The Natural History and Treatment Guidelines of Cerebellar Liponeurocytoma—A Case Report

Open Journal of Modern Neurosurgery 2011年第2期1卷 10-16页

作者： Or Cohen-Inbar Euvgeni Vlodavsky menashe zaaroor 不详

Background and Importance: Lipomatous medulloblastoma (cerebellar liponeurocytoma) is a rare cerebellar tumor, with only twenty-nine cases reported, considered a distinct variant of medulloblastoma. The few cases described support an indolent nature for this tumor. We aim at defining the optimum treatment strategy and long-term behavior for this tumor entity. Clinical presentation: A 74 years old male presented on September 2010 complaining of mild dizziness and headache slowly progressing over a few months. This gentleman was operated on at our department some 18 years ago for a right cerebellar hemispheral lesion, defined as a liponeurocytoma. This patient received no adjuvant treatment. Current magnetic resonance imaging (MRI) studies disclosed a right hemispheral cerebellar mass, locally recurrent in the original surgical tumor bed. Gross total resection of the tumor was accomplished through a suboccipital craniotomy, with complete resection of the lesion. The histopathological diagnosis was defined as cerebellar liponeurocytoma. No adjuvant therapy was given as initially, after the first operation. Currently, the patient is alive, fully alert with minimal neurological deficits, Barthel index 90, Kernofsky performance status of 90 and with no evidence of disease on neuroimaging. Conclusion: This patient portrays this tumor’s natural history after surgical intervention with no adjuvant treatment, being the longest reported follow-up and recurrence. This distinct variant of medulloblastoma appears to have a uniquely favorable prognosis, even without adjuvant therapy. A complete surgical resection with close follow-up seems both sufficient and prudent.

Background:Applying ultrasonic imaging system during surgery requires the poring of saline,performing the measurement,and acquiring data from its display—which requires time and is highly“performer dependent,”i.e.,the measure is of a subjective nature.A new ultrasonic device was recently developed that overcomes most of these drawbacks and was successfully applied during tumor-in-brain *** purpose of this study was to compare the two types of US devices and demonstrate their ***:The study was performed in the following stages:(i)an ex vivo experiment,where slices of the muscle and brain of a young porcine were laid one on top the *** and border depths were measured and compared,using the two types of US instruments.(ii)During human clinical neurosurgeries,tumor depth was compared by measuring it with both devices.(iii)Following the success of stages(i)and(ii),using solely the new US device,the tumor thickness was monitored while its ***,Pearson’s coefficient,average,mean,and standard deviation were applied for statistical ***:A high correlation was obtained for the distances of tissue borders and for their respective *** these ultrasonic devices during neurosurgeries,tumor depths were monitored with high similarity(87%),which was also obtained by Pearson’s correlation coefficient(0.44).The new US device,thanks to its small footprint,its remote measurement,and the capability of monitoring intraoperatively and in real-time,provides the approach to tumor’s border before its complete ***:The new US device provides better accuracy than an ultrasonic imaging system;its data is objective;it enables to control the residual tumor thickness during its resection,and it is especially useful in restricted *** features were found of great help during a tumor-in-brain surgery and especially in the final stages of tumor’s resection.
