Background:
Primary hepatic leiomyosarcoma (PHL) is a rare malignant tumor and has non-specific clinical manifestations and imaging characteristics, making preoperative diagnosis challenging. Here, we report a case of PHL presenting primarily with fever, with computed tomography imaging showing a thick-walled hepatic lesion with low-density areas, resembling liver abscess.
Case Summary:
The patient was a 34-year-old woman who presented with right upper abdominal pain and fever over 4 days before admission. Based on the patient's medical history, laboratory examinations, and imaging examinations, liver abscess was suspected. Mesenchymal tumor was diagnosed by percutaneous liverbiopsy and partial hepatectomy was performed. Postoperative pathology revealed PHL. The patient is currently undergoing intravenous chemotherapy with the AD regimen and shows no signs of recurrence.
Conclusion:
When there is a thick wall and rich blood supply in the hepatic lesion with a large proportion of uneven low-density areas, PHL should be considered.
