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. After gadolinium enhancement, the tumors are homogeneously enhancing unless they are large.

CT is often the first study ordered in patients with neck masses, and scans can show the mass and the retromandibular vein. Newer multisection CT scanners offer multiplanar capabilities rivaling that of MRI. Adenom, pleomorft Svensk definition.

Methods. A radiologic algorithm for the MRI diagnosis of PA was developed on the basis of five “high probability” criteria that all must be fulfilled for the MRI to qualify as a positive test result: bright T2-signal, sharp margins, heterogeneous nodular enhancement, lobulated contours, T2-dark rim.

Pleomorphic adenoma (PA) is the most common salivary gland tumor and is characterized by cytomorphological and architectural diversity. On CT and MR images, PAs are shown as well-defined lesions occasionally accompanied by characteristic lobulated contours.
It most frequently occurs in the superficial lobe of the parotid gland, presenting as a solitary, slow-growing, painless mass.
A “high probability” MRI is about 95% specific for pleomorphic adenoma. A subset of patients with MRI imaging that is highly suggestive of PA may reliably avoid further workup. The value of MRI in this setting is especially useful if preoperative fine needle aspiration is not readily available.

The value of MRI in this setting is especially useful if preoperative fine needle aspiration is not readily available. The salivary glands are the most common site of pleomorphic adenomas. On imaging, they commonly present as well-circumscribed rounded masses, most commonly located within the parotid gland, hypoechogenic on ultrasound, and bright on T2WI with homogeneous enhancement on MRI. Carcinoma ex pleomorphic adenoma is the most common of three malignant mixed tumors of salivary glands, and are thought to arise from pre-existing pleomorphic adenomas (or benign mixed tumors) 1.
