广泛结节化的髓母细胞瘤是最常见的儿童恶性脑肿瘤的一种罕见亚型，并且与更有利的预后相关。作者报告了一例10个月大的女孩，患有后颅窝肿瘤，在扩散加权磁共振成像序列上结节过多，扩散率降低，葡萄样钆后造影剂增强特征明显。其独特的神经放射线摄影特徴经组织病理学证实，并被诊断为髓母细胞瘤合并广泛结节。这个病例强调了术前识别这种独特的髓母细胞瘤亚型的重要性，因为更有利的结局可能会排除不太积极的医疗管理。
Medulloblastoma with extensive nodularity is a rare subtype of the most common malignant childhood brain tumor and has been associated with more favorable prognosis. The authors report the case of a 10-month-old girl with a posterior fossa tumor of excessive nodularity with decreased diffusivity on diffusion-weighted magnetic resonance imaging sequences and robust grape-like postgadolinium contrast enhancing features. The unique neuroradiographic features were confirmed by histopathology and a diagnosis of medulloblastoma with extensive nodularity was made. This case highlights the importance of recognizing this unique medulloblastoma subtype preoperatively, as the more favorable outcome may preclude less aggressive medical management.
