Lumbar Paravertebral Muscle Pain Management Using Kinesitherapy and Electrotherapeutic Modalities.

BACKGROUND: Low back pain is considered a public health problem internationally. Low back pain is a cause of disability that occurs in adolescents and causes negative effects in adults as well. The work environment and physical and psychosocial factors can influence the occurrence and evolution of low back pain. METHODS: The purpose of this paper is to highlight the physiological and functional changes in young adults with painful conditions of the lumbar spine, after using exercise therapy. The study was of the longitudinal type and was carried out over a period 6 months in an outpatient setting. The rehabilitation treatment included electrotherapeutic modalities and kinesitherapy. RESULTS: The results obtained when evaluating each parameter, for all moments, show statistically significant values in both groups. The results obtained regarding the relationship between the therapeutic modalities specific to rehabilitation medicine and low back pain are consistent with those reported in studies. CONCLUSIONS: Depending on the clinical-functional status of each patient, kinesitherapy can accelerate the heart rate and increase the blood pressure and oxygen saturation of the arterial blood, values that can later return to their initial levels, especially through training.

Epidemiological and histopathological aspects of ocular melanomas in Northeastern Romania.

Ocular melanoma is a rare but complex disease in current medical practice. Our retrospective study spans over a period of 28 years and analyzed uveal and conjunctival melanomas that were consecutively admitted, diagnosed, and treated in the 2nd Ophthalmology Clinic of Prof. Dr. Nicolae Oblu Emergency Clinical Hospital, Iasi, Romania. The patients were selected from the records of the Department of Pathology of our Hospital, being diagnosed by standard histopathological techniques. The aim of this study was to summarize the epidemiological and pathological aspects of uveal and conjunctival melanomas in Northeastern region of Romania. In our study, we did not notice a predilection of uveal and conjunctival melanoma to one particular gender. The most common histological subtypes of ocular melanomas were the heavily pigmented spindle cell subtype, followed by the epithelioid subtype. Our patients sought medical help in a timely manner, before the systemic invasion of the disease could develop.

Cerebellar Abscess Secondary to Cholesteatomatous Otomastoiditis-An Old Enemy in New Times.

Chronic otitis with cholesteatoma is a potentially dangerous disease that can lead to the development of intracranial abscesses. Although cerebellar abscess is half as common as cerebral abscess, it is known for its particularly difficult diagnosis, which requires the visualization of the pathological process continuity from the mastoid to the posterior fossa. In this article, we present an extremely rare case from the literature of cholesteatomatous otomastoiditis complicated with meningitis and cerebellar abscess, along with the description of technical surgical details for the plugging of the bony defect between the mastoid and posterior fossa with muscle and surgical glue. The particularity of this case lies in the late presentation to the doctor of an immunocompetent patient, through a dramatic symptomatology of life-threatening complications. We emphasize the importance of responsibly treating any episode of middle ear infection and considering the existence of underlying pathologies. In such cases, we recommend additional neuroimaging explorations, which can prevent potentially lethal complications. The treatment of such intracranial complications must be carried out promptly and requires collaboration between a neurosurgeon and an ENT surgeon.

The Role of the NF-kB Pathway in Intracranial Aneurysms.

The pathophysiology of intracranial aneurysms (IA) has been proven to be closely linked to hemodynamic stress and inflammatory pathways, most notably the NF-kB pathway. Therefore, it is a potential target for therapeutic intervention. In the present review, we investigated alterations in the vascular smooth muscle cells (VSMCs), extracellular matrix, and endothelial cells by the mediators implicated in the NF-kB pathway that lead to the formation, growth, and rupture of IAs. We also present an overview of the NF-kB pathway, focusing on stimuli and transcriptional targets specific to IAs, as well as a summary of the current strategies for inhibiting NF-kB activation in IAs. Our report adds to previously reported data and future research directions for treating IAs using compounds that can suppress inflammation in the vascular wall.

Predictor factors for recurrence in atypical meningiomas.

