## Overview[edit | edit source]

Head and neck CT scan may be diagnostic of salivary gland tumors. Findings on CT scan suggestive of salivary gland tumors include bony, local and, perineural invasion, and lymph node metastasis.[1][2]

## CT[edit | edit source]

* Head and neck CT scan assesses the extent of a salivary gland tumor, which is greater than can be appreciated on physical examination. It also assesses the size and location of the salivary gland cancer. Head and neck CT scan is useful to evaluate bony, local and, perineural invasion and lymph node metastases.
* CT scan is also useful to assess the parapharyngeal space for involvement from lesions in the parotid.[1][2]
* CT best identifies temporal bone or mandibular destruction.
* In addition, CT scan can provide anatomic details that are useful for surgical planning.
