We present a case of probable tumor seeding along the needle tract following computer tomography-guided stereotactic biopsy of an anaplastic astrocytoma in a 23 year old male. Six months after the initial biopsy and 3 months following a second stereotactic procedure for cyst aspiration, a second lesion appeared directly along the biopsy trajectory at a distance from the primary tumor. This lesion is presumed to be recurrent tumor and appears to have been spread iatrogenically following the biopsy of the initial tumor and the subsequent cyst aspiration along the same tract.
我们报告了一例23岁男性间变性星形细胞瘤在计算机断层扫描引导下进行立体定向活检后可能沿针道发生肿瘤种植的病例。在初次活检6个月后以及第二次进行囊肿抽吸的立体定向手术后3个月，在距原发肿瘤一定距离处，沿活检轨迹直接出现了第二个病灶。该病灶被推测为复发性肿瘤，似乎是在初次肿瘤活检及随后沿同一针道进行囊肿抽吸后医源性播散所致。
