A 54-year-old woman, who had received chemo-radiation therapy for unresectable uterine cervical cancer with a complete response 8 months earlier was found to have a tumor 6cm in diameter in the spleen by an abdominal ultrasonography (US). Abdominal CT scan revealed a low density mass with a relatively homogeneous center. Magnetic resonance imaging scan showed a low intensity mass on both TI and T2 weighted images. Enhanced US revealed a splenic tumor with peripheral enhancement. Positoron emission tomography (PET) with 2-deoxy-2 [₁₈F] fluoro-D-glucose (FDG) revealed a focal area of increased uptake of radioactivity in the splenic area, but there were no other abnormal areas of increased uptake in the whole body. We diagnosed this tumor as a solitary metastatic splenic tumor, and performed a splenectomy. The histopathologic findings indicated squamous cell carcinoma, which was compatible with splenic metastasis. Only 7 operated cases of solitary splenic metastasis from uterine cervical cancer have been reported.
