ARTICLE HIGHLIGHTS
Research background

Peripheral nerve sheath tumors (PNSTs) is a rare group of neoplasms in the orbit. Although computed tomography (CT) and magnetic resonance imaging (MRI) features could provide clues for the diagnosis of PNSTs, there are very few studies detailing the features of these tumors identified using imaging technology at present.

Research motivation

The comprehensive characteristics of 34 patients with PNSTs were collected, and we found that imaging played as an important role in the diagnosis of this rare tumor.

Research objectives

This study was designed to compare the clinical, pathological, CT, and MRI data in 34 patients with periorbital sheath tumors, including 21 schwannomas, 12 neurofibromas, and 1 plexiform neurofibroma.

Research methods

All data were analyzed retrospectively in 34 patients with periorbital sheath tumors diagnosed using histopathology from January 2013 to August 2021.

Research results

Schwannomas mostly occur in the intramuscular space with small tumor volume and rare bone involvement. Neurofibromas develop in the extrapyramidal space with larger tumor volume and more bone involvement. One case of plexiform neurofibroma showed tortuous and diffuse growth along the nerve, with a worm-like appearance on imaging.

Research conclusions

Imaging manifestations have great value in the diagnosis of orbital peripheral nerve sheath tumors.

Research perspectives

Further studies will elucidate the imaging characteristics of all types of orbital PNSTs using larger sample sizes, and focus on the value of imaging in the surgery of orbital PNSTs.
