Aneurysmal bone cysts (ABCs) are rare blood-filled cystic lesions that are found in the long bones and spine. Here, we present a case of an ABC found in the lateral mass and lamina of C1. Lesions in this area provide a surgical challenge because of its difficulty to access as well as its need for reconstruction. We describe a novel use of intraoperative navigation (ION) to assist in the placement of a C1 lateral mass titanium cage.
An 18-year-old female patient presented with headaches and progressive neck pain. Imaging revealed a large cystic lesion involving the C1 lamina and right lateral mass. The patient underwent ION-assisted aggressive intralesional resection of the ABC and reconstruction of the C1 lateral mass with a static titanium cage, supplemented with posterior fusion from the occiput to C3. At 2-year follow-up, there was no evidence of recurrence and the hardware remained intact.
ION is a useful aid in assessing the extent of tumor resection and performing cage reconstruction of the C1 lateral mass.
骨动脉瘤样囊肿（ABCs）是一种罕见的充满血液的囊性病变，多见于长骨和脊柱。在此，我们报告一例在C1侧块和椎板发现的ABC病例。该区域的病变因其难以暴露以及需要重建，给手术带来了挑战。我们描述了术中导航（ION）的一种新用途，即辅助放置C1侧块钛笼。
一名18岁女性患者出现头痛和进行性颈部疼痛。影像学检查发现一个巨大的囊性病变，累及C1椎板和右侧块。患者接受了ION辅助下对ABC进行的积极病损内切除，并使用静态钛笼对C1侧块进行重建，辅以从枕骨到C3的后路融合术。在2年的随访中，没有复发迹象，植入物保持完好。
ION有助于评估肿瘤切除范围，并有助于进行C1侧块的笼状重建。
