Rhabdoid Meningioma Arising Concurrent in Pulmonary and Intracranial with a Rare Malignant Clinical Progression: Case Report and Literature Review.
Rhabdoid meningioma (RM) is an unusual variant of meningioma, classified as World Health Organization grade III. Although its recurrence is common, extracranial metastasis is rare and usually misdiagnosed. The transfer mechanism and pathway are ambiguous; once the metastasis occurs, the prognosis is poor, and there is no effective management. The present case is the first report of concurrent intracranial and pulmonary RM with rapid and widespread metastasis. We hope this report can serve as a helpful reference for clinicians and radiologists. ⋯ Intracranial RM is a relatively rare tumor with the potential for wide intracranial and extracranial transfer. Cystic components and necrosis can be seen in this type of meningioma. Metastatic meningioma should be kept in mind when dealing with isolated lung lesions. This case report may serve as a helpful reference for clinicians and radiologists.

There is an abundance of articles published on meningioma. ⋯ We identified the top 100 most-cited articles on meningioma that may be considered significant and impactful works, as well as the most noteworthy. In addition, we recognized the historical development and advances in meningioma research and the important contributions of various authors, specialty fields, and countries. A large proportion of the most cited articles were written by authors other than neurosurgeons, and many of these articles were published in non-neurosurgery journals.

Recurrent Perimesencephalic Nonaneurysmal Subarachnoid Hemorrhage: Case Report and Review of The Literature.
Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is a benign form of subarachnoid hemorrhage (SAH) with a favorable prognosis. The risk of recurrent hemorrhage of this benign entity is extremely low. ⋯ Despite the PNSAH owning benign clinical manifestations and a favorable outcome, this distinct case of recurrent PNSAH demonstrated that the risk of recurrent hemorrhage of PNSAH does exist, although it is rather low. A conservative approach with close follow-up is still warranted for PNSAH patients.

Rosette-Forming Glioneuronal Tumor of the Fourth Ventricle in Children: Case Report and Literature Review.
Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle is a rare World Health Organization (WHO) grade I neoplasm. Gross total resection (GTR) is the treatment of choice, and there is no firm evidence supporting other treatment options when GTR is not feasible. ⋯ We report a case of chemotherapy administration as a first-line treatment for a subtotally resected RGNT. Chemotherapy may be considered as an adjuvant therapy option for RGNT when GTR cannot be achieved. Furthermore, increased incidence of recurrence in the pediatric population may suggest that the tumor biology of RGNT in children differs from that in adults.

Recovery of oculomotor nerve palsy after microsurgical and endovascular treatment has been studied in numerous small series of predominantly ruptured aneurysms. Little consideration has been given to the distinction between ruptured and unruptured aneurysms. This study examines the influence of treatment modality on oculomotor palsy recovery as a result of unruptured posterior communicating artery aneurysms. ⋯ In this narrative review, surgical clipping of unruptured posterior communicating artery aneurysms was associated with a higher rate of associated oculomotor palsy recovery than was endovascular treatment.
