Research paper thumbnail of Astroblastoma - reviewing literature and one case report

Romanian journal of morphology and embryology = Revue roumaine de morphologie et embryologie, 2018

They are rare neoplasms that affect primarily patients of young ages. The purpose of this research is to highlight the uniqueness and rareness of this pathology and to emphasize on the particularities of one case managed in our Clinic. CASE DESCRIPTION We present the case of a 54-year-old patient with a history of seizures since the age of six years old, who presented on admission with progressive worsening and unresponsiveness to treatment, starting six months prior to presentation. Brain imaging shows a right frontal mass compressing neighboring structures. Gross total resection of the tumor was performed, and histopathological examination of the surgical sample together with immunohistochemist...

Glioblastoma, the most common primary brain tumor, has a rapid growth rate and infiltrative nature that leads to the disorganization of the normal brain network. Neuroplasticity, still not fully understood, is the foundation for the development of brain functions during the growth and recovery of certain brain functions after a brain lesion such as a tumor, trauma, or vascular event. Functional MRI has the capacity to identify the regions that activate at rest or when performing a task. It can determine the extent to which these regions, responsible for a specific function, are impacted by a tumor and eventually after surgical excision. Likewise, it can help evaluate to which extent activation changes when recovery of function occurs. In this article, we aimed to understand the significance of fMRI in the management of...

The utilization of Magnetic Resonance Spectroscopy (MRS) brings an important piece of information to an overall MR study, thus aiding the physician in making an accurate assumption regarding the histological grade of a tumor. The purpose of this study is to verify the reliability of MRS in correctly diagnosing both the nature of tumors and their grade. Material and methods. This is an observational study that was conducted from January 2011 to June 2016 on 49 patients confirmed to be low-grade gliomas (LGG) by pathological examination, who were admitted in our Neurosurgery Department in this period. Both retrospective and prospective data were collected. Inclusion criteria comprise unique tumoral lesion at the moment of diagnosis, follow-up for at least one year. Exclusion criteria included: other types of tumors with any location, patient refusal to undergo histopathological examination of the resected tissue, uncompliant and non-collaborating patients. Of all patient...
