There have yet to be any large-scale studies in China on headaches after traumatic brain injury (TBI). We evaluate the incidence of headache after TBI and investigate risk factors and functional outcome in a large tertiary center with a high caseload. ⋯ We present the findings of the first study on headaches after TBI in China. Headaches were found to occur in most patients with TBI and persisted through the first year after injury. The incidence of posttraumatic headache observed here is comparable with previously published studies outside China.

Tarlov cyst is an abnormal expansion of the spinal nerve sleeve, and it communicates with the subarachnoid cavity via a perineural fistula. This study presents our experience of a balloon-assisted fistula sealing procedure in treating Tarlov cyst. ⋯ The balloon-assisted fistula sealing procedure is safe and effective for Tarlov cyst, especially for the single cyst. It is a good complement to the cyst wall imbricating procedure.

Delta-like ligand 4 (DLL4) and Jagged1 (JAG1), 2 vascular Notch ligands, are involved in the process of tumor angiogenesis. The present study investigates their relationship with microvascularization and the prognostic effect in primary glioblastoma. ⋯ DLL4 and JAG1 may have opposing effects on tumor angiogenesis in glioblastoma. The Notch pathway may be a new target for antiangiogenic therapy in glioblastoma.

The ventriculoscopic approach has been considered to be more safe and effective in the treatment of hydrocephalus, arachnoid cysts and intraventricular lesions in neurosurgery. We found that intraoperative bleeding-related complications have the greatest impact on ventriculoscopic surgery. Until now, few studies fully discussed this complication. ⋯ Intraoperative hemorrhage in ventriculoscopic surgery should be paid more attention. Generally, a skilled neurosurgeon can address hemorrhage with a low complication rate. Consequently, the ventriculoscopic approach is safe and effective in the treatment of specified brain ventricular disease.

Abscess formation within a glioblastoma has been reported rarely. In the few reported cases, after aspiration to treat a presumed abscess, lesions recurred over a short period and, consequently, glioblastoma was recognized. We present a case of a glioblastoma that developed 1.5 years after successful treatment of a brain abscess. A latency of 1.5 years before symptom development seems overly long, even if the glioblastoma was present at the time of the initial brain abscess. Hence, we consider this a possible de novo glioblastoma arising from glial scar tissue. We also discuss possible mechanisms underlying malignant transformation. ⋯ Development of glioblastoma after treatment of a brain abscess is rare; the pathogenesis is open to speculation. Based on the clinical course, the pathologic findings, and comparison with previous reports, de novo glioblastoma arising from glial scar tissue may be the most likely explanation of the current case. If so, to our knowledge, this is the first report of this condition.
