RESUMEN
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.

The biological origin of cerebellar liponeurocytomas is unknown, and hereditary forms of this disease have not been described. Here, the authors present clinical and histopathological findings of a young patient with a cerebellar liponeurocytoma who had multiple immediate family members who harbored similar intracranial tumors. A 37-year-old otherwise healthy woman presented with a history of progressive headaches. Lipomatous medulloblastoma had been diagnosed previously in her mother and maternal grandfather, and her maternal uncle had a supratentorial liponeurocytoma. MRI revealed a large, poorly enhancing, lipomatous mass emanating from the superior vermis that produced marked compression of posterior fossa structures. An uncomplicated supracerebellar infratentorial approach was used to resect the lesion. Genetic and histopathological analyses of the lesion revealed neuronal, glial, and lipomatous differentiation and confirmed the diagnosis of cerebellar liponeurocytoma. A comparison of the tumors resected from the patient and, 22 years previously, her mother revealed similar features. Cerebellar liponeurocytoma is a poorly understood entity. This report provides novel evidence of an inheritable predisposition for tumor development. Accurate diagnosis and reporting of clinical outcomes and associated genetic and histopathological changes are necessary for guiding prognosis and developing recommendations for patient care.
