1/13. occipital lobe meningioma in a patient with multiple chemical sensitivities.BACKGROUND: The concurrent diagnosis of meningioma with increased intracranial pressure has not been reported previously in a patient who meets diagnostic criteria for multiple chemical sensitivities (MCS). methods: A patient who had been evaluated in an occupational medicine practice, and by several other physicians for sensitivity to chemical odors was found to have papilledema and a visual field deficit. The patient met the clinical criteria set forth by Cullen in 1987 for MCS. A magnetic resonance imaging (MRI) scan was performed. RESULTS: The MRI revealed a large occipital lobe meningioma, which was surgically resected. Removal of the meningioma had little effect on the patient's symptoms. She has been unable to return to her job as a custodian. DISCUSSION: The etiology of MCS has been disputed and is currently unresolved. Those who evaluate patients with MCS are reminded that meningiomas and other intracranial mass lesions can affect olfaction, and that patients with MCS can have treatable intracranial abnormalities.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/13. Intraoperative haemorrhage associated with the use of extract of Saw Palmetto herb: a case report and review of literature.The significant increase in the use of alternative medicine in general and the herbal and dietary supplement in particular represents a challenge to the health care professionals. Because of their unregulated use, physicians are encountering increasing numbers of toxicities and untoward events. We report a case of severe intraoperative haemorrhage in a patient who was taking the herb Saw Palmetto. His bleeding time which was prolonged, normalized few days after he stopped the herb. This case should increase the awareness of physicians to such possible complications and encourage them to enquire thoroughly about the use of any dietary supplement in all their patients.- - - - - - - - - - ranking = 2keywords = physician (Clic here for more details about this article) |
3/13. Discovery of thoracic meningioma with cord compression on a screening "total body" computed topography scan.BACKGROUND CONTEXT: The use of "total body" screening computed tomography (CT)scans has increased dramatically, although the procedure is controversial, and its benefit to the patient is unproven. When a screening CT scan of the chest is performed, the major areas of interest are the heart and lungs. However, significant portions of the spinal column are also included in the examination. PURPOSE: To describe a case in which a screening CT scan of the chest revealed clinically important findings within the spinal column. STUDY DESIGN/SETTING: Case report. methods: Summary of clinical course and imaging studies, with literature review. RESULTS: A healthy 72-year-old woman without neurologic symptoms was self-referred for a screening "total body" CT examination. The chest portion of the study showed a calcified meningioma with cord compression at the T4 level. Within 2 months of the examination, the patient developed a progressive thoracic myelopathy and required excision of the tumor. Definitive management of the tumor was delayed because the patient was not referred for neurologic or neurosurgical consultation at the time of diagnosis. CONCLUSIONS: This case illustrates two important points. First, clinically significant pathology within the spinal column may be identified on a screening CT scan of the chest. Such lesions may have major neurologic implications for the patient. Second, because most patients undergo-ing screening radiology examinations do not have a referring physician, it is critically important for the radiologist to make prompt referral to a neurologist or neurosurgeon at the time of diagnosis.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/13. Cervical spine meningioma presenting as otalgia: case report.OBJECTIVE AND IMPORTANCE: Cervical spine meningiomas have not been reported to present as otalgia. It is important to include otalgia in the differential diagnosis and workup, especially when more common causes of ear pain have been excluded. CLINICAL PRESENTATION: A 66-year-old woman presented to her primary care physician with severe ear pain. She underwent routine diagnostic testing and eventually was referred to a neurologist. After conservative management failed, the patient underwent cervical spine magnetic resonance imaging, which revealed a large meningioma encompassing C2-C3. INTERVENTION: The patient underwent a cervical laminectomy with complete resection of the tumor. She experienced immediate postoperative resolution of her symptoms. CONCLUSION: This case illustrates the importance of aggressive evaluation of otalgia when routine diagnostic studies are inconclusive. Cervical meningiomas are associated with significant potential morbidity and should be excluded early in the diagnostic process.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/13. Acute haemorrhage into a microcystic meningioma leading to cerebral herniation.Low-grade (WHO level I) meningiomas are slow-growing, benign tumours typically presenting with unspecific symptoms (e.g. headache), seizures, cranial nerve compression and neuropsychological symptoms determined by location and size of the lesion. Haemorrhagic onset and sequelae are rare, and have been described infrequently. This is a case of a 50-year-old male presenting with signs of tentorial herniation secondary to hyperacute intratumoural haemorrhage (ITH) into a previously undiagnosed meningioma. Emergency surgical decompression and exstirpation of the lesion helped to achieve a favourable outcome. ITH has been described in all including benign intracranial neoplasms. Factors associated with a higher risk for haemorrhage in meningiomas are discussed. Though haemorrhages associated with meningiomas have been reported, ITH into low-grade meningiomas leading to herniation remains a rarity. Bearers of known lesions and their treating physicians who opt for conservative or delayed treatment should be aware of this remote complication.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
