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.
