Article Figures & Data
Figures
- Fig 1.
MR images of right JFM obtained in a 46-year-old woman (patient 6).
A, B, Transverse T1-weighted images (400/9).
C, D, Transverse T2-weighted images (4,100/90).
E, F, Transverse postcontrast T1-weighted images (400/20).
MR signal intensity of the intracranial component (arrow in A, C, and E) for JFM is higher than that of the extracranial component (arrow in B, D, and F) on T1-, T2- and postcontrast T1-weighted images.
- Fig 2.
MR images of left JFM obtained in a 48-year-old woman (patient 7).
A, B, Transverse T1-weighted images (500/15).
C, D, Transverse T2-weighted images (4,000/100).
E, F, Transverse postcontrast T1-weighted images (500/15).
MR signal intensity of intracranial component (arrow in A, C, and E) for JFM is higher than that of the extracranial component (arrow in B, D, and F) on T1-, T2-, and postcontrast T1-weighted images.
- Fig 3.
Microscopic specimens from left JFM obtained in a 48-year-old woman (patient 7, same patient as Figure 2; hematoxylin-eosin; original magnification × 20).
A, Histologic examination of intracranial component of JFM shows densely packed tumor cells with sparse interstitial collagen bundles.
B, Histologic examination of extracranial component shows isolated tumor cells surrounded by matrix rich in collagen fibers.

** “hyperintense” denotes that signal intensity of the intracranial component of JFM is higher than that of the extracranial component.
*** “isointense” denotes that the signal intensity of the intracranial component of JFM is equal to that of the extracranial component.
**** N/A denotes not applicable.
