Abstract

Choroid plexus papillomas (CPPs) are typically considered as benign tumors, with a favorable long-term prognosis. Drop metastasis of CPP into the spinal subarachnoid space is rare. We report a 42-year-old woman who presented with headache and back pain 6 years after removal of a posterior fossa CPP. Magnetic resonance imaging revealed mass lesions in the lumbosacral subarachnoid space and recurrent intracranial tumor. The lesions were resected and histologically diagnosed was CPP. We consider that CPP can spread via cerebrospinal fluid pathways and cause spinal drop metastasis. Therefore, it is necessary to evaluate the whole spinal axis and to perform periodic follow-up examinations in patients with CPP.

摘要

脉络丛乳头状瘤(CPPs)通常被认为是良性肿瘤,具有良好的长期预后。CPP向脊髓蛛网膜下腔的播散性转移很少见。我们报告一名42岁女性,她在切除后颅窝CPP 6年后出现头痛和背痛。磁共振成像显示腰骶部蛛网膜下腔有肿块病变和复发性颅内肿瘤。病变被切除,组织学诊断为CPP。我们认为CPP可通过脑脊液途径扩散并导致脊髓播散性转移。因此,对于CPP患者,有必要评估整个脊柱轴并进行定期随访检查。
