Summary:

• Radiopaedia case ID: 43570
• Image ID: 20242384
• Image stack position: 52/73
• Plane projection: Coronal
• Aux modality: bone window
• Study description: CT Temporal bones (preoperative)
• Study findings: Marked enlargement of the left internal auditory canal presumably due to the presence of an acoustic neuroma, although no soft tissue windows have been performed. Cochlea and bony labyrinth are intact. Middle ear structures are normal. Right petrous temporal structures are normal (not shown). Note made of high riding jugular bulb bilaterally.
• Modality: CT
• System: Central Nervous System
• Findings: MRI demonstrates a solid heterogeneous tumor at the left cerebellopontine angle, enlarging and partially occupying the left internal acoustic canal, exhibiting vivid contrast enhancement and mass effect over the adjacent cerebellar peduncle and pons. The fourth ventricle is partially effaced, however there is no obstructive hydrocephalus.
