Abstract
|
|
|
Pineal parenchymal tumor of intermediate differentiation(PPTID) in adult is rare disease, but is capable of cerebrospinal
fluid dissemination, similar to pineoblastoma. We present a case of a female patient aged 35 presented with 3-month
history of paraparesis and urinary incontinence. Magnetic resonance imaging(MRI) demonstrated multiple vertebral and
cerebral metastases originating from pineocytoma on which surgery and postoperative radiotherapy had been performed 7
years earlier, respectively. The patients received radiotherapy on the whole spine and whole brain, and adjuvant chemotherapy.
In patients with PPTID, long term attention to leptomeningeal dissemination is required even if the tumor has
been removed totally.
