Review Meta Analysis
Systematic Review and Meta-Analysis of Management Strategies and Outcomes in Adult Spinal Neurocysticercosis.
Spinal involvement in neurocysticercosis is rare and can lead to debilitating injury if not diagnosed and treated early. We aim to provide the reader with a thorough analysis of the best available evidence regarding patient characteristics, optimal treatment modality, and outcomes in cases of spinal neurocysticercosis. ⋯ Spinal involvement in neurocysticercosis should be considered in patients from or who traveled to endemic areas presenting with ring-enhancing lesions. Combined treatment with surgery followed by cysticidal and steroid medication seems to be superior to surgery or medical treatment in isolation and seems to provide the highest chances of recovery.

Dilatation of Virchow-Robin spaces (dVRS) have been described in the development of hydrocephalic syndromes. We report an unusual case of a type III dVRS presenting as a mimic of normal pressure hydrocephalus (NPH), due to distortion at the level of the cerebral aqueduct. ⋯ This is an illustrative case of a subacute obstructive hydrocephalus due to a collection of periaqueductal dVRS, leading to an insidious clinical presentation mimicking NPH. We reviewed the literature for key clinical presentations and describe neuroanatomical considerations as well as primary treatment strategies. Various hydrocephalic syndromes may present with classic symptoms from Hakim's triad; such symptoms are not specific to idiopathic NPH. Both endoscopic third ventriculostomy and shunting may be efficacious. In our case, dVRS may serve as both a cause of and compensatory mechanism in a subacute obstructive hydrocephalus of unknown etiology. Our case highlights the need to understand the neuroanatomy of aberrant cerebrospinal fluid spaces in hydrocephalic syndromes. Further studies of dVRS would provide valuable insights into the pathogenesis of hydrocephalus.

Vasospasm, delayed ischemic neurologic deficit (DIND), and ischemic brain lesions after acute subarachnoid hemorrhage (SAH) are associated with increased morbidity and mortality. The purpose of this study was to analyze age cutoffs for vasospasm, DIND, and ischemic brain lesions after SAH. ⋯ Higher incidences of any vasospasms, severe vasospasms, DIND, and ischemic brain lesions were observed in younger SAH patients.

Review Meta Analysis
Association between aspirin use and risk of aneurysmal subarachnoid hemorrhage: a meta-analysis.
To assess the association between aspirin use and risk of aneurysmal subarachnoid hemorrhage (aSAH). ⋯ A short-term use of aspirin (<3 months) is associated with an elevated risk of aSAH, whereas the role of its long-term use in either decreasing or increasing the risk of aSAH still requires well-designed, large-scale randomized control trials for verification.

Review Case Reports
Recurring Primary Xanthomatous Hypophysitis Behaving Like Pituitary Adenoma: Additional Case and Literature Review.
Xanthomatous hypophysitis (XH) is the rarest histologic type of primary hypophysitis. It is nonlymphocytic and characterized by an infiltration of the pituitary gland by lipid-laden histiocytes and macrophages. The clinical and radiologic features overlap heavily with pituitary adenomas and are prone to misdiagnosis. We describe a rare case of XH recurrence at 1 year, treated surgically. Moreover, we provide an updated review of the literature to further elucidate useful management and detection strategies. ⋯ XH presents similarly to nonfunctional adenomas and diagnosis remains difficult without surgical pathology, requiring meticulous immunohistochemistry to prevent misdiagnosis. Thus, XH should be considered as a rare cause in the differential of disease of the sellar region. Management can parallel that of pituitary neoplasm, with a focus on radiosurgery, re-resection, and high-dose steroids.
