(A) High-resolution computed tomography (HRCT) scan of the petrous bone showing a 5.4 mm left-sided large dehiscence of the SSC—Pöschl incidence. (B) 3D HR MRI of the labyrinth confirming a narrowing at 0.5 mm of the SSC (for a normal diameter of about 1.2 mm)—multiaxial 3D plane view; (C) Video Head Impulse test showing normal gains for all SCC. (D) Left-sided mixed hearing loss with an air-bone gap of 40 dB at 0.25 kHz. SSC, superior semicircular canal. 3D HR MRI, three-dimensional high-resolution magnetic resonance imaging.

(A) High-resolution computed tomography (HRCT) scan of the petrous bone showing a right-sided large dehiscence of the SSC coronal incidence (yellow arrow). (B) 3D HR MRI of the labyrinth confirming spontaneous and complete SSCD auto-plugging; multiaxial 3D plane view; (C) Video Head Impulse test showing normal gains for all SCC. (D) Right-sided hearing loss. SSC, superior semicircular canal. 3D HR MRI, three-dimensional high-resolution magnetic resonance imaging.
