case_images: Computed tomography scan (CT scan) revealed the soft tissue mass without bony erosion or involvement of the middle ear and appeared to originate from the inferior external canal wall (Figure 2).
case_images: The MR findings: the mass measuring 10X10 mm showed a homogenous, iso signal intensity on a both T1- and T2-weighted image.

case_images: Magnetic resonance imaging (MRI) showed that the mass measuring 10 x 10 mm showed a homogenous, iso signal intensity on a both T1- and T2-weighted image (Figure 3).
case_images: Microscopically, specimen demonstrated xanthogranuloma in the external auditory canal (hematoxylin and eosin, 100X).

case_images: fig4
case_images: This is a multinucleated cell with a peripheral ring of nuclei and a glassy, eosinophilic cytoplasm. This histopathologic examination is compatible with xanthogranuloma (Figure 4).
