“…However, in the group below 18 years, the male: female was 2:1, which showed a prominent male predilection. One of the previous reports described a slight male predominance, which was the same with our result [12]. These demographic discrepancies between the studies were probably caused by a selection bias because of the small number of cases.…”

“…Ventricular ependymomas were mostly hyperdense with pronounced contrast uptake. On the contrary, subependymomas were hypodense, mostly without enhancement, but occasionally slight or moderate enhancement was noted, and SEGA also displayed hypodense, rarely hyperdense or mixed imaging characteristics and always in significant degree of contrast enhancement [12]. In accordance with previous reports, all showed hypo-or mixed density, but mostly slight to moderate enhancement.…”

“…Currently, data available in the literature showed that exact diagnosis of ventricular neoplasms (neurocytoma, ependymoma, subependymoma, SEGA) was hardly possible on the CT and MRI images since nearly every variation of imaging characteristics (hypo-or hyperintense, contrast enhancement, cyst, etc.) may be present or entirely absent in a single case [12]. Ventricular ependymomas were mostly hyperdense with pronounced contrast uptake.…”

Clinical and imaging features of subependymal giant cell astrocytoma: report of 20 cases

et al. 2017

Background: Subependymal giant cell astrocytoma (SEGA) is a clinically benign brain tumor associated with tuberous sclerosis complex (TSC). There are still controversies on early diagnosis of the tumor. Methods: CT and MR imaging of 20 patients with pathologically confirmed SEGA were retrospectively reviewed. Two radiologists evaluated the location, shape, size, number, edge, cerebral edema, homogeneous or heterogeneous appearance, attenuation and signal intensity, degree of enhancement and calcification of lesions. Their prognoses were based on clinical observations.

“…Central neurocytomas (CNs) are intraventricular central nervous system (CNS) neoplasms first described by Hassoun et al [1] in 1982 and which are now regarded as a well-established clinicopathological entity and classified as a World Health Organization (WHO) grade II tumor [2]. Typically, they are located in the lateral ventricles in the region of the foramen of Monroe and affect young adults between 20 and 40 years of age [2].…”

“…Typically, they are located in the lateral ventricles in the region of the foramen of Monroe and affect young adults between 20 and 40 years of age [2]. Although uncommon, representing 0.25-0.5% of all intracranial tumors [3,4], CNs are considered to have a favorable prognosis [5]; therefore, a total resection is warranted in order to ensure an excellent outcome.…”

Background: Central neurocytomas (CNs) are infrequent intraventricular tumors with features of neuronal differentiation that affect young adults and have an excellent prognosis after total resection. The main differential intraoperative diagnoses are oligodendrogliomas, ependymomas and non-Hodgkin's lymphomas; therefore, an accurate and precise intraoperative diagnosis is essential, making the cytologic features the hallmark for cytopathologists, surgical pathologists and neurosurgeons alike. Seven previous reports have described 18 cases of CNs and have addressed the cytodiagnostic criteria during intraoperative assessment in the English medical literature. Cases: Three patients (23 years old/male, 29 years old/female and 28 years old/male) were evaluated during intraoperative assessment as CNs. They showed intraventricular tumors that measured 6.5, 3.5 and 6.6 cm, respectively. The cytologic features common in these cases were: (1) monotonous or isomorphic round cells, (2) small nuclei with stippled or granular chromatin, and (3) acellular fibrillary areas or neuropil (islands). Other cytologic features often encountered were: rosette-like structures, micronucleoli, perinuclear haloes, well-formed capillary-sized vessels and calcifications. Conclusion: Differential diagnosis of CNs can be a diagnostic challenge. The integration of radiologic imaging and touch preparations taking into account specific cytologic features and frozen sections is necessary for an optimal intraoperative assessment.
