神經節神經膠瘤是中樞神經系統中少見的腫瘤，較常發生在小孩與年輕人，本篇報告一例六歲女孩在松果體處有一神經節神經膠瘤，造成兩側眼球不能上視與兩側乳房異常增大，電腦斷層注射對比劑後可見－異質性腫瘤在其下方並含有囊性部分，在磁振造影中以T1為主的影像，腫瘤部分顯示出混合性低與中間的訊號強度，而在以T2為主的影像則轉為高訊號強度，在注射Gadolinium-DTPA則呈現異質性的增強訊號。最後以外科切除此腫瘤而病理診斷為一罕見的神經節神經膠瘤。

Ganglioglioma is a rare tumor of the central nervous system, occuring in all age group but most commonly in children and young adult. We reported a 6-year-old girl with pineal ganglioglioma presenting progressive enlargement of both breasts and impairment of bilateral occulomotor function. A contrast CT scan revealed a pineal region tumor with heterogeneous contrast enhancement and cystic component at lower part of the tumor. In MRI, the solid part of the tumor showed mixed low and intermediate signal intensity in T1WI, which turned to high signal intensity in T2WI and terogeneous enhancement, mainly high intensity, after Gadolinium-DTPA injection in T1WI. The tumor was totally removed and pathology proved it a rare pineal ganglioglioma.
