Abstract

A 30-year-old woman four years ago underwent left mastectomy due to stage I invasive breast carcinoma with 8mm sized invasive mass, histologic grade 2/3, nuclear grade 2/3 and lymphovascular invasion. She had radiation therapy only without any chemotherapy or hormone therapy. F-18 FDG PET/CT scan underwent for evaluation of recurrent lesion. PET/CT showed multiple peritoneal carcinomatoses in the right / lateral abdomen/right pelvic cavity and in the perihepatic space, large hepatic metastasis in the right lobe of the liver, osteolytic bone metastasis in the right iliac bone, multiple node metastases in the left paraaortic node, left common iliac node and both internal iliac nodes. Large amount of ascites is noted in pelvis and lower abdominal cavity on the abdominal –pelvic CT. Ascite cytology was performed to rule out another malignant lesion due to unusual metastatic findings. Cytology showed positive for malignant cells consistent with metastatic carcinoma from previous breast carcinoma. Immunohistochemical staings with breast cancer and ascites were entirely equivalent.
