Background. This report describes a case of primary lung carcinoma that initially presented as a pineal region tumor, an extremely rare region for metastasis. Case. A 68-year-old female was found to have headache, vomiting and consciousness disturbance, and a pineal region tumor was discovered on brain CT. Systematic investigations showed an abnormal lung tumor on chest imaging. We performed endoscopic third ventriculostomy and a biopsy in order to make a definitive diagnosis and provide symptomatic treatment. A histological examination revealed the tumor to consist of dysplastic cells with scanty cytoplasm. Based on the findings of immunostaining, we made a final diagnosis of small cell lung carcinoma metastasis presenting as a pineal region tumor. We administered chemotherapy and radiation therapy, with a marked improvement in the pulmonary and intracranial lesions. Conclusions. We herein present an extremely rare case of small cell lung carcinoma metastasis presenting as a pineal region tumor.
