Endometrial Carcinoma with Cerebellar Metastasis: A Case Report and Review of the Literature

Background: Endometrial cancer is the most common malignancy involving the female genital tract in the United States. There is a paucity of reports of brain metastases in this disease, and most of these reports emphasize that this pattern of dissemination is rare. Case: We present a case of a 63-year-old woman who had high-grade endometrial carcinoma treated with surgery and radiotherapy. She had three separate episodes of relapse in the lungs, the first two relapses being treated surgically. Chemotherapy was also administered following surgery for the first relapse. The third pulmonary recurrence was treated with chemotherapy and then consolidated with thoracic radiation. Four years from the date of diagnosis, and a few weeks after completion of thoracic radiotherapy, she had evidence of a solitary cerebellar metastasis. This was treated surgically and followed by whole brain irradiation. She died 6 months after this central nervous system diagnosis with systemic dissemination of her cancer. Conclusion: The existing literature on brain metastases from endometrial cancer is reviewed together with the patterns of spread of endometrial cancer. We call attention to the unusually long course of this patient. Partially successful treatment for metastatic disease may have predisposed eventual development of brain metastases. This occurrence reinforces reports emphasizing their increasing incidence in association with endometrial cancer.
