Introduction: The FOLFOX6 scheme is a combination drug chemotherapy that contains calcium leucovorin (folinic acid), fluorouracil, and oxaliplatin, the chronic use of chemotherapy with oxaliplatin can progress to focal nodular hyperplasia (FNH), which is a benign hepatic lesion.
Case Report: We present a case of a 26- year-old female diagnosed with an ovarian mixed germ cell tumor with extension to the peritoneum, treated with 12 cycles in 9 months with neoadjuvant chemotherapy FOLFOX 6 scheme and oophorectomy. A three-year follow-up CT showed three nodular and hypervascular hepatic lesions suspicious of metastatic disease; an MRI with liver-specific contrast confirmed the diagnosis of FNH.
