Figure 4. — Cerebral multidetector computed tomography-angiography. (A) Coronal plane reconstruction shows a regular length and course of the right styloid process (SP; arrow). (B) The left SP (arrow) shows a longer length than the norm. (C) Sagittal plane reconstruction shows the left SP (short arrow) compressing the left internal jugular vein (LIJV; arrow heads) against the transverse process of C1 (long arrow). (D) In the axial acquisitions after contrast medium injection, the left transverse venous sinus does not show enhancement because it is thrombotic (long arrow), while the contralateral transverse venous sinus is impregnated by contrast medium (short arrow). (E) Thrombosis of the left transverse sinus (long arrow) is also well highlighted in the coronal plane reconstructions, which show normal impregnation of the right transverse venous sinus (short arrow).
