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.
