Multiple intraventricular brain metastasis in a case of non-small cell lung carcinoma

Abstract

Intraventricular metastasis is a rare entity encountered in very few malignancies. Although the renal cell carcinoma is the most common primary causing this rare event, due to overall more incidences of lung carcinomas, the intraventricular metastasis by lung cancer is the most common cause. Our patient was a diagnosed case of non-small cell carcinoma and non-small cell lung cancer. (NSCLC) with an advanced stage of disease at the time of presentation that resulted in a poor prognosis. The most common metastatic site in non-small cell carcinoma is bone, followed by the lungs, brain, liver, and adrenal glands. The treatment for metastatic NSCLC consists of systemic therapy using cytotoxic and molecularly-targeted agents and palliative radiotherapy for symptomatic metastases. Surgical resection or gamma knife can be considered for those with isolated brain metastasis for better prognosis.
