However, it is not a good test to diagnose other conditions like glomus tympanicum, PSA, glomus jugulotympanicum, or dehiscent jugular foramen, which can present as vascular retrotympanic lesions. MRA Head Without and With IV Contrast There is no relevant literature to support the use of MRA head without and with IV contrast for evaluation of PT when otoscopy shows a vascular retrotympanic lesion. MRA Head Without IV Contrast There is no relevant literature to support the use of MRA head without IV contrast for evaluation of PT when otoscopy shows a vascular retrotympanic lesion. Aberrant ICA can be diagnosed by MRA head without IV contrast. However, it is not a good test to diagnose other conditions like glomus tympanicum, PSA, glomus jugulotympanicum, or dehiscent jugular foramen, which can present as vascular retrotympanic lesions. MRI Head and Internal Auditory Canal With IV Contrast There is no relevant literature to support the use of MRI head and IAC with IV contrast for evaluation of PT when a retrotympanic lesion is suspected on otoscopy. MRI Head and Internal Auditory Canal Without and With IV Contrast The usual etiologies for vascular retrotympanic lesions are glomus tympanicum, glomus jugulotympanicum, aberrant ICA, PSA, and dehiscent jugular bulb. Small glomus tympanicum and glomus jugulotympanicum may be difficult to see on the MRI head and are easily seen on the CT temporal bone. There is no relevant literature to support the use of MRI head for detection of vascular variants that may present as vascular retrotympanic lesions. MRI Head and Internal Auditory Canal Without IV Contrast The usual etiologies for vascular retrotympanic lesions are glomus tympanicum, glomus jugulotympanicum, aberrant ICA, PSA, and dehiscent jugular bulb. Tiny glomus tympanicum may be difficult to see on the MRI head and are easily seen on the CT temporal bone. There is no relevant literature to support the use of MRI head for detection of vascular variants that may present as vascular retrotympanic lesions.
