Title
CT Petrous/Temporal Bone Without Contrast
Clinical History
Patient-specific — populated from user input at report time. Shows "None" if not provided.
Comparison
No prior studies available for comparison.
Technique
CT of the petrous temporal bone was performed without intravenous contrast using contiguous thin-section axial images. Sagittal and coronal multiplanar reformats were generated.
Findings
Bilateral temporal bone examination demonstrates normal findings.
Right Temporal Bone - Tympanic Membrane:
The right tympanic membrane is normal in appearance.
Right Temporal Bone - Middle Ear Cleft:
No soft tissue or fluid is identified in the right middle ear cleft.
Right Temporal Bone - Prussak's Space:
There is no abnormal soft tissue within the right Prussak's space.
Right Temporal Bone - Ossicles:
The right ossicles are normal in appearance and alignment.
Right Temporal Bone - Bony Labyrinth:
The right bony labyrinth is normal in appearance.
Right Temporal Bone - Vascular Course:
There is no aberrant course of the right internal carotid artery or descending jugular bulb.
Right Temporal Bone - External Auditory Canal:
The right external auditory canal is patent.
Left Temporal Bone - Tympanic Membrane:
The left tympanic membrane is normal in appearance.
Left Temporal Bone - Middle Ear Cleft:
No soft tissue or fluid is identified in the left middle ear cleft.
Left Temporal Bone - Prussak's Space:
There is no abnormal soft tissue within the left Prussak's space.
Left Temporal Bone - Ossicles:
The left ossicles are normal in appearance and alignment.
Left Temporal Bone - Bony Labyrinth:
The left bony labyrinth is normal in appearance.
Left Temporal Bone - Vascular Course:
There is no aberrant course of the left internal carotid artery or descending jugular bulb.
Left Temporal Bone - External Auditory Canal:
The left external auditory canal is patent.
Impression
Unremarkable bilateral petrous and temporal bone CT.
