Contrast‐Enhanced Ultrasound Findings in Primary Hepatic Leiomyosarcoma: A Case Misdiagnosed as Liver Abscess

Primary hepatic leiomyosarcoma (PHLS) is a rare malignant tumor of mesenchymal origin in the liver, with nonspecific clinical manifestations. High fever as the initial symptom is uncommon, making it easily misdiagnosed as a liver abscess. In this case, the tumor was initially mistaken for a liver abscess. Contrast-enhanced ultrasound (CEUS) corrected the diagnosis and helped avoid inappropriate treatment.
