Review Case Reports
Intracranial DAVF as a reversible cause of dementia: case series and literature review.
Intracranial dural arteriovenous fistulas (DAVFs) can manifest with a reversible form of dementia and parkinsonism that may be related to medullary venous hypertension and impaired cortical venous drainage. We report a consecutive case series of patients with DAVFs who presented with cognitive decline and report angioarchitecture and outcomes of treatment. ⋯ Cognitive decline is a rare but reversible manifestation of DAVFs that have impaired venous drainage of the transmedullary veins and associated medullary venous hypertension.

Review Case Reports
Management of Choroid plexus tumors in infants and young children up to 4 years of age: An institutional experience.
Choroid plexus tumors (CPTs) are rare tumors characterized by papillary and intraventricular growth. The young age of presentation of such tumors, especially in infants, and the lack of consensus on adjuvant therapy in case of atypical choroid plexus papilloma (aCPP) and choroid plexus carcinoma (CPC) create dilemma for the management of such tumors. We discuss the presentation, management, complications, and outcome in 15 patients (children 4 years of age and younger) and review pertinent literature. ⋯ CPTs are challenging tumors in infants and very young children because of the potential for massive blood loss. CPP is associated with lesser blood loss and favorable outcome compared with aCPP and CPC. Massive blood loss in CPC and aCPP can be life threatening as has been shown in our series. CPC has a rapid proliferation potential as shown in one of our cases. Attempts at decreasing vascularization of such tumors should be made by various methods, including preoperative embolization and neoadjuvant chemotherapy; however, a consensus on this is lacking.

Intracranial arterial dissection (IAD) is a rare cerebrovascular disease that is likely underdiagnosed because of the inherent difficulty of visualizing the subtle radiographic signs of the pathologic small intracranial arteries. No widespread consensus exists on the treatment of IAD, and thus it is often managed empirically because of the absence of major randomized controlled trials. In this study, we conducted a systematic review to evaluate the management and treatment options for IAD. ⋯ Given these findings, clinicians should prescribe antiplatelet therapy for patients with IAD presenting with ischemia and consider endovascular treatment for those presenting with hemorrhage. However, further investigation is required given the heterogeneity of methods and reporting outcomes in the investigated studies.

Review Case Reports
Re-recurrence of intracranial aneurysm with proximal vascular stenosis after primary clipping and secondary endovascular embolization: A case report and literature review.
It was known that a small number of patients could have intracranial aneurysm recurrences after either surgical clipping or endovascular embolization treatment. However, early recurrence within 1 month after the treatment and re-recurrence has rarely been reported before. ⋯ Re-recurrence of intracranial aneurysm could happen after initial successful treatment with surgical clipping and endovascular embolization. In addition to the patient's medical history and characteristics of the aneurysm, local vascular stenosis might also contribute to its recurrence. Close postoperative follow-up is required for these patients.

In lumbar degenerative spondylolisthesis (DSL), the criteria and extent of surgical treatment have not been strictly defined owing to the adjacent segment disease theory and unclear molecular pathogenesis. The present study analyzed the clinical and radiographic findings of patients after lower lumbar fusion surgery with single and 2-level DSL and explored the inflammatory mediator's role in DSL evolution and symptoms. ⋯ Our findings did not support the adjacent segment disease theory. However, later development of these changes could not be excluded. The cytokines, chemokines, and growth factors play a significant role in DSL pathogenesis and symptoms.
