Summary:
- Radiopaedia case ID: 53541
- Image ID: 30379693
- Image stack position: 63/64
- Plane projection: Axial
- Aux modality: C+ arterial phase
- Study findings: CT angiogram of the brain. Left internal carotid artery dissection is better appreciated in this study. The left internal carotid artery demonstrates an abnormal vessel contour, with mildly narrowed distal segment surrounded by a non-enhancing crescent-shaped mural thrombus. The rest of the circle of Willis demonstrates normal enhancement. No other abnormality is seen.
- Modality: CT
- System: Central Nervous System
- Findings: CT brain study. No evidence of sulcal effacement, acute hemorrhage or ischemic changes within the brain. Ventricular pattern is appropriate for age. No acute fractures seen. The cervical segment of the left internal carotid artery demonstrates a narrowed lumen with a crescent-shaped hyperattenuating focus, favored to be a mural thrombus that extends towards the skull base. This is suspicious for acute left internal carotid artery dissection, especially given the presenting history.
