[Lipoma in the parotid gland: typical US and CT morphology].
Up to 3% of all parotid tumours are lipomas. Parotid lipomas can be diagnosed almost specifically by imaging as US, CT, MRI. On ultrasound parotid lipomas are ovoid, hypoechogenic lesions with typical feathered structure. Colour Doppler sonography did not detect any signals in the tumour. CT enables the definite diagnosis by measurement of density values equivalent to fat.
