Lateral Hepatic Fissure Peritoneal Carcinomatosis as a Pitfall for Hepatic Metastasis of Advanced Ovarian Cancer.

A 52-year-old woman previously treated for a stage IIIc high-grade ovarian serous carcinoma presented right upper quadrant abdominal pain, 3 years after extended surgery and chemotherapy. Abdominal CT, MRI, and 18F-FDG PET/CT showed a right hepatic mass, consistent for lone recurrence nearby the hepatic lateral fissure. Preoperative and histologic examination identified a peritoneal lateral fissure lesion. The patient underwent atypic segment 5 segmentectomy. She has been disease-free for 3 years now. Advanced ovarian cancer can be responsible for perihepatic sulcus lesions, such as this right fissure lesion. They should not be mistaken for inoperable parenchyma metastases.
