Head and neck CT is classically seen as a multiloculated (80%), expansile "soap-bubble" lesion, with well demarcated borders and no matrix calcification. Occasionally erosion of the adjacent tooth roots can be seen which is highly specific. When larger it may also erode through cortex into adjacent soft tissues.<ref name="radio">  Salivary gland tumors.
