Imaging features in combined atlantoaxial and occipitoatlantal rotatory subluxation: a rare entity. Case report.

abstract：OBJECT:Noninvasive neuroimaging techniques are increasingly identifying unruptured intracranial arterial dissections (IADs) at examination for headache or ischemic symptoms. Approximately 3% of cases of aneurysmal subarachnoid hemorrhage (SAH) are caused by IADs in Japan, but the natural history of unruptured IADs is n...
