Benign peripheral nerve sheath tumors (BPNSTs) are relatively common benign tumors, accounting for 10-12% of benign soft tissue tumors in the general population.
Benign peripheral nerve sheath tumors (BPNSTs) are relatively common benign tumors, accounting for 10-12% of benign soft tissue tumors in the general population.
Magnetic resonance imaging (MRI) plays a central role in the characterization and monitoring of soft tissue tumors.
Recently, a study published in the journal European Radiology evaluated the potential of conventional MRI and diffusion-weighted imaging (DWI) to differentiate between benign and malignant peripheral nerve sheath tumors (PNSTs), and accurate characterization of PNSTs through non-invasive imaging techniques to avoid inconvenience.
This study retrospectively analyzed 87 patients with malignant or benign PNSTs on the trunk or limbs confirmed by pathology from September 2014 to December 2017.
This study retrospectively analyzed 87 patients with malignant or benign PNSTs on the trunk or limbs confirmed by pathology from September 2014 to December 2017.
A total of 55 cases of indeterminate tumors included 18 malignant PNSTs and 37 benign PNSTs.
