Det pleomorfe adenom præsenterer sig som en fast, velafgrænset og langsomt voksende asymptomatisk hævelse. I nær-værende artikel præsenteres en 70–årig mand med et pleomorft adenom i kind-slimhinden, og de differentieldiagnostiske overvejelser diskuteres. Abstract En oversigt over den hyppigste spytkirteltumor Pleomorft adenom D

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.

Pleomorft adenom, diagnostik?

The epithelial component consists of an inner layer of epithelial cells, whereas the outer layer consists of myoepithelial cells that constitute the mesenchymal component. Both elements must be present for the diagnosis of pleomorphic adenoma to be made. In this context, MRI is a non-invasive method that may contribute to defining the diagnosis. 11 Areas with increased T 2 signal intensity have a high predictive value for the diagnosis of pleomorphic adenoma. 18 In addition, DWI has been described as a useful tool to obtain additional information on the function of salivary glands 19 and helps distinguish among different disorders.

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.

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. Pleomorphic adenomas, also known by the misnomer benign mixed tumors (BMTs), are benign epithelial neoplasms related to glandular tissue.

Pleomorphic adenoma (PA) is the most common salivary gland tumor. It most frequently occurs in the superficial lobe of the parotid gland, presenting as a solitary, slow-growing, painless mass. It may also arise in minor salivary glands throughout the head and neck region.

Coronal fat-saturated T2-weighted MRI demonstrates a hyperintense mass (pleomorphic adenoma) involving the deep lobe of the left parotid gland (arrow). The tumor has higher signal intensity than
