Small cell lung carcinoma (SCLC) represents 15-20% of all lung cancers. It is characterised by rapid growth and early metastatic dissemination. Generally, the prognosis of these patients is poor. When brain metastases develop, the prognosis is even poorer. Most of these cases present parenchymal metastases; however, intraventricular dissemination may also occur although it is very uncommon. To our knowledge the case reported here is the first showing multiple synchronic intraventricular dissemination from SCLC.
小细胞肺癌（SCLC）占所有肺癌的15%-20%。其特点是生长迅速且早期发生转移扩散。一般来说，这些患者的预后较差。当发生脑转移时，预后更差。这些病例大多表现为实质转移；然而，尽管非常罕见，但也可能发生脑室内播散。据我们所知，本文报道的病例是首例显示小细胞肺癌发生多处同步脑室内播散的病例。
