Aneurysmal bone cyst of the skull is rarely seen. There are 29 reported cases in the literatures as far as we could collect. We reported an additional case of aneurysmal bone cyst of the skull which originated from the right parietal bone of 4-year-old boy. We have summarized these 29 cases. The age incidence in this series is from 14 month-old to 31 year-old. There are 11 cases under the age of 10. In most cases clinical symptoms are palpable mass or headache and exophthalmos. Eyeball displacement and proptosis are also the symptoms when this disease occurs at the orbital roof. According to the characteristic radiographic appearance, it is "blown-out pattern with a shell of periosteal new bone over the mass or soap-bubble appearance". However in our case the radiological finding was osteolytic. It is possible to remove totally when this lesion occurs in the cranial vault, but only curettage may be performed when the skull base is involved. Total removal is the best treatment. Radiation therapy is usually done in the recurrent cases. It is necessary to follow up for at least 4 years because of the rarity of recurrence beyond 4 years after the initial treatment. We also described the other differential diseases and pathogenesis of this disease.
颅骨动脉瘤样骨囊肿罕见。据我们所能收集到的文献报道，仅有29例。我们报告了另外1例起源于一名4岁男孩右顶骨的颅骨动脉瘤样骨囊肿病例。我们总结了这29例病例。该系列病例的年龄范围从14个月至31岁。10岁以下的有11例。大多数情况下，临床症状为可触及的肿块、头痛和眼球突出。当该病发生于眶顶时，眼球移位和眼球突出也是症状。根据典型的影像学表现，其为“肿块上有一层骨膜新生骨的吹气球样表现或肥皂泡样表现”。然而，我们病例的影像学表现为溶骨性。当该病变发生于颅顶时有可能完全切除，但当累及颅底时可能仅行刮除术。完全切除是最佳治疗方法。复发病例通常进行放射治疗。由于初始治疗后4年以上复发罕见，因此有必要至少随访4年。我们还描述了该疾病的其他鉴别诊断疾病和发病机制。
