Background: Intraabdominal metastasis is a rare complication of metastatic breast cancer. Case Report: We report a case of extensive intraabdominal metastasis with neurologic symptoms of the left leg in a patient who was treated for breast cancer 2 years before. Diagnosis of metastasis was based on imaging techniques and confirmed by histology. Treatment options were discussed in an interdisciplinary tumor board and chemotherapy with a combination of vinorelbine and capecitabine was initiated. After 3 cycles, the patient showed clinical partial response with reduced tumor volume. Conclusion: An interdisciplinary approach is vital to tailor the best treatment option for the individual patient.
