摘要一位十四岁的男孩因轻微的头部受伤而在两侧颞顶区出现骨膜下血肿。磁共振（MR）成像显示，其中一个血肿已经超出缝合线，并蔓延到颞肌层下。进行性扩大的脑血肿发生，尽管药物和针吸治疗。手术发现血肿使骨膜与颅骨表面分离，骨膜失去了与缝合线的紧密连接。持续吸引引流减少了血肿的大小，无并发症。磁共振成像可以识别骨膜下脑血肿。血肿与颞肌的关系可能是诊断颅内血肿的关键。我们认为，一些青少年脑血肿可能是一个不同的临床实体发生在新生儿。
A 14-year-old boy presented with subperiosteal cephalhematomas in bilateral parietotemporal sites after a minor head injury. Magnetic resonance (MR) imaging showed that one of the hematomas had progressed beyond suture lines, and spread under the temporal muscle layer. Progressive enlargement of the cephalhematomas occurred despite medical and needle aspiration treatment. Surgery found that the hematoma had separated the periosteum from the skull bone surface, and the periosteum had lost the tight attachment to the suture lines. Continuous suction-drainage reduced the size of the hematomas without complications. MR imaging can identify subperiosteal cephalhematomas. The relationship of the hematoma and the temporal muscle may be the key MR imaging finding for the diagnosis of cephalhematoma. We suggest that some juvenile cephalhematomas may be a different clinical entity from those occurring in neonates.
