Abstract

Background: The "split fat sign" is a magnetic resonance imaging (MRI) feature characterized by a thin rim of fat surrounding a soft-tissue mass, best appreciated on T1-weighted images. It is typically associated with well-circumscribed, slow-growing lesions and is most commonly seen in benign peripheral nerve sheath tumors. The aim is to describe the magnetic resonance imaging findings of benign neurogenic tumors and discuss the differential diagnosis with other soft-tissue...
