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.
MANAGEMENT AND OUTCOME: The patient continued her follow-up without other treatment and metastatic disease.
DISCUSSION: While most multiple liver lesions in a patient with cancer will be suspicious of metastasis, a careful drug history should be obtained, as an oxaliplatin-related side effect to develop FNH has been reported. MRI with liver-specific contrast has a positive predictive value of 95% because of the biliary excretion through OATP1B3 transporter, expressed in functional hepatocytes and overexpressed in some liver tumors such as FNH, so it should be performed when FNH is suspected.
