Sinonasal (Schneiderian) Tumors in the Temporal Bone: Case Series and Systematic Review [HEAD AND NECK IMAGING]

CONCLUSIONS:
The observed tumor patterns support the hypothesis that the Eustachian tube facilitates the spread of sinonasal epithelium–derived neoplasms from the sinonasal cavity to the temporal bone. Transtubal spread of sinonasal epithelium–derived neoplasms should be considered among the rare causes of middle ear masses.
