A patient with type 1 neurofibromatosis was followed up with neuroimaging over a period of 12 years. A spontaneous decrease in the size of a histologically verified pilocytic astrocytoma was documented on serial CT and MR examinations. Subsequent studies showed the development of a lesion in the contralateral hemisphere with mass effect and contrast enhancement. Results of a biopsy disclosed normal brain tissue; follow-up imaging showed a spontaneous decrease in the size of this abnormality.
一名1型神经纤维瘤病患者接受了为期12年的神经影像学随访。经组织学证实的毛细胞型星形细胞瘤的大小在系列CT和MR检查中出现自发缩小。随后的研究显示对侧半球出现一个有占位效应和强化的病变。活检结果显示为正常脑组织;随访影像学显示该异常大小自发缩小。
