Abstract
BACKGROUND The literature on cerebellar liponeurocytoma (CL) has never been systematically assessed using bibliometric analytic methodologies. We quantitatively analyzed the major trends and scientific output regarding CL, highlighting potential avenues for research. METHODS Elsevier's Scopus database was used to collect all published studies relevant to cerebellar liponeurocytoma from 1978 to 2021. The specific bibliometric parameters were extracted and analyzed with R v4.1.2. RESULTS Our search yielded 108 documents published in 67 sources from 1978 to 2021. The annual growth rate of publications regarding CL has been 7.47% per year since 1978. Journals with the most publications on CL include Clinical Neuropathology and Neurology India (n = 5), followed by Acta Neuropathologica and Journal of Neuro-oncology (n = 4). A total of 529 authors have published on CL and they have been cited 598 times. The 10 most influential authors in the field were determined using their total number of citations and the local H-index. Kleihues P has the highest number of citations (n = 177) with a local H index of 3, followed by Chimelli L with 167 citations and a local H index of 4. Davis DG has 149 citations and a local H index of 3. China had the most single country publications followed by India, Italy, and the USA. France and Austria have the most multiple country publications followed by China, Tunisia, Brazil, United Kingdom, Egypt, and Israel. CONCLUSIONS Our study is the first bibliometric analysis evaluating the present literature and publication trends in CL. Generally, the current literature has a few studies regarding CL relative to other neuro-oncological pathologies. This can be due to the low incidence of the disease and highlights a need for high volume database studies that can offer high quality evidence on the subject.

Abstract
Introduction Cerebellar liponeurocytoma is a rare tumor of the central nervous system occurring mainly in the posterior fossa, which shows neuronal and variable astrocytic differentiation, along with foci of lipomatous differentiation. Case presentation Herein, we describe a 50-year-old female patient who presented to the hospital complaining of headache, tinnitus, and vertigo with positive cerebellar signs. MRI revealed a left cerebellar tumor. After tumor resection, histological examination and immunohistochemistry were done and the diagnosis of cerebellar liponeurocytoma was confirmed. Discussion Liponeurocytoma may be mistaken as a medulloblastoma with lipidized cells or a lipomatous ependymoma. Histopathological examination, reinforced by immunohistochemistry and electron microscopy, are required to distinguish between these entities. The rarity of this tumor and paucity of pertinent information regarding its biological potential and natural history have resulted in the application of various treatment modalities. Conclusion Liponeurocytoma is a rare benign tumor with cerebellum is the typical site for it. Although surgery is the treatment of choice; however, postoperative radiotherapy may have a role in case of incomplete tumor resection or recurrence. Cerebellar liponeurocytoma is a rare benign tumor that mainly occurs in the posterior fossa. Surgery is the first line in management. Postoperative radiotherapy has a role in case of incomplete tumor resection or recurrence.

Abstract
BACKGROUND Liponeurocytoma is an uncommon tumor of the central nervous system. It is very rare for this tumor to originate within the lateral ventricle. In the context of the rarity of this tumor entity, this review article aims to summarize the clinical, radiological, and pathological features of lateral ventricular liponeurocytoma to facilitate its diagnosis and management. METHODS Here, we conduct a systematic literature review using the Pubmed, Scopus, and Cochrane Library database for all cases of lateral ventricular liponeurocytoma. A case illustration complements this review. RESULTS The described cases from 1997 onward include 14 cases that have been published in full papers in the English literature. Six additional cases are reported in short English abstracts in full non-English papers, and one case was described in a central neurocytoma report. There is a definite male predominance of 70% (14 male) and a mean age of 37 years (range 24-62). Heterogenous enhancement and signals in magnetic resonant images (MRI) are the radiological characteristics. In all reported cases, the presence of lipocytes and fat vacuoles is considered the paramount histopathological feature. Total surgical resection was achieved in 80% (12 out of 15) of the cases. Only two cases (including ours) received radiation therapy. Recurrence was seen in two patients during follow-up that was treated by radiation therapy in one and surgery in the other. The proliferation index is mostly below 5% in all cases, with the Ki-67 range between<1% to 10%. CONCLUSIONS Lateral ventricular liponeurocytoma has been treated effectively by surgical resection in a limited number of cases. The decision for radiation therapy is based on a high proliferation index and tumor recurrence.

Abstract
BACKGROUND Liponeurocytoma is a very rare tumor classified as grade II (neuronal and mixed neuronal-glial tumors) according to 2016 World Health Organization classification of tumors of the central nervous system. The median age at detection is 50 years, and the most frequent location is the posterior cranial fossa, especially within the cerebellar hemispheres; liponeurocytomas arising in the cerebellopontine angle (CPA) are exceptional. CASE DESCRIPTION Here we report the clinical, radiological, and pathological characteristics of a CPA liponeurocytoma in a 35-year-old woman, as well as a review of the literature. This unusual cisternal location raises the issue of the differential imaging diagnosis with much more common CPA tumors (e.g., meningiomas, vestibular schwannomas, ependymomas, epidermoid cyst, hemangioblastomas, medulloblastomas). CONCLUSION To the best of our knowledge, 59 cases of cerebellar liponeurocytomas have been reported to date, which include only 6 cases of CPA liponeurocytomas. Treatment relies on total removal whenever possible, with an excellent prognosis, but a high MIB-1 index (>10%) and/or incomplete tumor resection are the main adverse prognostic factors.

Abstract
Supratentorial liponeurocytoma is a rare tumor, predominantly appearing in young males. It most commonly affects the lateral ventricles, with involvement of the third ventricle being exceptional. It is defined as a low-grade neuroglial tumor, with areas of associated lipomatosis. The most common clinical manifestation is that resulting from the presence of secondary intracranial hypertension and hydrocephalus. We present the first case reported in Spain of this tumor type and one of the few appearing in the literature so far. We report the case of a 33-year-old male patient, suffering from crural sensitive symptoms and recent onset headache. The radiographic study revealed the presence of a large supratentorial tumor; intraventricular, multicystic, heterogeneous and with areas of associated lipomatosis. The patient underwent surgery and complete tumor resection was achieved. The definitive diagnosis was of supratentorial liponeurocytoma. The presence of a supratentorial intraventricular tumor with areas of fatty degeneration should lead us to consider this type of tumor in the differential diagnosis. Complete tumor resection is considered to be the treatment of choice.

Abstract
We report a rare case of cerebellar liponeurocytoma with an unusually aggressive histopathology. A 49-year-old man presented with a four-month history of headache, vertigo, and progressive swaying gait. Magnetic resonance imaging showed a 3×3.5 cm sized relatively well-demarcated round mass lesion in the fourth ventricle, characterized by high signal intensity on T2-weighted images. Postcontrast images revealed strong enhancement of the solid portion and the cyst wall. The patient underwent suboccipital craniectomy and tumor removal. The pathologic diagnosis was cerebellar liponeurocytoma. Adjuvant radiotherapy was offered due to concerns related to the high proliferative index (Ki-67, 13.68%) of the tumor. At the last routine postoperative follow-up visit (12 months), the patient complained of no specific symptom and there was no evidence of tumor recurrence. However, long-term follow-up and the analysis of similar cases are necessary because of the low number of reports and the short follow-up of cases.
