Most meningiomas are classified as World Health Organization (WHO) grade I. Adjuvant radiation therapy (RT) is commonly recommended for subtotal resections with documented progressive regrowth of lesions with venous sinus involvement. We investigated if recurrence of WHO grade I meningiomas was influenced by adjuvant RT. ⋯ Adjuvant RT does not seem to be a pivotal criterion to reduce the recurrence rate in patients with grade I meningioma, even when venous sinuses are involved.

Review Case Reports
'Isolated Intraventricular Chronic Mucormycosis in an Immunocompetent infant; a rare case with review of literature.'
Mucormycosis of the central nervous system is an uncommon infection caused by saprophytic or parasitic fungi of the subphylum Mucormycotina and order Mucorales viz. Rhizopus, Mucor, and Rhizomucor. Isolated, chronic involvement of the central nervous system is a rare occurrence. To the best of our knowledge, isolated chronic ventricular involvement in an infant has not been reported previously. Isolated intracerebral mucormycosis is a disease of the immunocompromised patient, and to date only 6 cases have been reported in immunocompetent patients, including 2 pediatric cases. ⋯ Although mucormycosis is an acute fulminant infection, chronic isolated cerebral cases are known in the immunocompetent patient. Patients also may present with isolated hydrocephalus, and hence fungal infection must be ruled out in all, especially if a shunt is warranted.

Review Case Reports
Spontaneous resolution of syringomyelia with a 16-year serial magnetic resonance imaging follow-up: A case report and literature review.
The natural course of syringomyelia is unpredictable. Only a few cases of adults with spontaneous resolution of syringomyelia associated with Chiari malformation type I (CM-I) have been reported. The timing of surgical intervention for syringomyelia remains controversial. The present report has documented a case with the longest medical history of syringomyelia reported, the associated imaging findings over 16 years, the mild symptom progression after the spontaneous resolution of syringomyelia, and a review of the relevant reported data. The natural history of our patient provides a unique view regarding the factors that might lead to the development and spontaneous resolution of syringomyelia. ⋯ The findings from our patient suggest that the natural course of mild symptomatic CM-I in adult patients will be benign and nonprogressive. Patients will commonly present with very few or mild symptoms, despite the presence of a large syrinx. It would be reasonable to observe patients with similar mild symptoms and syringomyelia. Surgery will be indicated by the type, severity, and duration of symptoms at the first clinical visit. Periodic follow-up examinations are also essential after spontaneous resolution because the pathophysiology of syringomyelia is incompletely understood and recurrence possible.

Despite widespread use of flow diverters, wide-necked large and giant aneurysms are still treated with other techniques as well. A contemporary review of results from different endovascular treatments is timely. ⋯ All current treatments of large and giant wide-necked aneurysms have comparable safety and efficacy with a trend of superiority of efficacy toward flow diverters. Results of future treatment options and devices can be compared with current technology to evaluate feasibility.
