Summary:
- Radiopaedia case ID: 33045
- Image ID: 10001262
- Image stack position: 7/46
- Plane projection: Coronal
- Aux modality: non-contrast
- Modality: CT
- System: Central Nervous System
- Findings: A round, homogeneous extra-axial mass centered on the right cerebellopontine angle displaces the pons and the middle cerebral peduncle to the left and distorts but does not efface the fourth ventricle. The mass enhances homogeneously and vividly. There is minimal extension into the right porus acusticus and minimal widening of the right internal auditory canal compared to the left. No underlying hyperostosis. No other enhancing lesions identified. No hydrocephalus. No intra or extra axial hemorrhage. No evidence of acute ischemia. Conclusion: Appearances of the right cerebellar pontine angle mass are those of either a meningioma or acoustic neuroma. On the basis of this CT it is difficult to distinguish between the two.
