Abstract
BACKGROUND: Though endometrial carcinomas are a relatively common cancer of the female genitourinary tract, they rarely metastasize. Similarly, clival metastases make up a tiny fraction of all brain metastases. To the authors' knowledge, an endometrial carcinoma clival metastasis has never been described in the literature; therefore, the authors present the following unusual case of a 69-year-old female with a history of an initially grade 2 endometrial adenocarcinoma that metastasized to her clivus. OBSERVATIONS: Endometrial carcinoma has the potential to metastasize to the clivus. LESSONS: Endometrial carcinoma, even when initially low grade, can metastasize intracranially. Prompt diagnosis with tissue biopsy and radiation is the mainstay of treatment, although the prognosis remains poor. https://thejns.org/doi/10.3171/CASE24392.
