Potential otogenic complications caused by cholesteatoma of the contralateral ear in patients with otogenic abscess secondary to middle ear cholesteatoma of one ear: A case report

Figure 1 Axial computed tomography scans showed cholesteatoma. A: The presence of soft tissue density in the right middle ear in 2018; B: A reduced soft tissue shadow in the mastoid cavity of the right ear and an increased soft tissue shadow in the mastoid cavity of the left ear with a bony defect of the temporal bone (arrow) in 2021.

Figure 2 Axial magnetic resonance imaging shows brain abscess. A: A low-intensity area encapsulated by the tan area, i.e., a high-intensity area, in the right temporal region (arrow) on April 30, 2018; B: No brain abscess was showed on June 7, 2018; C: No brain abscess was found on October 24, 2021.
