Abstract

Abstract Background Multiple-organ primary tumors can invade the ovary through lymphatic and hematogenous routes, presenting as ovarian Krukenberg tumors, but these rarely originate from the gallbladder. Krukenberg tumors can present similar to primary ovarian tumors; however, their treatments are completely different. Patient concerns A 62-year-old Chinese woman presented with abdominal distension for six months and weight loss of five kilograms for two months. Diagnoses Based on multiple imaging examinations, the patient was preliminarily diagnosed with a malignant tumor of unknown origin with multiple metastases (omentum). To identify the origin of the malignancy, the patient underwent real-time contrast-enhanced ultrasound-guided percutaneous biopsy. The results revealed a perihepatic hypoechoic lesion and right adnexal mass that were both metastatic adenocarcinomas from the gallbladder. Interventions The patient initially received chemotherapy with gemcitabine and cisplatin instead of surgery. However, the tumor increased in size on re-examination after two cycles, so the treatment was shifted to a combination regimen with durvalumab for six cycles. Outcomes The treatment proceeded smoothly, with no recurrence or obvious progression of the cancer during follow-up. Conclusions Differentiating between primary and metastatic ovarian tumors is important. Early diagnosis and effective treatment options are essential for patient survival. CEUS-guided percutaneous biopsy is a valuable procedure for patients with multiple metastases who cannot tolerate surgery.
