Microsurgical removal of an intraventricular meningioma with ultrasound guidance, and balloon dilation of operative corridors: Case report and technical note

The case of a 26-year-old woman with an intraventricular meningioma presenting with visual symptoms is discussed. Preoperative imaging included magnetic resonance angiography, with a high correlation with conventional angiography. The patient underwent microsurgical removal of the lesion by combined transtemporal and transparietal approaches, with intraoperative ultrasound and balloon dilation of operative corridors. There was postoperative improvement of the visual fields. The operative technique will be discussed and compared with the other methods published.

Neuroendocrine disease

Meningiomas that arise from the dura along the sphenoid wing can occur in globoid or en plaque forms. Radiographically they can be defined as occurring in the medial, middle, or lateral portions of the sphenoid wing. The medial group carries the highest neurologic risk for surgical treatment, while the hyperostosing en plaque type is the most difficult to remove completely because of orbital and bone involvement. This chapter addresses the clinical presentation and surgical treatment of sphenoid wing meningiomas with an emphasis on the most recent results from the literature.

Meningioma—an unusual forehead swelling: a case report

Meningiomas are rarely encountered by head and neck clinicians. This report describes a patient with a meningioma presenting uncommonly as a long-standing forehead mass with minimal symptoms. Investigation identified a large bifrontal meningioma with extra-cranial extension involving the right orbit and forehead. The literature is reviewed with particular reference to extra-cranial meningioma and the case is discussed.

Mast cell-rich convexity meningioma presenting as chronic subdural hematoma: case report and review of the literature

A 47-year-old woman with a convexity meningioma presenting as a chronic subdural hematoma is reported. This case is unique in that the symptoms were cyclical and stereotypic. The tumor contained an unusually high number of mast cells. A possible etiologic role of histamine-related vasodilation and tumoral hemorrhage is explored. The relationship between meningioma and subdural hematoma is discussed, and the literature is reviewed.

Paroxysmal perineal pain resembling tic douloureux, only symptom of a dorsal meningioma

A dorsal spinal meningioma presenting with paroxysmal perineal pain as the only symptom is presented. No other such case has been reported.

Clinical Presentation of Meningioma in the Elderly

To compare presenting manifestations of meningioma in elderly patients with those in younger patients. Retrospective survey. Tertiary care center. All hospitalized adult patients with the primary diagnosis of meningioma over a 5-year period (n = 116). Nine patients with recurrence of a previously resected meningioma were excluded. Fifty-two percent (56/107) of patients were > or = 65 years of age. Presenting symptoms were classified as asymptomatic, focal, non-specific, or both focal and non-specific. Presenting neurologic signs on physical examination were classified as focal, non-focal, or normal. Duration of symptoms was classified as < or = 1 week, 1 week to 1 month, 1 to 6 months, and > 6 months. Older patients presented more commonly with confusion (32% vs 4%) and dystaxia (28% vs 10%) than younger patients and presented less commonly with headache (23% vs 49%) and visual changes (21% vs 43%). While 2% of patients were asymptomatic at presentation, the remainder had symptoms categorized as focal (38%), non-specific (26%), or both (34%). There was no significant difference between older and younger age groups in the proportions of patients having focal symptoms. Duration of symptoms for all patients was categorized as < or = 1 week (15%), 1 week to 1 month (16%), 1 to 6 months (23%), and > 6 months (44%). In general, older patients were diagnosed earlier than younger patients. The presence of focal neurologic signs was not significantly different between older and younger patients. Presenting manifestations of meningioma differ between older and younger adult patients, but focality of symptoms and signs is similar. In this case series, the duration of symptoms prior to diagnosis was shorter in older than in younger patients.

Case report: Unusual computed tomographic appearances of meningioma initially misdiagnosed as an intrinsic tumour

We report a meningioma presenting unusual appearances on computed tomography and discuss their relationship to the histology of the lesion and the role of arteriography in atypical peripheral intracranial lesions

Meningioma in a neonate: Case report

A 10-day-old female with a parasagittal meningioma presenting as a subcutaneous tumor is reported. Meningiomas within the 1st month of life are rare. The clinical and pathological characteristics of congenital meningioma are reviewed

Meningioma presenting at a site of a previously aspirated brain abscess

We report the case of a meningioma which developed in the parieto-occipital lobe at the site where a brain abscess had been aspirated 9 years previously. There was no history of head trauma. To the best of our knowledge this is the first reported case of a meningioma associated and possibly aetiologically related to a previous inflammatory process in the absence of head trauma. The association of chronic inflammation and the subsequent development of a meningioma is discussed.

Concurrent Intradural and Extradural Meningiomas of the Cervical Spine

Abstract A case of an extradural spinal meningioma presenting with a separate intradural meningioma at the same cord level is reported. Review of the English literature on spinal epidural meningiomas reveals a high incidence of concurrent intradural tumors in patients with epidural meningiomas. This leads to the conclusion that the intradural space should be evaluated carefully when an epidural meningioma is encountered.

Concurrent intradural and extradural meningiomas of the cervical spine

A case of an extradural spinal meningioma presenting with a separate intradural meningioma at the same cord level is reported. Review of the English literature on spinal epidural meningiomas reveals a high incidence of concurrent intradural tumors in patients with epidural meningiomas. This leads to the conclusion that the intradural space should be evaluated carefully when an epidural meningioma is encountered.

Angioblastic meningioma presenting as a pain in the temporomandibular joint

A case of angioblastic meningioma is presented where the presenting symptom was severe TMJ pain. Theories based on a “referred pain” mechanism, vascular traction, or both, are discussed and suggested as an explanation.

Intracranial meningiomas in children.

Thirteen cases of intracranial meningioma presenting in childhood were encountered at the Hospital for Sick Children in Toronto over a 51-year period. The clinical features, radiology, operative findings and outcome are reviewed.

Meningioma presenting as recurrent transient cerebral ischemia and intracranial hemorrhage

Intracranial tumors are sometimes known to appear first as apoplexy. This report describes a patient with a meningioma of the falx who experienced acute onset of symptoms due to intracerebral and subarachnoid hemorrhage and following a history of transient ischemic attacks on exertion. The tumor was an angioblastic-meningioma. The probably source of bleeding and the mechanism of transient ischemic episodes provoked by exertion are discussed.

Meningioma presenting as an intraoral mass

The following case report illustrates a rather rare oral lesion, an extracranial meningioma. In the dental office the lesion was seen on a periapical x-ray film as a multilocular radiolucency. The patient, however, could not be convinced of the necessity of biopsy until several years later when clinical expansion of the maxillary buccal plate was noted. Thereafter, clinical, radiographic, and histopathologic examination revealed a diffuse meningioma involving the maxillary sinus, the floor of the nose, and the maxillary gingiva. The patient has since refused complete surgical removal but remains alive and well 8 years after the lesion was first noted.