BACKGROUND AND OBJECTIVES: Atypical meningiomas (AMs), World Health Organization (WHO) grade 2, are a group of tumors with uneven and unpredictable clinical behavior. Our aim was to analyze possible tumor recurrence predictors, and to identify factors that improve progression-free survival (PFS). PATIENTS, MATERIALS AND METHODS: Our retrospective study included 81 patients followed up in the Prof. Dr. Nicolae Oblu Emergency Clinical Hospital, Iasi, Romania, between 1 January 2010 and 31 December 2020. The histopathological specimens were reviewed according to the WHO 2021 criteria. Analyses included clinical, imaging, pathological and surgical factors. RESULTS: The tumor recurred in 53.1% of the 81 cases within 60 months of surgery. Tumor location (p<0.000), tumor volume (p<0.010), extent of surgical resection (p<0.000) and dural sinus invasion (p<0.001) were predictive factors of recurrence. Gross total resection (Simpson grade I and II) was achieved in 59.2% of patients. Patients with the tumors located in the brain convexity and volume <26.4 cm³ had better survival rates up to recurrence. PFS showed a significant relationship between Simpson grade I-III and biopsy (p<0.000) and was statistically influenced by tumor volume and location, and dural sinus invasion. CONCLUSIONS: AMs are a heterogeneous group of tumors, and we identified posterior fossa location, volume ≥26.4 cm³, Simpson grade III and IV resection and dural sinus invasion as predictive factors for relapse and a shorter PFS. Whereas certain characteristics provide some prognostic value, future molecular characterizations of AMs are necessary, which will support the clinical decision-making process.

A cases series of endovascular and microsurgical combined treatment of intracranial aneurysms.

OBJECTIVE: Our scientific paper is aimed at describing multimodal treatment of intracranial aneurysms represented by microsurgery and endovascular therapy. PATIENTS, MATERIALS AND METHODS: We report four cases of intracranial aneurysms treated in our Department of Neurosurgery by microsurgery (clipping) and endovascular treatment (coiling), through the joint efforts of a team of highly skilled neurosurgeons. RESULTS: Mixed treatment has been imposed by the complications we were presented with, resulting from either of the two surgical methods employed. CONCLUSIONS: Although endovascular surgery is considered a newer treatment method, favored by many practitioners, and preferred by patients, there are situations where open surgery is still required. There are certain situations were using one of the surgical methods fails and a complementary procedure is required for a secure and successful treatment. The cases reported here will demonstrate the utility of combining the two procedures.

The Evolution of Pituitary Gland Surgery from the Ancients to the Millennials.

Located at the base of the skull, the pituitary gland has a long and controversial history, not only in terms of its anatomy, but especially in the functions it performs and in the attempt to approach it surgically. Considered by Galen of Pergamon to have a role in releasing waste products of the brain, a theory accepted until the 17th century, the pituitary gland became a separate entity once with the anatomical descriptions of the famous Andreas Vesalius. At the beginning of the 18th century, researches of the time began to be more and more interested in this gland, trying to identify its functions, and at the same time correcting the traditional theories that were wrong or incomplete. Later, they turned their attention to experimental animal studies that represented the germinal nucleus for the transcranial and endoscopic pituitary surgery. In this review, an attempt has been made to record the entire history of anatomy, physiology and surgery of the pituitary gland, from antiquity to the current day's surgical techniques.

Depiction of Branched-Chain Amino Acids (BCAAs) in Diabetes with a Focus on Diabetic Microvascular Complications.

Type 2 diabetes mellitus (T2DM) still holds the title as one of the most debilitating chronic diseases with rising prevalence and incidence, including its complications such as retinal, renal, and peripheral nerve disease. In order to develop novel molecules for diagnosis and treatment, a deep understanding of the complex molecular pathways is imperative. Currently, the existing agents for T2DM treatment target only blood glucose levels. Over the past decades, specific building blocks of proteins-branched-chain amino acids (BCAAs) including leucine, isoleucine, and valine-have gained attention because they are linked with insulin resistance, pre-diabetes, and diabetes development. In this review, we discuss the hypothetical link between BCAA metabolism, insulin resistance, T2DM, and its microvascular complications including diabetic retinopathy and diabetic nephropathy. Further research on these amino acids and their derivates may eventually pave the way to novel biomarkers or therapeutic concepts for the treatment of diabetes and its accompanied complications.

Brain Tuberculosis: An Odyssey through Time to Understand This Pathology.

