Gastrointestinal Schwannomas: CT features with clinicopathologic correlation

Abstract

OBJECTIVE. The objective of this study was to describe the CT features of gastrointestinal schwannomas with clinicopathologic correlation. CONCLUSION. Gastrointestinal schwannomas are uncommon mesenchymal neoplasms that are uniquely different tumors from their soft-tissue and central nervous system counterparts. They are homogeneously attenuating, well-defined, mural masses on CT. The lack of low-attenuation hemorrhage, necrosis, and degeneration within the tumor may help distinguish these tumors from gastrointestinal stromal tumors on CT. © American Roentgen Ray Society.
