It most commonly arises in the extremities and trunk. Primary hepatic MPNST is extremely rare, and most cases are associated with neurofibromatosis type 1 (NF-1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>This study reports a rare case of hepatic MPNST without NF-1 in a 56-year-old female. The patient presented with upper abdominal pain and distention. Serum tumor markers were all within normal ranges. Radiological examination identified a hypovascular hepatic lesion, which was pathologically confirmed as MPNST. Radical tumor resection was performed. The patient has been followed up for approximately 2 years, with no signs of recurrence or metastasis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The clinical manifestation of hepatic MPNST is nonspecific with normal tumor markers. Radiologically, it mainly manifests as a hypovascular tumor, which requires differentiation from hepatocellular carcinoma, intrahepatic cholangiocarcinoma, and hepatic angiosarcoma. With a literature review, our article provides a comprehensive summary of its CEUS and CECT manifestations, thereby supplementing the limited available data on this rare entity.<\/jats:p>\n
