Parasagittal reformatted CT scan obtained through the jugular foramen shows curved line template for production of second reformatted image in the orthogonal plane (lines have been separated for clarity, but during the study, they were all grouped with the foramen).

A, Axial CT scan (study group, patient 5) shows bilateral jugular foramen stenosis and enlarged transosseous emissary foramina in a case of Apert syndrome. The patient has a ventriculoperitoneal shunt (curved arrow). B and C, Parasagittal reformatted CT scans of the same patient show narrowed and tortuous jugular foramina (arrows) (compare with Fig 4).
