On MRI, pleomorphic adenomas are usually well-circumscribed, homogeneous masses with low intensity on T1-weighted images and high intensity on T2-weighted images. They commonly have a rim of decreased signal intensity on T2-weighted images. Pleomorphic adenoma is the most common type of salivary gland tumour. Pleomorphic adenomas can arise in a variety of body sites including the skin and lungs although the vast majority arise in a type of salivary gland called the parotid gland. Pleomorphic adenomas are slow growing tumours although they can reach a large size without treatment.
