Thoracolumbar extradural arachnoid cysts: a study of 14 consecutive cases.

abstract：:Myelocystoceles are rare lesions. Rarer still are thoracic myelocystoceles. Two patients with thoracic myelocystoceles are being reported. The first patient presented with swelling in the thoracic region with paraplegia and incontinence. MR with MR myelography revealed the malformation to be a thoracic myelocystocele....

abstract：OBJECTIVE:Distal middle cerebral artery (dMCA) aneurysms are very rare with a reported frequency of 2-6%. Typically, patients with ruptured distal MCA aneurysms have poor clinical outcomes because often there is both a subarachnoid haemorrhage (SAH) and an intracerebral haematoma (ICH). The goals of this study were to ...
