Our case report describes a primary aneurysmal bone cyst (ABC) of the maxillary sinus in a 12-year-old girl. The young patient presented with progressive diplopia, strabismus, and rapidly growing painless swelling of the left cheek. Imaging studies showed a heterogeneous contrast enhancing mass expanding the left maxillary sinus. The lesion was completely resected endoscopically and histological examination reported it as an ABC. The patient recovered well and is free of recurrence 9 months following surgery. ABC is a benign lesion usually associated with other bone pathology (fibrous dysplasia). It may behave aggressively and invade the orbit; so resection is necessary. Minimally invasive techniques such as endoscopic sinus surgery can be performed successfully in select cases. Long follow up is important because recurrence may occur, in which case further resection is warranted.
我们的病例报告描述了一名12岁女孩上颌窦原发性动脉瘤样骨囊肿（ABC）。这位年轻患者出现进行性复视、斜视以及左侧脸颊迅速生长的无痛性肿胀。影像学检查显示一个不均匀强化的肿块，使左侧上颌窦扩大。病变通过内镜完全切除，组织学检查报告为ABC。患者恢复良好，术后9个月无复发。ABC是一种通常与其他骨病变（骨纤维发育不良）相关的良性病变。它可能具有侵袭性并侵犯眼眶；因此有必要进行切除。在某些病例中，可以成功地采用诸如鼻内镜鼻窦手术等微创技术。长期随访很重要，因为可能会复发，在这种情况下需要进一步切除。
