Treatment outcomes of incidental intracranial meningiomas: Results from the IMPACT cohort.
Incidental findings such as meningioma are becoming increasingly prevalent. There is no consensus on the optimal management of these patients. The aim of this study was to examine the outcomes of patients diagnosed with an incidental meningioma who were treated with surgery or radiotherapy. ⋯ The morbidity after treatment of incidental intracranial meningioma is not negligible. Considering most operated tumors are WHO grade 1, treatment should be reserved for those manifesting symptoms or demonstrating substantial growth on radiologic surveillance.

Cervical pial arteriovenous malformation (AVM) is an extremely rare condition that can present with progressive myelopathy or acute hemorrhage (subarachnoid or intramedullary). The classification process is still a topic of discussion, given the limited number of cases described, as well as correct therapeutic management. Here, we present a case of a young female with anterior cervical pial AVM associated with spinal aneurysm. ⋯ Surgical procedure with perioperative neuromonitoring is an effective way to treat anterior cervical pial AVM associated with spinal aneurysm. A multidisciplinary approach is always suggested.

Intracranial aneurysms in Caucasian patients with Moyamoya Disease: A U.S. single center case series and review.
Intracranial aneurysms (IA) are associated with moyamoya disease (MMD). There are no clinically tested treatment guidelines. Reporting of cases is vital to better understand the underlying pathophysiology and potential ethnic predispositions and improve patient selection for intervention. ⋯ Revascularization surgery seems to be an effective method of indirectly treating IA in patients with MMD. Previous literature in addition to our series shows that endovascular embolization is safe and efficacious in treating IA of most locations in patients with MMD. The use of open microsurgery for direct aneurysm treatment in this population poses many challenges.

Multifocal Intracranial Ganglioglioma in a Sexagenarian: A Case Report and Review of the Current Literature.
Gangliogliomas are rare, well-differentiated, low-grade neoplasms that most often occur unifocally in children and most commonly affect the temporal lobe. Gangliogliomas that occur in patients age >40 years tend to have worse prognoses. These tumors generally stain positively for neural and glial cell markers, as well as CD34. Here we report an unprecedented case of multifocal intracranial ganglioglioma in an adult age >40 who had a favorable course, and review the current literature on multifocal intracranial gangliogliomas. ⋯ Multifocal intracranial gangliogliomas are exceedingly rare tumors, especially in adults. These tumors present unique management barriers because as they are multifocal at the time of diagnosis, making resection more technically challenging. In our review, the average age at diagnosis was 19.2 years, and 80% of the cases had at least 1 lesion in the temporal lobe. Two studies opted for resection of intracranial tumors, whereas the remaining studies performed biopsy with conservative management and serial imaging. Biopsy was performed in all cases. We present the first case of an intracranial multifocal ganglioglioma in a patient age >40 years with lesions in the occipital lobe, corpus callosum, and frontal lobe at presentation.

Review Case Reports
Recurrent spinal intramedullary arachnoid cyst: A case report and literature review.
Symptomatic intramedullary arachnoid cysts are rarely observed lesions, particularly in the pediatric age group. Treatment includes cyst fenestration or resection of the cyst wall, and recurrence after surgery has never been reported. We report a rare case of a spinal intramedullary arachnoid cyst, which recurred after cyst fenestration and required reoperation after a certain period. ⋯ To the best of our knowledge, this is the first report of recurrence of an intramedullary arachnoid cyst. This case indicates the importance of considering the resection of cyst wall as possible because of the probability of cyst recurrence after fenestration, while careful observation is the option in the short term, especially for children or high-risk cases.
