case_images: A pure-tone audiogram revealed conductive hearing loss of 30 dB(Figure 1).
case_images: Magnetic resonance images. The tumour was detected as a 2.3 x 2.1 x 1.8 mm mass in the EAC, with low signal intensity on T1-weighted, high signal intensity on T2-weighted, and homogeneous enhancement on gadolinium-enhanced T1-weighted images. (a) Transverse section of a T1-weighted image. (b) Transverse section of a T2-weighted image. (c) Transverse section of a gadolinium-enhanced T1-weighted image. (d) Coronal section of a gadolinium-enhanced T1-weighted image.

case_images: T1-weighted, high signal intensity on T2-weighted, and homogeneous enhancement on gadolinium-enhanced T1-weighted images (Figure 2). There was no connection with the parotid gland and no invasion of the middle ear.
case_images: Histopathological section of the tumour. Histopathological examination of haematoxylin and eosin (HE) stained sections revealed a partly encapsulated tumour exhibiting proliferation of myoepithelial cells with foci of ductal differentiation associated with myxoid and hyalinized matrix material (x40).
