Central neurocytomas are rare, relatively benign intraventricular neoplasms composed of uniform round cells with neuronal differentiation. The majority of previously reported central neurocytomas did not recurr after tumor removal and the patients had favorable postoperative outcomes. Only a few
Atypical extraventricular neurocytoma (EVN) is a rare condition characterized by diffuse tumor cell hyperplasia, increased neovascularization, increased necrosis, and aggressive characteristics. A case of a 25-year old man who presented with atypical EVN in his left parietal - occipital flaps is
Six patients with central neurocytoma were retrospectively examined, including diagnosis and treatment process as well as postoperative complications. Clinical follow-ups were performed through telephone calls or outpatient service. Of the 6 patients, a total of 5 patients had 1 or more
BACKGROUND
Neurocytoma is a rare brain neoplasm of neuroepithelial origin that occurs predominantly in the ventricular system adjacent to the interventricular foramen and septum pellucidum. However, extraventricular neurocytoma is an extremely rare entity, with poor clinical, radiologic, and
BACKGROUND
Extraventricular neurocytomas (EVNs) are rare neuronal tumors included as neoplasms in the 2007 World Health Organization (WHO) classification of tumors of the CNS. Although a few case reports describing EVNs have been published, a systematic analysis of MR imaging findings of EVN has not
Extraventricular neurocytoma is a rare entity, most frequently occurring in brain parenchyma outside the ventricular system. The purpose of this study was to characterize the MR imaging findings in a series of 9 patients with EVN verified by results of pathologic examination. All 9 EVNs were
OBJECTIVE
Extraventricular neurocytoma (EVN) is an exceedingly rare tumor. In this study, we sought to characterize the imaging and pathological features of this uncommon tumor.
METHODS
Retrospective review of 18 patients (9 male; 9 female) with pathologically confirmed EVN treated at a single
Extraventricular neurocytoma (EVN) is rare entity with similar biologic behavior and histopathologic characteristics to neurocytomas that occur in the lateral ventricles, according to the 2007 World Health Organization classification. We report the cases of 3 patients with extraventricular
In the publication by the World Health Organization of the histological classification of central nervous system tumors in 1993, several new tumor types were added, including pleomorphic xanthoastrocytoma (PXA), dysembryo-plastic neuroepithelial tumor (DNT), and desmoplastic infantile ganglioglioma
The authors review their experience with magnetic resonance imaging (MRI) of giant lateral ventricular tumours, placing special emphasis on the imaging features that aid in the differential diagnosis. The tumours illustrated include astrocytoma, oligodendroglioma, neurocytoma, subependymoma,
