A Axial cut contrast-enhanced CT head and neck showing hypodense non-enhancing well circumscribed lesion measuring (1 × 1 × 0.5 cm) at the nasopharyngeal opening of left ET. B Reconstructed sagittal CT scan head and neck showing the lesion at the level of the left ET orifice protruding into the nasopharynx (arrow). C Axial T1-weighted MRI without contrast with fat suppression showing hypointense density, homogeneous to fat signal, lesion at the nasopharyngeal orifice of the ET. D Axial T2-weighted MRI without fat suppression showing the fluid signal in the left mastoid area suggesting severe middle ear effusion and the lesion showing hyperintense signal at the nasopharyngeal opening of the left ET (arrow). Notice the bulky tail of the inferior turbinate. E Coronal T1-weighted MRI without contrast without fat suppression showing hyperintense signal lesion at the nasopharyngeal opening of the left ET. F Sagittal T1-weighted MRI without contrast without fat suppression showing hyperintense signal lesion at the nasopharyngeal opening of the left ET protruding into the nasopharynx (arrow)
