Case 7

71 year-old man with history of slight headaches for few days presented with stroke and right-side weakness.

CT images show a cortical intraparenchymal hemorrhage on the left temporo-parietal area associated with more extensive hemorrhage of subdural space (Fig 1).

Sequence of oblique phlebograms of left internal carotid artery shows the absence of temporo-occipital vein (arrow) in the early venous phase (Fig 2), the delayed visualization in the middle venous phase (Fig 3), and the stasis of the same vein in the late venous phase (Fig 4). The vein of Labbe is absent, probably as an anatomic variant, and the temporo-occipital vein represents its substitution.
