The left parotid gland is enlarged, with multiple diffuse tiny cystic lesions less than 4 mm in size. The gland parenchyma is hyperenhancing compared to the other side. Features are suggestive of juvenile recurrent parotitis.
Multiple bilateral enlarged upper cervical lymph nodes, with preserved oval shape and central fatty hilum, larger on left side, likely reactive upper cervical lymph nodes.
Normal MR appearance of the right parotid gland.
Mild enlarged nasopharyngeal adenoid, encroaching upon the nasopharyngeal airway.
Concentric mucosal thickening of both maxillary, right sphenoid sinuses and ethmoid air cells.
