Case ReportsEndovascular treatment of blood blister-like aneurysms of the internal carotid artery.
Because of its thin wall, an aneurysm arising from the posterior wall of the internal carotid artery (ICA), the so-called blood blister-like aneurysm (BBA), is difficult to manage surgically and is often associated with high morbidity and mortality rates. The authors treated these aneurysms endovascularly. In this paper, they present angiographic and clinical results obtained in patients with ICA BBAs treated endovascularly. ⋯ All ICA BBAs that were treated by endosaccular coil embolization exhibited regrowth of the aneurysm. Some of the lesions rebled. The majority of patients who underwent ICA trapping experienced excellent outcomes. Based on the authors' experiences, they suggest that ICA trapping including the lesion segment should be considered as a first option for definitive treatment if a BOT reveals satisfactory results. Regarding trapping methods, endovascular treatment may be preferred because of its convenience and safety.

Surgical and endovascular management of symptomatic posterior circulation fusiform aneurysms.
Patients with fusiform aneurysms can present with subarachnoid hemorrhage (SAH), mass effect, ischemia, or unrelated symptoms. The absence of an aneurysm neck impedes the direct application of a clip and endovascular coil deployment. To evaluate the effects of their treatments, the authors retrospectively analyzed a consecutive series of patients with posterior circulation fusiform aneurysms treated at Stanford University Medical Center between 1991 and 2005. ⋯ Certain posterior circulation aneurysm locations (PCA, VA-PICA, and BA-VBJ) represent separate disease entities affecting patients at different ages with distinct patterns of presentation, treatment options, and outcomes. Favorable overall long-term outcome can be achieved in 90% of patients with PCA aneurysms, in 60% of those with VA-PICA aneurysms, and in 39% of those with BA-VBJ aneurysms when using endovascular and surgical techniques. The natural history of the disease was poor in patients with incomplete aneurysm thrombosis after treatment.

Stereotactic radiation treatment for recurrent nonbenign meningiomas.
The authors analyzed the results of stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT) for the treatment of recurrent meningiomas that were described at initial resection as showing aggressive, atypical, or malignant features (nonbenign). ⋯ Stereotactic radiation treatment provided effective local control of "aggressive" Grade I and Grade II meningiomas, whereas Grade III lesions were associated with poor outcome. The outcome of cases in the malignant progression group was intermediate between that of the Grade II and Grade III groups, with the lesions showing a tendency toward malignancy.

Cargo areas of pickup trucks: an avoidable mechanism for neurological injuries in children.
Falls from pickup truck cargo areas represent a unique mode of injury in children and adolescents. The goal of this study was to identify the neurological spectrum of injuries resulting from children riding in the back of pickup trucks. ⋯ Falls or ejections from pickup truck cargo areas result in a relatively high incidence of traumatic head, spine, and peripheral nerve injury. Head CT scanning should therefore be considered in pediatric patients with this mechanism of injury. Cargo area occupancy poses an unacceptable risk of injury and should be avoided.

Case ReportsThoracic lipomeningocele associated with diastematomyelia, tethered spinal cord, and hydrocephalus. Case report.
Accessory human tails are uncommon malformations consisting of meningeal and neural structures and possibly occult spinal dysraphism (pseudotails). The thoracic location of a lipomeningocele constituting a pseudotail is very rare. ⋯ The preoperative moderate ventricular dilation was decompressed by the surgical repair of the spinal malformation and required a specific treatment. The authors discuss the rare association of these clinical entities and conclude that complete spine and brain neuroimaging studies are necessary for the correct surgical planning of this kind of malformation.
