Summary
Evaluating parotid gland lesions can be difficult. This review covers parotid anatomy, lesion features, and biopsy techniques to aid clinicians and radiologists in diagnosis.
Area of Science:
- Radiology
- Otolaryngology
- Pathology
Background:
- Parotid gland lesions present diagnostic challenges for clinicians and radiologists.
- Understanding parotid anatomy and function is crucial for evaluating associated pathologies.
Purpose of the Study:
- To review parotid gland anatomy and function in relation to various lesions.
- To discuss key morphologic features of parotid lesions to guide biopsy decisions.
- To review ultrasound and computed tomography-guided biopsy methods for parotid lesions.
Main Methods:
- Review of relevant anatomical and pathological literature.
- Discussion of imaging features of common and uncommon parotid gland lesions.
- Overview of ultrasound and computed tomography-guided biopsy techniques.
Main Results:
- Detailed description of parotid gland anatomy and its functional relevance.
- Categorization of parotid lesions based on imaging characteristics and likelihood of malignancy.
- Guidance on selecting lesions requiring biopsy versus those manageable with observation.
Conclusions:
- Accurate evaluation of parotid lesions requires integrating anatomical knowledge with imaging features.
- Morphologic assessment aids in determining the necessity of biopsy, optimizing patient management.
- Ultrasound and CT-guided biopsies are effective methods for tissue sampling of parotid lesions.

The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
