Extraneural (EN) metastases and leptomeningeal (LM) metastases from certain primary central nervous system (CNS) tumors, such as pinealoblastomas, are not very common and mostly detected on autopsy. Clinical detection of this entity is, however, very rare and can be attributed to increasing overall survival or probably increased use of surveillance imaging in patients with brain tumors. We demonstrate through this case the potential adjunctive role of positron emission tomography/computed tomography in the identification of asymptomatic LM/EN metastases in high-risk primary CNS tumors.
某些原发性中枢神经系统（CNS）肿瘤，如松果体母细胞瘤的神经外（EN）转移和软脑膜（LM）转移并不常见，大多在尸检时发现。然而，该实体的临床检测非常罕见，这可能归因于总体生存率的提高或脑肿瘤患者监测成像使用的增加。我们通过这个病例证明了正电子发射断层扫描/计算机断层扫描在识别高危原发性中枢神经系统肿瘤无症状LM/EN转移方面的潜在辅助作用。
