Intra- and extracranial solitary fibrous tumor of the trigeminal nerve: CT and MR imaging appearance

K Motoori et al. AJNR Am J Neuroradiol. 2010 Feb.

Abstract

We describe a rare case of SFT existing along the mandibular division of the trigeminal nerve and extending down into the infratemporal fossa through the foramen ovale. The tumor showed heterogeneous hypointensity on T2-weighted images and marked enhancement on CT and MR images.

A, Axial contrast-enhanced CT scan shows an enlarged left foramen ovale (arrows) by the enhanced tumor. B, Axial contrast-enhanced CT scan of the caudal side of A shows the tumor compressing the maxillary bone, left pterygoid plate, and mandible (arrows), without destruction.

Fig 2.
A, Coronal T2-weighted image shows a dumbbell-shaped tumor passing through left foramen ovale (arrows). The tumor is mainly hypointense to white matter. The lateral part of the intracranial component (arrowhead) shows higher intensities than other parts of the tumor. White matter of the left temporal lobe shows high intensities (asterisk). B, Axial T1-weighted image shows isointensity of the tumor to the brain. The tumor has low-intensity foci, suggesting a flow-void condition (arrows). C, On a coronal contrast-enhanced fat-suppressed T1-weighted image, the tumor shows heterogeneous enhancement. The lateral part of the intracranial component shows different strong enhancement (arrowheads).
