Post Traumatic ICA dissection-CT angiography

Clinical data: 26 year old female, trauma followed by right sided weakness.

Cerebral & extracerebral CT Angiogram: was performed utilizing axial source images using multislice CT and  were reconstructed with multiple intensity projection algorithms to yield MPR and 3D of the carotid system. 

Angiogram images particularly the reconstruction images show abrupt tapering of the contrast column of left ICA which is confirmed on the axial images as well just beyond the bifurcation. Initial portion of ICA shows true and false lumen and beyond which contrast column is not visualized. These findings are consistent with post traumatic left ICA dissection.
