Are Intraparotid lymph nodes normal?
It is common to see small normal intraparotid lymph nodes (IPLNs) on imaging studies, particularly on MRI (Fig. 74.1). Occasionally, reactive enlargement of IPLNs occurs, similar to reactive enlargement of neck nodes as seen in upper respiratory infections etc., mimicking parotid tumors [2].
Where are parotid lymph nodes located?
The parotid glands are located in front and beneath the ear. A duct, called Stensen’s duct, drains saliva from the parotid gland into the mouth, at the area of the upper cheeks. The submandibular glands are found on both sides, just under and deep to the jaw, towards the back of the mouth.
