Meningiomas are the most common primary nonneuroglial extra-axial neoplasms, which commonly present as spherical or oval masses with a dural attachment. Meningiomas without dural attachment are rare and, according to their locations, are classified into 5 varieties, including intraventricular, deep Sylvain fissure, pineal region, intraparenchymal, or subcortical meningiomas. To the best of our knowledge, intraparenchymal meningioma with cerebriform pattern has never been reported. In this paper, we report a 34-year-old Chinese male patient who presented with paroxysmal headaches and progressive loss of vision for 10 months and blindness for 2 weeks...

BACKGROUND: Primary intraventricular meningiomas (IVMs) make up 0.5%-5% of all intracranial meningiomas and represent one of the most challenging lesions in neurosurgery. METHODS: Between 1990 and 2013, 42 patients (30 female, 12 male; mean age, 43.6 years) underwent resection of their IVM. The removal was performed by a posterior parietal approach in 19 of the 40 lateral ventricle tumors, and 1 third ventricle meningioma. The transcallosal approach was used for 3 meningiomas, and patients with other lesions underwent temporal (7 cases) and temporoparietal approaches (12 patients), respectively...

UNLABELLED: The mediobasal temporal region (MTR) is located near the brain stem and surrounded by the eloquent neurovascular structures. The supracerebellar transtentorial approach (STA) is safe access to the posterior MTR structures, however its use for resection of anterior MTR lesions still remains controversial. The article describes the technique and outcome of surgery for different MTR structures using STA. MATERIAL AND METHODS: The paramedian STA was used in 18 patients (13 females and 5 males) for 7 years...

We present the case of a 14-year-old boy with a giant tumor of the lateral ventricle. The patient was operated upon. Histopathology showed the presence of an atypical meningioma. Postoperative imaging confirmed the complete tumor excision. Meningiomas although frequent in adults are rare in children. Intraventricular meningiomas are exceedingly rare. Complete surgical excision should be the goal of treatment and is usually associated with a favorable outcome.

BACKGROUND: It is extremely rare to see cerebrospinal fluid dissemination of intraventricular meningioma, particularly with the development of acute, progressive brainstem/cerebellar dysfunction with an absence of mass formation in the corresponding anatomical sites. CASE PRESENTATION: An 81-year-old man was admitted because of double vision, right facial nerve palsy and truncal ataxia. Brain magnetic resonance imaging showed normal findings except for a tumor mass in the left lateral ventricle, which had been noted over 6 months previously...

A 20-year-old male patient was admitted to our clinic with a 1-year history of headache. The patient's systemic-neurological examination and laboratory findings were normal. Computed tomography and magnetic resonance imaging were performed. Imaging findings showed calcified intraventricular mass and subependymal and gyral nodular lesions. There was a slight increase in ventricular volume. Surgical treatment was performed. Pathological specimens revealed the diagnosis of rhabdoid meningioma. Leptomeningeal dissemination refers to diffuse seeding of the leptomeninges by tumor metastases...

Meningioma's occurring intraventricular region are rare and these occurring in the fourth ventricle is even rare. Because of the rarity, it is not usually considered as a differential diagnosis in any age group. Clinical features and Imaging is not characteristic, and most of them are thought to be some different tumor. Here, we discuss two cases harboring a primary fourth ventricular meningioma Grade II, which was surgically excised successfully. Total excision was achieved in both cases and as the tumor was firm to soft and vermian splitting was not required...

Background Retraction of the overlying brain can be difficult without causing significant trauma when using traditional brain retractors with blades. These retractors may produce focal pressure and may result in brain contusion or infarction. Tubular retractors offer the advantage of low retracting pressure that is less likely to be traumatic. Low retraction pressure in the tubular retractor is due to the distribution of retraction force in all directions in a larger area. Material and Methods We conducted a retrospective study of 100 patients with deep-seated tumors operated on from January 2010 to December 2014...

We report on a patient who showed ideomotor apraxia due to injury of the superior longitudinal fasciculus following brain tumor and tumor bleeding, which was demonstrated by diffusion tensor tractography (DTT). A 60-yr-old, right-handed male patient underwent removal of brain meningioma and drainage of intraventricular hemorrhage and intracerebral hemorrhage in the left fronto-parietal lobe. At the time of DTT scanning (5 wk after onset), he was able to move the right upper extremity against gravity. The patient exhibited an intact ideational plan for motor performance...

Various intraventricular tumors can present with calcifications; however, the choroid plexus can also have physiological calcifications. This is the first case report of meningiomas located at the bilateral foramen of Monro (FOM), concealed by a grossly calcified choroid plexus, presenting with obstructive hydrocephalus. A 60-year-old woman with disturbed consciousness was admitted by ambulance. Head computed tomography revealed significantly high-density lesions that smoothly extended from the choroid plexus of the lateral ventricles to the third ventricle...

BACKGROUND: Conventional approaches to deep-seated cerebral lesions range from biopsy to transcortical or transcallosal resection. Although the former does not reduce tumor burden, the latter are more invasive and associated with greater potential for irreparable injury to normal brain. Disconnection syndrome, hemiparesis, hemianesthesia, or aphasia is not uncommon after such surgery, especially when lesion is large. By contrast, the transsulcal parafascicular approach uses naturally existing corridors and a tubular retractor to minimize brain injury...

Intracranial meningiomas are tumors arising from the covering cells of the arachnoid layer of the dura mater or from the intraventricular choroid plexus. While mostly benign tumors, they still represent a major challenge to neurosurgeons and other medical disciplines involved in their diagnostic and therapeutic management. Although this review intends to give some state-of-the-art information from the literature, it is mainly based on personal experiences since more than 30 years caring for more than 1500 meningioma patients and point to a few new strategies to further improve on patient outcome...

PURPOSE: We report a rare case of anterolateral meningioma of the foramen magnum (FMM) and high cervical spine presenting both intradural and extradural growth in a 7.5-year-old boy. We also performed a review of the relevant peer-reviewed literature. METHODS: The patient presented with progressive tetraparesis and gait instability. Neuroimaging revealed an anterolateral tumor of the foramen magnum, C1 and C2 cervical spine level. The patient was treated in two stages: During the first operation, the extradural part was resected while the intradural part was removed in a second operation...

Unlike patients with World Health Organization (WHO) grade I meningiomas, which are considered benign, patients with WHO grade III meningiomas have very high mortality rates. The principles underlying tumor progression in meningioma are largely unknown, yet a detailed understanding of these mechanisms will be required for effective management of patients with these high grade lethal tumors. We present a case of an intraventricular meningioma that at first presentation displayed remarkable morphologic heterogeneity-composed of distinct regions independently fulfilling histopathologic criteria for WHO grade I, II, and III designations...
