Intracranial neurenteric cyst with an enhanced mural nodule and melanin pigmentation: radiological-pathological correlation.
An intracranial neurenteric cyst (NC) is a rare congenital benign lesion that usually has a well-demarcated cystic appearance without contrast enhancement on magnetic resonance imaging (MRI). In particular, an intracranial NC with an enhanced mural nodule is extremely rare. ⋯ We present this rare case and emphasize that an NC should be considered in the differential diagnosis of intracranial cystic lesions with an enhanced mural nodule.

Basilar perforator aneurysms: Presentation of 4 cases and review of the literature.
Basilar perforator aneurysms (BPAs) are rare lesions that present a therapeutic challenge. We present 4 cases of ruptured BPAs treated either conservatively or by flow diverter deployment and review the literature. ⋯ Ruptured BPAs are rare lesions that may heal spontaneously or be associated with spontaneous ischemic brainstem stroke or rerupture. These lesions can be managed conservatively initially with flow diverter deployment the most suitable therapeutic alternative in selected cases. Larger studies are needed to fully understand the natural history and refine the therapeutic strategy for these lesions.

Cervical Osteochondroma Causing Myelopathy in Adults: Management Considerations and Literature Review.
Osteochondromas are the most frequent benign bone tumors but only rarely occur along the spinal column and even more rarely induce symptoms from spinal cord compression. ⋯ We discuss the role of surgical intervention, management, and postoperative follow-up in adult patients with cervical osteochondromas. Recommended management includes radiographic imaging and surgical intervention, particularly when evidence of spinal cord impingement occurs. Consistent postoperative follow-up is necessary to ensure appropriate recovery of neurologic function. Surgical management of cervical osteochondromas typically results in excellent and stable clinical outcomes with rare recurrence.

Angiocentric Glioma in an Elderly Patient: Case Report and Review of the Literature.
Angiocentric glioma is a very uncommon low-grade tumor, predominantly occurring in pediatric patients, that was first described in 2005 and was codified 2 years later as a new central nervous system primary tumor. We herein report an exceptionally rare case of an elderly patient with angiocentric glioma. Only one additional case of angiocentric glioma in a patient older than 65 years has been hitherto reported. ⋯ Considering the morphologic and immunohistochemical data, the final pathologic diagnosis was angiocentric glioma. Furthermore, a thorough review of the literature was performed with the purpose of updating and summarizing the main clinical, radiologic, and pathologic features of this rare tumor.

Mixed tumors of adenomatous and neuronal cells in the sellar region are an uncommon finding. The origins of these heterogeneous tumors are unknown, and management remains unsettled. We report a very rare case of anterior gray matter pituicytic heterotopia with monomorphic anterior pituitary cells that likely represents a variant of nonsecreting pituitary adenoma neuronal choristoma (PANCH) with no ganglion cells. We also review the current literature for the various clinical presentations of PANCH. ⋯ The overall findings were most consistent with a variant of PANCH. At a postoperative follow-up of 4.5 years, there was resolution of visual symptoms, and the residual sellar mass was stable on MRI. Neuronal choristoma is hypothesized to originate from embryonal pituitary or hypothalamus, or by differentiation from pituitary adenoma cells. Surgery is the cornerstone of management, and the clinical course appears to be similar to that of nonfunctioning pituitary adenoma in reported cases.
