We report two patients with central neurocytomas at an uncommon location in the brain. The first, a 58-year-old man presenting with signs and symptoms of increased intracranial pressure, had a tumor located at the pineal region. The second, a 21-year-old woman with tumor in the aqueductal region had worsening migraine-like headaches and diplopia. Both patients had obstructive hydrocephalus treated by neuroendoscopic third ventriculostomy and biopsy of the tumors. No additional treatment was done. We conclude that neurocytomas should be considered in the differential diagnosis of tumors located in the pineal and aqueductal regions.

Background: Less than 1% of all intracranial tumors are in the pineal region. Papillary tumor of the pineal region is considered one of four pineal parenchymal tumors according to the 2007 World Health Organisation classification of central nervous system tumors. It is mostly seen in the middle age and it is rare under the age of 17 in the literature. In this report, we aim to present a case with papillary tumor of the pineal region with both CT and MRI findings, and discuss the differential diagnosis. Case report: A 17-year-old female patient who underwent a treatment of ventriculoperitoneal shunt due to hydrocephalus 18 months ago applied to the neurosurgery clinic with nausea, vomiting, sensorineural hearing loss and Parinaud syndrome continuing through 1 month. Computed tomography (CT) and magnetic resonance imaging (MRI) have been applied. A 58x31x38 mm mass with cystic and mild hyperdense soft tissue components was observed in the localization of pineal gland and posterior comissure on non-enhanced CT. MRI examination revealed that the mass filled the pineal region, contained solid and large cystic components, and hyperintense on T1-weighted images. After intravenous contrast media injection, the mass enhanced more peripherally. DW-MRI showed that there is a diffusion restriction in some parts of the soft tissue components. The mass was totally resected, and pathology report revealed that it is a papillary tumor of the pineal region. Conclusion: When a T1-weighted hyperintense and CT hyperdense mass with cystic and solid components is seen in the pineal region, even if it is rare, papillary tumor should also be considered in the differential diagnosis after exclusion of other hyperintense lesions in T1-weighted imaging.

Pineoblastomas are uncommon pineal tumors, which demonstrate rapid growing and poor prognosis. We report the case of a 43-year-old man with an enhancing pineal region mass, which showed restriction of the diffusion on diffusion-weighted (DW) MR images. The surgical biopsy defined the diagnosis of pineoblastoma and the therapy was initiated with radiation and chemotherapy. Three months later, the follow-up MR imaging showed areas suggestive of necrosis and the DW images demonstrate no significant areas of restricted diffusion. The differential diagnosis of pineal region masses that could show restriction of diffusion is discussed.

✓ A case of papillary pineocytoma is presented. It is necessary to be aware of this unusual histological type of pineocytoma in order to make a differential diagnosis among other types of papillary tumors that arise in the pineal region.

Background: Accurate diagnosis of brain tumor is crucial for adequate surgical strategy. Our institution follows a comprehensive preoperative evaluation based on clinical and imaging information. Methods: To assess the precision of preoperative diagnosis, we compared the “top three list” of differential diagnosis (the first, second, and third diagnoses according to the WHO 2007 classification including grading) of 1061 brain tumors, prospectively and consecutively registered in preoperative case conferences from 2010 to the end of 2017, with postoperative pathology reports. Results: The correct diagnosis rate (sensitivity) of the first diagnosis was 75.8% in total. The sensitivity of the first diagnosis was high (84–94%) in hypothalamic-pituitary and extra-axial tumors, 67–75% in intra-axial tumors, and relatively low (29–42%) in intraventricular and pineal region tumors. Among major three intra-axial tumors, the sensitivity was highest in brain metastasis: 83.8% followed by malignant lymphoma: 81.4% and glioblastoma multiforme: 73.1%. Sensitivity was generally low (≦60%) in other gliomas. These sensitivities generally improved when the second and third diagnoses were included; 86.3% in total. Positive predictive value (PPV) was 76.9% in total. All the three preoperative diagnoses were incorrect in 3.4% (36/1061) of cases even when broader brain tumor classification was applied. Conclusion: Our institutional experience on precision of preoperative diagnosis appeared around 75% of sensitivity and PPV for brain tumor. Sensitivity improved by 10% when the second and third diagnoses were included. Neurosurgeons should be aware of these features of precision in preoperative differential diagnosis of a brain tumor for better surgical strategy and to adequately inform the patients.

The broadest application of transmission electron microscopy (EM) in diagnostic medicine is the identification of tumors that cannot be classified by routine light microscopy. EM is useful in the evaluation of approximately 10% of human neoplasms, but the extent of its contribution varies considerably. It may provide a specific diagnosis that can not be reached by other means, but in contrast, the information obtained from ultrastructural study of some 10% of tumors does not significantly add to that available from light microscopy. Most cases fall somewhere between these two extremes: EM may correct a light microscopic diagnosis, or serve to narrow a differential diagnosis by excluding some of the possibilities considered by light microscopy. It is particularly important to correlate the EM findings with data from light microscopy, clinical examination, and other diagnostic procedures.

Healthcare professionals require a thorough understanding of stuttering since they frequently play an important role in the identification and differential diagnosis of stuttering for preschool children. This paper introduces The Preschool Stuttering Screen for Healthcare Professionals (PSSHP) which highlights risk factors identified in the literature as being associated with persistent stuttering. By integrating the results of the checklist with a child’s developmental profile, healthcare professionals can make better-informed, evidence-based decisions for their patients.
