Fractures of the hands and feet in child abuse: imaging and pathologic features.

abstract：:This review offers insight into the possible role of vasa vasorum in the development of intracranial vascular disease. Unique structural features of intracranial vessels and nourishment from the surrounding cerebrospinal fluid environment may account for the relative lack of intracranial vasa vasorum early in life. Ho...