Tuberculosis is a contagious disease that has been a concern for humanity throughout history, being recognized and referred to as the white plague. Since ancient times, starting with Hippocrates and Galen of Pergamon, doctors and scientists have attempted to understand the pathogenesis of tuberculosis and its manifestations in the brain. If, in the medieval period, it was believed that only the touch of a king could cure the disease, it was only in the early 17th and 18th centuries that the first descriptions of tuberculous meningitis and the first clinico-pathological correlations began to emerge. While the understanding of neurotuberculosis progressed slowly, it was only after the discovery of the pathogenic agent in the late 19th century that there was an upward curve in the occurrence of treatment methods. This review aims to embark on an odyssey through the centuries, from ancient Egypt to the modern era, and explore the key moments that have contributed to the emergence of a new era of hope in the history of neurotuberculosis. Understanding the history of treatment methods against this disease, from empirical and primitive ones to the emergence of new drugs used in multi-drug-resistant tuberculosis, leads us, once again, to realize the significant contribution of science and medicine in treating a disease that was considered incurable not long ago.

Clinicopathological characteristics and prognostic factors of atypical meningiomas with bone invasion: a retrospective analysis of nine cases and literature review.

BACKGROUND: Meningiomas are the most common primary neoplasms of the central nervous system in adults, arising from the arachnoid cap cells. Thus, grade 2 meningiomas are situated on the border between benignity and malignancy. Among the many prognostic factors that have been investigated in these tumors, bone invasion is one of them. OBJECTIVE: The aim of our study was to identify whether bone invasion influences tumor recurrence and progression-free survival (PFS) in patients with atypical meningiomas (AMs). PATIENTS, MATERIALS AND METHODS: Out of 81 patients with AMs followed over a period of five years, we identified nine patients with bone invasion. We analyzed their demographic, clinical, imaging, and pathological characteristics, such as age, gender, radiological aspects, morphological features, extent of resection, recurrence rate, and PFS over a follow-up period of 60 months. Bone invasion was determined based on preoperative, surgical, and pathological reports. RESULTS: Out of the nine patients with bone invasion, four had convexity meningiomas, four had parasagittal meningiomas and one had a falcine meningioma. Regarding tumor recurrence∕progression, most patients (n=6) recurred within the first 24 months after surgery. Our study showed that the early recurrence/progression of tumor (at 12 months) correlated with extensive presence of malignancy criteria, especially with the presence of 15-18 mitoses∕10 high-power fields, as well as with large foci of spontaneous necrosis, but also with tumor bone infiltration, extensive bone lamellae destruction, and tumor infiltration of adjacent muscle with its atrophy due to tumor compression. Patients with bone invasion had a PFS of 29.3 months, compared to patients without invasion who had a higher PFS (49.3 months). Significant statistical associations were observed between bone invasion and tumor recurrence (p=0.002) and PFS (p=0.004). CONCLUSIONS: Our study emphasizes the importance of a thorough histopathological examination of the surgical specimen, which can provide significant data for the assessment of the progression of an AM [World Health Organization (WHO) grade 2] with bone invasion. AM infiltration in adjacent bone and muscle increases the rate of tumor recurrence and decreases PFS over a follow-up period of 60 months.

Humps and bumps of head: review of meningiomas of the scalp.

Meningiomas are a type of tumor that arises from meningothelial cells and primarily develops in intracranial space, being some of the most common benign tumors of the central nervous system. However, meningiomas can rarely occur on the scalp and are called primary cutaneous meningiomas. Since the pathogenesis of these lesions is still uncertain, these tumors still pose challenges in terms of histopathological diagnosis. In this review, we will discuss the main cases of scalp meningiomas in the literature, their classification, pathological and immunohistochemical diagnosis, differential diagnosis with other scalp lesions and the most effective treatment. This study highlights the importance of immunohistochemistry in the differential diagnosis of skin lesions located on the scalp.

Anatomical study of circle of Willis on fresh autopsied brains. A study of a Romanian population.

Because the circle of Willis (CoW) supplies blood to the brain in case of occlusion of one of the cerebral arteries, identification of any change in its classical shape could be useful in the assessment of cerebrovascular morbidity. The purpose of our research was to study the anatomical variants of CoW identified on fresh brains obtained at the clinical autopsies of adult deceased patients belonging to a specific population (Northeastern region of Romania), as no data are available for Romania population up to date. The study group included consecutive patients who died in Prof. Dr. Nicolae Oblu Emergency Clinical Hospital, Iasi, Romania, due to medical causes between January 1, 2014 and June 30, 2016, to whom a clinical autopsy was performed. From a total of 96 circles of Willis, 29.17% presented an atypical morphology. We identified eight types of anatomical variants, which affected simultaneously both the posterior and the anterior parts of CoW in 46.42% of cases. The most frequent anatomical variants were hypoplasia (20.91%), followed by the absence of an artery (3.06%), and partially fetal type artery (2.04%). 67.86% of atypical CoW exhibited more than one anatomical variant of an artery in one circle. We identified nine of the 23 morphological patterns that were published to date, and also nine new types. Our research proved that in the population living in the Northeastern part of Romania the anatomical variations of circles of Willis are very polymorphic, with particular morphological aspects.

