Pleomorphic Adenoma-MRI
This 22 year old male shows a relatively defined lesion in the superficial lobe of parotid measuring 2.0 x 1.7cm appearing hypointense on T1 weighted images and hyperintense on T2 and STIR images. There is inhomogenous post contrast enhacement. Deep lobe of parotid is not involved. Neurovascular planes are preserved. Planes with underlying masseteric muscles are maintained. 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.
