They are the commonest bilateral or multifocal benign parotid tumor. They typically occur in the elderly (6 th decade), and twice as common in men (2.2:1) 11. Abstract Background and purpose: Pleomorphic adenoma is the most common parotid neoplasm. It has a relatively high rate of recurrence after surgery. Imaging features of recurrent parotid pleomorphic adenoma have been infrequently reported in the radiology literature. 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.

Pleomorphic adenomas, also known by the misnomer benign mixed tumors (BMTs), are benign epithelial neoplasms related to glandular tissue. They have a small but real risk of malignant transformation. For a discussion of specific sites of pleomorphic adenoma, please refer to.

They have a small but real risk of malignant transformation. For a discussion of specific sites of pleomorphic adenoma, please refer to pleomorphic adenoma of the salivary glands Pleomorphic adenomas of the salivary glands, also known as benign mixed tumors (BMTs), are the most common salivary gland tumors. The salivary glands are the most common site of pleomorphic adenomas. 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. Conclusion: 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.

Bosselated outer surface, often with tongue-like protrusions (pseudopods) Typically has 3 components: Epithelial (ductal) component forming the inner layer of cysts and tubules. Myoepithelial cells as the outer layer of cysts and tubules and scattered within the myxoid stroma. 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 a common benign salivary gland neoplasm characterised by neoplastic proliferation of parenchymatous glandular cells along with myoepithelial components, having a malignant potentiality. It is the most common type of salivary gland tumor and the most common tumor of the parotid gland. It derives its name from the architectural Pleomorphism seen by light microscopy.
