Benign tumors of the liver

چکیده
Benign liver tumors are common in general population, can be seen in 9% to 20% of individuals. Some of these tumors have a completely benign natural history and do not need to be resected, while others carry a risk of growth, hemorrhage, or malignant transformation and should be operatively removed. Obtaining a preoperative diagnosis is therefore critical, and this single factor remains the primary challenge in managing patients with benign tumors of the liver. This article gives basic information about hemangioma, liver cell adenoma, focal nodular hyperplasia, and less common lesions that arise from the hepatic epithelial or mesenchymal tissues.

متن کاملDynamic Contrast Magnetic Resonance Imaging (DCE-MRI) and Diffusion Weighted MR Imaging (DWI) for Differentiation between Benign and Malignant Salivary Gland Tumors
Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...
