Review Case Reports
Congenital glioblastoma with distinct clinical and molecular characteristics: case reports and a literature review.
The molecular diagnosis of brain tumors is important in classifying tumors and determining appropriate treatment. Congenital glioblastoma multiforme (GBM) is a rare tumor that occurs in infants, and the prognosis is poor. Approximately 60 patients diagnosed with congenital GBM have been reported. However, few reports have conducted molecular analyses of congenital GBM. ⋯ Congenital GBM demonstrates clinical and molecular characteristics that are different from those of pediatric or adult GBM.

In the setting of trauma, the cause of intracranial hemorrhage (ICH) is frequently attributed to the physical, traumatic event. Caution should still be directed toward nontraumatic (or spontaneous) causes responsible for the trauma, such as hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformation, and hemorrhagic infarcts. The role for immediate computed tomography angiography remains controversial to evaluate for nontraumatic causes. ⋯ ICH in patients with traumatic brain injury seems to be vastly associated with the traumatic event. Only rare cases have been attributed to aneurysmal rupture. None has been associated with arteriovenous malformation. Nevertheless, clinical vigilance remains reasonable, especially in younger patients and those with hemorrhage within the subarachnoid cisterns or sylvian fissure.

For many years, the microsurgical transoral approach has been accepted as the gold standard for anterior decompressions of the craniovertebral junction (CVJ). The introduction of the endoscopic endonasal approach (EEA) has gained wide recognition and overwhelming support in recent years, including for diseases of the CVJ. The aim of this study was to critically analyze and discuss all cases of CVJ diseases approached by means of an EEA so far reported in the literature, including our institutional experience consisting of 6 consecutive patients. ⋯ On the basis of the reviewed literature and our personal experience, the reported increased safety of the EEA needs to be reassessed and discussed.

Review Case Reports
Balloon Angioplasty for in-stent restenosis resulting in carotid stent fracture with literature review of stent-in-stent technique as a viable therapeutic option.
Carotid stent fractures are rare, and multiple etiologies have been proposed to explain their occurrence. We describe a patient with an internal carotid artery (ICA) stent who developed in-stent restenosis. We performed balloon angioplasty to address in-stent restenosis, but he developed a carotid stent fracture after the procedure. To our knowledge, balloon angioplasty has not been reported to cause stent fractures. ⋯ Balloon angioplasty to address in-stent restenosis can secondarily cause stent fractures. We provide evidence of successful management of stent fracture with recurrent in-stent stenosis by repeat stent placement via a stent-in-stent technique.