Complete oculomotor nerve palsy - first manifestation of gastric adenocarcinoma: clinical experience and literature review.

The diagnosis and management of the alteration of the normal function of the oculomotor nerve (third cranial nerve) varies depending on the characteristics of the paralysis, the age of the patient, and the associated symptoms and signs. Oculomotor nerve palsy may be caused by lesions located anywhere from the oculomotor nucleus to the termination of the third nerve in the extraocular muscles. Although there have been significant advances in neuroimaging to facilitate early diagnosis, the management of a patient presenting with isolated oculomotor palsy is still challenging. This review tackles the case of a 52-year-old patient, with a history of pulmonary tuberculosis (at the age of five), referred to the Department of Ophthalmology, St. Spiridon Emergency Clinical Hospital, Iasi, Romania. The patient had diplopia accompanied by right eyelid ptosis, symptoms that began suddenly 10 days before hospitalization. The clinical examination showed right eye grade II palpebral ptosis, exotropia with limitation of eyeball movements in adduction, supra-∕infraduction. Biomicroscopic examination of the anterior pole revealed the presence of anisocoria and light-near dissociation on the affected side. Numerous investigations were performed to identify the cause, starting with tumoral markers, which were within normal limits. Magnetic resonance angiography (MRA) was performed, and posterior communicating artery aneurysm was ruled out. The endocrinology examination and hormonal laboratory tests were also within normal parameters. Due to suspicions of generalized tuberculosis raised by the infectious disease doctor or presence of secondary lesions, thoraco-abdomino-pelvic computed tomography (CT) scan with contrast agent was done and its findings required gastroenterological exploration. After various explorations, the certainty diagnosis was set by histopathological examination, which revealed gastric adenocarcinoma.

Thymus pathology in myasthenia gravis with anti-acetylcholine receptor antibodies and concomitant Hashimoto's thyroiditis. A four-case series and literature review.

OBJECTIVE: Identifying the morphological features of thymus in patients with myasthenia gravis (MG) with anti-acetylcholine receptor (AChR) antibodies and concomitant Hashimoto's thyroiditis (HT), which were recruited from a single surgical unit of a tertiary referral hospital located in the North-Eastern region of Romania, over a period of 11 years. PATIENTS, MATERIALS AND METHODS: We retrospectively reviewed clinical, imaging, laboratory, thymic pathology, and outcome data that were obtained from medical records of patients with MG and concomitant HT, to whom a thymectomy was performed for a suspected thymic lesion. All the surgical interventions were done in the Third Clinic of Surgery, St. Spiridon Emergency County Hospital, Iasi, Romania, for an 11 years' period, i.e., from January 1, 2000 and December 31, 2010. RESULTS: Four patients (three females and one male) were included. The mean age of the patients at the time of their thymectomy was 40.25 years. Of all patients, 75% had moderate or severe MG, 100% had anti-AChR antibodies, and an electromyographic decrement greater than 25%. All patients have been diagnosed with HT in their past medical history by a full thyroid panel [high thyroid-stimulating hormone (TSH) values, low free thyroxine (fT4) values, and the presence of the anti-thyroid antibodies] and all of them have been treated with Euthyrox. Our four patients expressed different MG subtypes, each of them being associated with different thymus pathology. Thoracic computed tomography (CT) scan revealed heterogeneous mediastinal masses and established the correct diagnosis only in 25% of cases. The pathological exams also revealed a heterogeneous pattern of thymic lesions. In contrast with other studies, our patients with MG with anti-AChR antibodies and concomitant HT presented atrophic thymus more frequently (50%), but with particular morphological changes of Hassall's corpuscles. Also, 25% of cases were diagnosed with thymic lympho-follicular hyperplasia (TLFH) associated with thymic epithelial hyperplasia. In B2 thymoma, neoplastic epithelial cells expressed cytokeratin 19 (CK19) immunoreactivity, high Ki67 labeling index and strong p63 immunopositivity. CONCLUSIONS: In our series, MG and HT occurred simultaneously, or one of them was diagnosed before the other, raising some new questions regarding the immune mechanism of these two autoimmune diseases. Due to the heterogeneous morphological changes of the thymus that we found in this study, we can hypothesize that thymus is involved in the pathogenic mechanism of MG with anti-AChR-antibodies and concomitant HT development.

