Small cell lung cancer metastasis in the pituitary gland presenting with seizures and headache.

We report an adult female with a small cell lung cancer (SCLC) pituitary metastasis who presented with seizures and headache. While headache is a common presentation of pituitary metastases, seizures have been very rarely reported. The patient was found on MRI to have a suprasellar tumor with pituitary infundibulum involvement. She underwent endoscopic transsphenoidal resection of the tumor which was shown to be metastatic SCLC. Subsequent imaging revealed widespread systemic metastases. The patient subsequently underwent chemotherapy.
