Sixteen children with brain tumors, fifteen of which were located in the posterior cranial fossa, were followed-up postoperatively with NMR. Four recurrences of medulloblastoma and one recurrence of an ependymoma were found. Three children showed signs of known therapeutic sequelae such as hygroma, atrophy and dilatation of the subarachnoid space. Previously unreported, boundary layer lesions were found in 8 children. The etiology of these lesions and their differentiation from tumor recurrence are discussed.
16例患有脑肿瘤的儿童接受了术后核磁共振成像（NMR）随访，其中15例肿瘤位于后颅窝。发现4例髓母细胞瘤复发和1例室管膜瘤复发。3名儿童出现了已知治疗后遗症的迹象，如蛛网膜下腔囊肿、萎缩和扩张。在8名儿童中发现了以前未报道过的边界层病变。讨论了这些病变的病因及其与肿瘤复发的鉴别。
