Eustachian tube teratoma: A case report

Figure 3 Magnetic resonance imaging of the patient’s head and neck. A, D, G: Three-dimensional (3D) T2 weighted image (WI); B, E, H: Fat suppression (FS) 3D T1WI; C, F, I: FS 3D T1WI with contrast (C+); A-C: Magnetic resonance (MR) images in the transverse plane showed the part of the mass which was a homogeneous lesion with slightly higher signal intensity and with enhancement (white arrowheads) in the tympanum and external auditory canal; D-F, G-I: MR images in the transverse plane showed the part of the mass which was a well-defined, homogeneous lesion with high signal intensity along the left eustachian tube (white arrowheads), and on FS 3D T1WI, a lesion with decreased signal intensity consistent with macroscopic fat and with a contrast-enhancing rim (black arrowhead) was seen.
