Vascular anomalies in the form of dural arteriovenous fistulas (DAVFs), arteriovenous malformations, and aneurysms are well described in the literature. Pial arteriovenous fistulas (PAVFs) are described to a lesser extent in the literature. When these anomalies are combined, diagnosis and treatment become complex. ⋯ The exact mechanism of PAVF/DAVF formation is unknown. Hemorrhage predilection of PAVF/DAVF is more difficult to predict than a sole fistula, likely secondary to the complex flow dynamics. To our knowledge, this literature review is the largest review to date regarding PAVFs in adult patients and can provide insight into decision making when evaluating treatment options.

Review Case Reports
Predictors of outcomes in fourth ventricular epidermoid cysts: A case report and a review of literature.
To present an illustrative case of fourth ventricular epidermoid cyst and review the literature to identify predictors of surgical outcomes. ⋯ Our review found that in patients with fourth ventricular epidermoid cysts, unfavorable outcomes were predicted by older age and by longer intervals from symptom onset to diagnosis. Clinicians should maintain a high index of suspicion for fourth ventricular epidermoid cysts in patients presenting with cerebellar signs and visual disturbances.

Intracranial aneurysm in patients with sickle cell disease is rare, but with an increased incidence in the recent years. This type of intracranial aneurysm possesses distinctive characteristics, and it has been the subject of case reports and series. ⋯ Intracranial aneurysms related to sickle cell disease mainly affected patients in their 20s, with a contradictory sex ratio in children and adults. Aneurysms manifested predisposition for multiplicity and posterior circulation. There was no difference between children and adults regarding shape and location of aneurysms. However, children with lower aneurysm rupturing rates had better outcomes than their adult counterparts did.

Essential tremor (ET) is the most common movement disorder of adults, affecting an estimated 7 million Americans. Symptoms of ET range from slightly noticeable to debilitating, with 1 cohort study finding 15% of patients were forced into early retirement. Additionally, depression has also been correlated with the severity of disability of ET. Treatment options include propranolol and primidone. Current treatment options are not very effective, with more than half (56.3%) of patients discontinuing medications because of no changes in symptoms. ⋯ With a better side-effect profile and success in a physiologically related condition, we propose more clinical trials and research be carried out on intrathecal baclofen as a potential treatment option, especially drug refractory ET, so as to increase the quality of life of this patient population.