Clinical and immunohistopathological study of conjunctival melanocytic lesions in pediatric and adolescent patients. A case series.

BACKGROUND: Conjunctival pigmented neoplasia can be benign, premalignant or malignant tumors. Our study aims to establish the epidemiological, gross morphological and immunohistopathological features of the conjunctival pigmented lesions in pediatric and adolescent patients (<18 years), to establish an accurate diagnosis. PATIENTS, MATERIAL AND METHODS: This is a retrospective case series study conducted within two Ophthalmology Clinics from Iasi, Romania, on seven pediatric and adolescent patients. Using the Clinical Observation Chart and the Pathology Registers over a six-years period (January 2015-December 2021), we noted the patients' demographic data, clinical data, and ophthalmological investigations of the lesion, as well as the type of their treatment. All histological sections stained with Hematoxylin-Eosin (HE) and with five antibodies [pan-cytokeratin (pan-CK) AE1∕AE3, S100 protein, Melan A, human melanoma black 45 (HMB45), and Ki67] were re-examined by four pathologists for each case, to identify the type of the conjunctival lesion and its histological and immunohistochemical features. RESULTS: The mean age of all patients was 10.28 years, and the female∕male ratio was 1.3. Right eye was more often affected (71.42%). 71.42% of cases presented an elevated lesion, 57.14% of cases showed a lightly pigmented lesion, but 14.28% of cases exhibited a pink lesion and this feature described the inflamed juvenile conjunctival nevus. In all cases (100%) the conjunctival pigmented tumor was removed with safety margins. The microscopic examination revealed a compound melanocytic nevus in 57.14% cases, a junctional conjunctival nevus in 14.28% cases, an inflamed juvenile nevus in 14.28% cases, and a conjunctival melanoma arising from a pre-existing nevus in 14.28% cases. In all cases of nevi, the nevoid melanocytes showed strong immunopositivity for Melan A and S100 protein, variable and weak immunopositivity for HMB45, and a mean Ki67 labeling index of 1.71%. Conjunctival melanoma revealed strong immunopositivity of tumor cells for HMB45, Melan A and S100 protein, and a Ki67 labeling index of 20%. In all cases, the conjunctival epithelium showed strong immunopositivity for pan-CK AE1∕AE3. All our cases (100%) had a favorable outcome after the surgical removal of the tumor. CONCLUSIONS: Any excision of a conjunctival pigmented lesion must be subject to a systematic immunohistopathological examination, and there is a set of antibodies (anti-HMB45 and anti-Ki67) that are useful for differential diagnosis between a conjunctival nevus and a conjunctival melanoma.

Morphological aspects of the vasculogenesis and angiogenesis during prenatal edification of the circle of Willis: a review.

In the literature, there are many articles reporting anatomical variations of circle of Willis (CoW), defined as those changes that lead to the inability of this anastomotic structure to maintain adequate brain flow. Because there is such a wide variation in the configuration of the CoW, its anatomical variations affect the hemodynamics of blood flow, thus contributing to the development of aneurysms or stroke. As such, we consider that a good knowledge of the embryological development of the constituent arteries of the CoW can shed some light on the causes of the appearance of its anatomical variants. Reviewing literature, we will present the embryological development of the constituting arteries of the CoW and will begin with vasculogenesis and angiogenesis of the vascular system as a whole. Then, we will focus on the embryological development of the internal carotid artery (ICA) and its branches because, starting with the embryological day 24, these arteries are the first vessels that begin to develop to provide the necessary blood for the primitive brain. As the hindbrain increases its volume, a larger amount of nutrients is needed. Because a larger amount of blood is required to be provided by the primitive ICAs, there is a need for arterial capacity development and thus the posterior circulation begin to take shape. At this stage, the posterior circulation consists of a plexiform arterial network that receives blood from the carotid artery through the carotid-vertebrobasilar anastomoses. At the 5-8 mm embryonic stage, these anastomoses begin to regress, and the basilar artery and vertebral arteries become independent of the ICA. We are pointing out on the process of regression of these primitive vessels, emphasizing the fact that their persistence represents the starting point for the appearance of anatomic anomalies of the CoW, which are identified in the adult individuals. In this review, we also present and illustrate some developmental abnormalities of the anterior and posterior parts of the CoW.

