Abstract
Central neurocytoma, a rare intracranial tumor predominantly located in the lateral and third ventricles, presents a diagnostic and therapeutic challenge due to its varied clinical manifestations. We report the case of a 53-year-old male presenting with right upper and lower limb weakness, headaches, blurred vision, and tingling sensations, leading to the diagnosis of central neurocytoma with associated hydrocephalus. Initial evaluation, including magnetic resonance imaging (MRI) and subsequent computed tomography (CT) scans, revealed characteristic features of the tumor. The patient underwent a two-stage surgical intervention, including tumor excision and ventriculoperitoneal shunting, followed by a tracheostomy due to respiratory complications post-surgery. Histopathological examination confirmed the diagnosis of central neurocytoma, prompting multidisciplinary management and further referral for long-term follow-up. This case underscores the importance of comprehensive evaluation, multidisciplinary collaboration, and continued research in optimizing the diagnosis and management of central neurocytomas.

Abstract
Clear cell meningioma (CCM) is a rare histological variant of meningioma. It is commonly located at the cerebellopontine angle and the spine particularly around the cauda equina. Squash cytology finding of meningioma is well-established, however there is sparse literature available on squash cytology of CCM. Here we describe a case of CCM occurring in the lumbar spine in a young woman. Initially, on squash cytology a diagnosis of a low grade glioma favouring an ependymoma was considered. Eventually histopathological examination along with immunohistochemistry helped us reach the diagnosis of a CCM. In this article we discuss the cytomorphology of CCM along with its cytological differentials and the hurdles to an accurate diagnosis.

Abstract
A 51-year-old woman presented with severe dizziness. The brain magnetic resonance image revealed a 5.5 cm multiloculated mass with a thick rim in the left temporal lobe. Cytological examination of frozen diagnosis of the mass showed hypercellular sheets of round and rhabdoid cells in a hemorrhagic background, and two mitotic figures were observed. Histologically, the excised dura-based mass consisted of predominantly round cells with small foci of rhabdoid tumor cells in a pseudoalveolar pattern in a hemorrhagic background, and the cells showed nuclear positivity for signal transducer and activator of transcription 6 as well as frequent mitosis. The mass was diagnosed as a grade 3 solitary fibrous tumor (SFT)/hemangiopericytoma (HPC). The cytological diagnosis of SFT/HPC is challenging because of the heterogeneous cytological findings, such as histological heterogeneity, and because there are no standardized cytological criteria for malignant SFT/HPC. Cytological findings, such as singly scattered small cells, hypercellularity, rare ropy collagen, and round and rhabdoid cells with pseudoalveolar pattern, may assist in the diagnosis of malignant SFT/HPC.

Abstract
Clear-cell meningioma (CCM), an unusual subset of meningioma has prominent, clear-cell morphology. It is a wolf in sheep's clothing characterized by benign histologic attributes, but tendency for recurrence (61%) and metastasis. Therefore, WHO has classified it as grade II meningioma. Fine-needle aspiration cytology diagnosis is simple, rapid, cost-effective and reliable procedure primarily aimed at preoperative diagnosis of advanced and metastatic extracranial tumor. Preoperative and/or intraoperative cytodiagnosis of CCM demand expertise in the evaluation of cytology smears. However in case of intra operative evaluation of squash smears there is a time constraint and a very small tissue material obtained by stereotactic biopsy are available for interpretation. Knowledge of clinical features including age, anatomical locations, neuroimaging findings and cytomorphologic features, are prerequisites for arriving at definitive cytodiagnosis. We describe intra operative squash cytology of CCM in a 16-year-old female, located in cerebello-pontine angle. The diagnosis of CCM offered on squash cytology was subsequently confirmed on histopathology and immunohistochemistry. It typically showed pattern less sheets and groups of polyhedral, clear cells with monomorphic, round nuclei having a bland chromatin and inconspicuous nucleoli. Separation of CCM from other tumors having clear -cell morphology and variants of meningioma is important because of its high recurrence rate and mortality.

The typical and atypical MR imaging findings of central neurocytomas: Report on eighteen cases and review of the literature. Clin Neurol Neurosurg 2016; 146:18-23.

Abstract
There were few studies have documented the MRI features of typical and atypical CNCs for diagnosis and therapeutic modalities. Here, 18 histopathologically confirmed cases of intracranial CNCs (8 men and 10 women with a mean age of 28.3 years, range 10-64 years) were retrospectively analyzed. The histopathological and immunohistochemical features were also assessed. On MR imaging, the 14 typical cases of CNCs showed relatively round, lobulated tumor masses in the body of the right lateral ventricle (5 cases), left lateral ventricle (4 cases), third ventricles (2 cases), and midline (3 cases). These typical CNCs masses contained clusters of cysts of varying sizes and "soap bubble" appearance on T2WI; they showed mild to moderate heterogeneously enhancement on T1WI. The 4 atypical cases of CNCs showed as strongly contrast enhancement of the tumors with the attachment or infiltrate of the wall of the ventricle than the typical benign cases. These atypical CNCs were in the right lateral ventricle (2 cases), left lateral ventricle (1 case), and third ventricle (1 case). Microscopically, the typical CNCs were well-differentiated tumors with benign histological features. The typical and atypical CNCs were composed of uniform, small to medium-sized cells with rounded nuclei and scant cytoplasm. Immunohistochemically, the typical CNCs were strong in Syn immunopositive (14/14) and neuron-specific enolase (12/14). The atypical CNC tumor cells showed malignant behavior and more positive expression of Ki67 than the benign cases. Surgery is the first choice of treatment, and radiotherapy may be beneficial to postoperative patients.
