Abstract:
Radiofrequency ablation (RFA), a local ablative modality, is gaining acceptance for the treatment of liver malignancies. Despite a relatively low complication rate, tumor seeding resulting from RFA in hepatocellular carcinoma (HCC) treatment can occur. A 44-year-old woman was diagnosed with HCC. Spiral computed tomography (CT) revealed a 2.3 × 2.0-cm mass in the S5 segment, which was treated with RFA on May, 2005. Follow-up imaging, performed at 6-month intervals after RFA, showed complete tumor necrosis. In October 2009, CT revealed a heterogeneous mass, 5.7 cm in diameter, in the right ovary. Since the lesion was limited to the right ovary without evidence of spread, bilateral salpingo-oophorectomy was performed. Histopathology indicated that the metastatic spread from the HCC to the ovary was positive for hepatocyte-specific antigen on immunohistochemistry. The ovary is a rare site for HCC metastasis. Moreover, needle tract implantation of HCC in the ovary is very rare.