The Myth of Prometheus in metastatic meningioma to the liver: from craniotomy to hepatectomy.

Metastases from intracranial meningiomas are rare, and among them, meningiomas with hepatic dissemination are extremely rare. Therefore, there are currently no guidelines for staging and treatment of metastatic disease in meningioma, a disease that is a challenge for both the clinician and the pathologist. Our literature review revealed 24 cases of liver metastases originating from intracranial meningiomas. We used them to analyze the pathological patterns of dissemination and to assess the different management strategies available, the most efficient and beneficial being surgery and chemotherapy, especially in the case of meningiomas with hepatic and∕or systemic dissemination.

The discovery of the circle of Willis as a result of using the scientific method in anatomical dissection.

There are numerous articles on the discovery of this arterial polygon, its history being quite long, beginning with the Antiquity and up to the Modern Era. Making an analysis of the primary and secondary sources on this topic, the purpose of this article is to identify the significant moments of the discovery of this arterial polygon, which is an anatomical structure with great importance for neurologists and neurosurgeons. We will present the contributions to this topic from Renaissance and early Modern Era anatomists, such as Andreas Vesalius, Jean Fernel, Gabriel Fallopius, Giulio Cesare Casseri, Adriaan van den Spiegel, Johann Vesling, and Johann Jakob Wepfer von Schaffhausen. We also pointed out that the contribution of the famous British anatomist Sir Thomas Willis (1621-1675) was the most important one. He published De Cerebri Anatome, in 1664, in which he described the vascular arrangement laying at the base of the brain, accompanying it by the exquisite drawings of Christopher Wren. Thus, he demonstrated to the medical world that he had reached the greatest understanding of the structure and function of the circular arterial anastomosis. For this excellent discovery, his followers honored him by giving his name to this arterial circle.

Tumor recurrence in parasagittal and falcine atypical meningiomas invading the superior sagittal sinus.

OBJECTIVE: Parasagittal and falcine meningiomas are still a challenge in terms of surgical resection. Although maximal safe resection is the main therapeutic approach, numerous postoperative complications can still occur depending on the locations of these tumors. Moreover, previous studies have reported that parasagittal meningiomas have a higher recurrence rate than meningiomas with other locations. PATIENTS, MATERIALS AND METHODS: We retrospectively reviewed 21 patients with parasagittal and falcine atypical meningiomas [World Health Organization (WHO) grade II], nine of whom had their superior sagittal sinus (SSS) invaded by the tumor. We reviewed the demographic information, operative notes, pathological reports, and clinical and imagistic follow-up reports of each patient over a 5-year time span. RESULTS: All the patients were surgically treated, and the tumor removal was grade II according to Simpson's grading system in 47.6% and grade III in 19% of the cases. The SSS was invaded in 42.9% of the patients. No immediate mortality or morbidity was revealed by our study. Tumor recurrence/progression documented on postoperative imaging amounted to 14.3% and 19%, 12 and 24 months after surgery, respectively. Furthermore, 36, 48 and 60 months after the surgery, the recurrence rate remained the same, namely in 9.5% of the cases. The recurrence was higher in patients with SSS invasion than in patients with no SSS invasion. The tumor recurrence was slightly more predominant in women, i.e., 6% higher than in the male group. CONCLUSIONS: In our group of patients with parasagittal and falcine meningiomas, we report a 47.6% Simpson II resection rate and 19% Simpson III resection rate associated with a very low complication rate and no immediately postoperative morbidity and mortality, compared to more aggressive techniques. The recurrence of parasagittal meningiomas predominated after grade III and IV Simpson resection and dural sinus invasion was a negative predictive factor for recurrence. Therefore, the surgery of parasagittal and falcine meningiomas is beneficial, both for tumor control, but also for improving neurological outcome. Aggressive meningioma resection should be balanced with the increased neurosurgical risk.
