Background: Inflammatory pseudotumors (IPTs) are rare, idiopathic, and inflammatory lesions that are histopathologically benign. Here, we present three cases of labyrinthine destruction caused by an IPT. Methods: The first patient was a 74-year-old male with a mass lesion extending from the inner ear to the external ear canal. The second patient was a 62-year-old female with a foliated polycystic lesion in the petrous bone on the dorsal side of the left internal auditory canal. The third patient was a 68-year-old female with a mass extending from the inner ear to the middle ear, destroying the semicircular canal and cochlea. Results: In two cases, we performed surgical resection successfully with no recurrence. In the other case, the lesion showed shrinkage after chemotherapy for colorectal cancer incidentally found during the examination process. Conclusion: Surgical technique and indication for IPT should be based on the location and function of the lesion. In addition, there is room to consider pharmacotherapy as a treatment option for IPT of the temporal bone. Level of Evidence: 4.
