Early brain metastases in endometrial carcinoma.
Endometrial carcinoma is the most common invasive neoplasm of the female genital tract. Yet, intracranial metastases are rare and usually associated with widespread disease. We report three patients with endometrial carcinoma and early brain metastases, two with unsuspected endometrial carcinoma presenting with neurologic symptoms and one who developed neurologic symptoms on the day of hysterectomy. Histologically, one tumor was a clear cell carcinoma and two were endometrial adenocarcinoma. In tumors with a mixture of nuclear grades, the most undifferentiated portion metastasized. Two tumors displayed vascular invasion and deep myometrial invasion. Only one had positive estrogen receptors. Intracranial metastases can occur early in the course of endometrial carcinoma. They are associated with aggressive high-grade neoplasms with deep myometrial and vascular invasion.
