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.
Highlights
SFT is an uncommon neoplasm and has been reported with increasing frequency in various anatomic sites, including the central nervous system.[1,2,3,4,5,6,7] We present an SFT arising along the fifth cranial nerve
Contrast-enhanced CT demonstrated a large dumbbell-shaped mass extending from the left middle temporal fossa into the infratemporal fossa via an enlarged foramen ovale
The further development of electron microscopy and immunohistochemistry clarified that this tumor was not from mesothelial but rather from mesenchymal origin, and it is referred to as a SFT, different from a mesothelial tumor
Summary
SFT is an uncommon neoplasm and has been reported with increasing frequency in various anatomic sites, including the central nervous system.[1,2,3,4,5,6,7] We present an SFT arising along the fifth cranial nerve. Contrast-enhanced CT demonstrated a large dumbbell-shaped mass extending from the left middle temporal fossa into the infratemporal fossa via an enlarged foramen ovale. The tumor had a well-defined margin and showed heterogeneous enhancement.
