses.

Review of the Major and Minor Salivary Glands, Part 1: Anatomy, Infectious, and Inflammatory Processes.

J Clin Imaging Sci 2018 15;8:47. Epub 2018 Nov 15.

Department of Imaging Sciences, University of Rochester Medical Center, Rochester, New York, USA.

The major and minor salivary glands of the head and neck are important structures that contribute to many of the normal physiologic processes of the aerodigestive tract. The major salivary glands are routinely included within the field of view of standard neuroimaging, and although easily identifiable, salivary pathology is relatively rare and often easy to overlook. Knowledge of the normal and abnormal imaging appearance of the salivary glands is critical for forming useful differential diagnoses, as well as initiating proper clinical workup for what are often incidental findings.

Cross-sectional Imaging of Parotid Gland Nodules: A Brief Practical Guide.

J Clin Imaging Sci 2018 16;8:14. Epub 2018 Apr 16.

Department of Biomedical Sciences and Morphological and Functional Imaging, University of Messina, Policlinico "G. Martino", Messina, Italy.

Clinical evaluation and ultrasound examination are the first steps in the evaluation of a patient with a swelling of the parotid region. After the detection of a nodular lesion, cytological or histological confirmation is usually performed to achieve the diagnosis, while the choice of cross-sectional imaging (computed tomography scan and magnetic resonance imaging) may significantly vary from one physician to another, on the basis of the degree of confidence that both radiologist and surgeon have with this kind of imaging. This work focuses on some essential "reporting points" in cross-sectional imaging evaluation of parotid nodules, chiefly helpful to the radiologist when the ultrasonography assessment is considered incomplete and requires a further evaluation.

Diagnosis and Management of Piriformis Syndrome: A Rare Anatomic Variant Analyzed by Magnetic Resonance Imaging.

J Clin Imaging Sci 2018 21;8. Epub 2018 Feb 21.

Department of Radiology, David Grant Medical Center, Fairfield, CA, USA.

Piriformis syndrome is an uncommon condition that causes significant pain in the posterior lower buttocks and leg due to entrapment of the sciatic nerve at the level of the piriformis muscle. In the typical anatomical presentation, the sciatic nerve exits directly ventral and inferior to the piriformis muscle and continues down the posterior leg. Several causes that have been linked to this condition include trauma, differences in leg length, hip arthroplasty, inflammation, neoplastic mass effect, and anatomic variations. Read More
