An unusual case of aggressive endometrial adenocarcinoma metastasis to the clivus: illustrative case.

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.
