Aneurysmal bone cyst (ABC) is a non-neoplastic expansile bone lesion that is common in the long bones; only 2% occurs in the head and neck. We present a case of ABC in a 23-year-old male and describe the clinical and radiological features, histopathology and treatment. Magnetic resonance imaging (MRI) demonstrated multiple internal septations, cysts with fluid-fluid levels of varying intensity, and an intact rim of low-intensity signal completely surrounding the lesion. The tumor was removed by enucleation with resection of the lateral nasal cavity. Histopathologic diagnosis was ABC and fibrous dysplasia. We suggest that MRI is very useful for the diagnosis of ABC. ABC is thought to follow other lesions, and thus when treating ABC, it is important to determine whether any pre-existing lesion has preceded or not; in particular, if the lesion site is in the head and neck region.
动脉瘤样骨囊肿（ABC）是一种非肿瘤性、膨胀性骨病变，常见于长骨；仅2%发生于头颈部。我们报告1例23岁男性的ABC病例，并描述其临床、放射学特征、组织病理学及治疗情况。磁共振成像（MRI）显示多个内部间隔、具有不同强度液-液平面的囊肿，以及完全包绕病变的完整低信号边缘。通过摘除肿瘤并切除外侧鼻腔进行治疗。组织病理学诊断为ABC和骨纤维发育不良。我们认为MRI对ABC的诊断非常有用。ABC被认为继发于其他病变，因此在治疗ABC时，确定是否有任何先前存在的病变很重要；特别是当病变部位位于头颈部区域时。
