Abstract
We present the case of an infant with medulloblastoma with extensive nodularity, which had been called cerebellar neuroblastoma. MR imaging clearly revealed a nodular enhancement, which appeared as a grape-like lesion. Single photon emission CT revealed markedly high iodine-123 metaiodobenzylguanidine uptake in the enhancing tumor. Iodine-123 metaiodobenzylguanidine single photon emission CT may be useful in the diagnosis of medulloblastoma with extensive nodularity, which has been considered to be a subgroup of medulloblastoma with extensive neuronal differentiation.
摘要
我们报告一例患有广泛结节性髓母细胞瘤的婴儿病例，该肿瘤曾被称为小脑神经母细胞瘤。磁共振成像清晰显示出结节状强化，表现为葡萄样病变。单光子发射计算机断层扫描显示，强化肿瘤部位碘-123间碘苄胍摄取明显增高。碘-123间碘苄胍单光子发射计算机断层扫描可能有助于诊断广泛结节性髓母细胞瘤，该肿瘤被认为是具有广泛神经元分化的髓母细胞瘤的一个亚组。
