背景：不到 1% 的颅内肿瘤位于松果体区。根据 2007 年世界卫生组织中枢神经系统肿瘤分类，松果体区的乳头状肿瘤被认为是四种松果体实质肿瘤之一。多见于中年，文献中17岁以下少见。在本报告中，我们旨在介绍一例同时具有 CT 和 MRI 表现的松果体区乳头状肿瘤病例，并讨论鉴别诊断。

病例报告：18个月前因脑积水行脑室腹腔分流术治疗的17岁女性患者，因恶心、呕吐、感音神经性耳聋、Parinaud综合征而到神经外科就诊1个月。计算机断层扫描 (CT) 和磁共振成像 (MRI) 已被应用。在非增强 CT 上在松果体和后连合处的定位中观察到一个 58x31x38 mm 的肿块，其中包含囊性和轻度高密度软组织成分。MRI 检查显示肿块充满松果体区，包含实性和大的囊性成分，在 T1 加权图像上呈高信号。静脉注射造影剂后，肿块周围强化更多。DW-MRI 显示部分软组织成分存在弥散受限。

Papillary Tumor of the Pineal Region with Parinaud Syndrome: A Case Report

Backround: Less than 1% of all intracranial tumors are in the pineal region. Papillary tumor of the pineal region is considered one of four pineal parenchymal tumors according to the 2007 World Health Organisation classification of central nervous system tumors. It is mostly seen in the middle age and it is rare under the age of 17 in the literature. In this report, we aim to present a case with papillary tumor of the pineal region with both CT and MRI findings, and discuss the differential diagnosis.

Case report: A 17-year-old female patient who underwent a treatment of ventriculoperitoneal shunt due to hydrocephalus 18 months ago applied to the neurosurgery clinic with nausea, vomiting, sensorineural hearing loss and Parinaud syndrome continuing through 1 month. Computed tomography (CT) and magnetic resonance imaging (MRI) have been applied. A 58x31x38 mm mass with cystic and mild hyperdense soft tissue components was observed in the localization of pineal gland and posterior comissure on non-enhanced CT. MRI examination revealed that the mass filled the pineal region, contained solid and large cystic components, and hyperintense on T1-weighted images. After intravenous contrast media injection, the mass enhanced more peripherally. DW-MRI showed that there is a diffusion restriction in some parts of the soft tissue components. The mass was totally resected, and pathology report revealed that it is a papillary tumor of the pineal region.