6/13. blepharospasm-oromandibular dystonia associated with a left cerebellopontine angle meningioma.blepharospasm-oromandibular dystonia is characterized by the presence of spasms of the orbicularis oculi (blepharospasm) and of the lower facial or oromandibular muscles. A patient with this syndrome is presented in which a left cerebellopontine angle meningioma appeared to act as a triggering mechanism for the development of this disorder. On the basis of this report, we recommend that physicians search for this tumor in patients with this disorder.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
7/13. lower extremity manifestations of a meningioma.physicians have long recognized that systemic diseases manifest themselves in the foot. The podiatric physician can play a crucial role in the identification of such pathologic processes. Consultation with various subspecialties, along with sensory, motor and neurologic examinations often are paramount. This article will present a case of a meningioma identified by careful podiatric evaluation and consultation with internal medicine, neurology, and neurosurgery.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
8/13. gadolinium-DTPA enhancement of an optic nerve and chiasmal meningioma.The advent of gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA), a magnetic resonance imaging (MRI) contrast agent, has significantly improved MRI's diagnostic accuracy by enabling the physician to separate magnetically similar but histologically different tissues. A patient with optic nerve meningioma, whose tumor was clearly demonstrated on Gd-DTPA-enhanced MRI but did not appear on noncontrast MRI, is described. The usefulness of contrast agents in MRI diagnosis of neuro-ophthalmologic disorders and ophthalmic tumors is emphasized through this case report.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
9/13. Spinal cord meningiomas in the elderly.The clinical features of six women with spinal cord meningioma are presented. These cases comprise the neurosurgical experience of one of the authors (B.B.) over approximately a 3-year period. Median age was 76 years with a range of 65-89 years. Previous reports of this disorder have not emphasized the occurrence of this tumour in the later decades. A notable feature was delay in diagnosis. Only one patient had a correct diagnosis of spinal cord compression prior to admission. Incorrect diagnoses included diabetes mellitus, osteoarthritis, degenerative spinal disease, gait disturbance secondary to fall and a thalamic cerebrovascular accident. gait disorders at presentation included paraparesis, wide-based gait and unclassified disability. All patients had pyramidal tract signs and five had a truncal sensory level. Plain radiographs of the spine were unhelpful and can dissuade the physician from the diagnosis. All tumours were in the thoracic region. Surgery resulted in cure in all patients and diverted one patient from planned institutional care. Spinal cord meningioma should be considered in elderly patients presenting with gait disorder.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
10/13. Intra and extracranial meningiomas involving the temporal bone.Meningiomas involving the temporal bone are very rare. Until 1964, only 39 cases had been reported in the world literature. Most series reported are very small and a physician is unable, based on his own experience, to acquire a sufficient knowledge about this entity and may raise serious doubts regarding the diagnosis and management of these tumors. In the past nine years the author has encountered five cases of meningiomas involving the temporal bone. This became a stimulus for a thorough research of the world literature of meningiomas in general, with emphasis on temporal bone involvement. Nine more cases were collected from cooperative physicians with whom the author has been associated. These 14 cases are the clinical material analysed in this study. This thesis is divided into three sections: 1. Exhaustive review of the world literature on meningiomas with emphasis on involvement of the temporal bone. 2. A detailed presentation and discussion of the clinical material stressing the importance of the newer diagnostic methods available and the most modern microsurgical techniques used in otological and neurological surgery procedures, applied to the treatment of those lesions. A light microscopic histopathological study of all cases reported is presented. Electronmicroscopy demonstrates the true intracellular nature of an atypical, recurrent meningioma occurring in a child. 3. A critical evaluation of the cases presented and the value of the diagnostic and therapeutic methods applied in this series of patients are here analysed. Conclusions are then drawn based on the experience and knowledge accumulated in this study. The histopathological diagnosis of meningiomas sometimes is difficult. Probably those tumors involve the temporal bone more commonly than has been reported in the literature. Some of these lesions probably are being misdiagnosed as chemodectomas or other neoplasias. Computerized axial tomography, particularly applied to the diagnosis of brain lesions, is the major break-through of recent modern medicine. A noninvasive technique, when used with contrast enhancement, offers great diagnostic possibilities. early diagnosis of meningiomas and their complete surgical excision are the key factors necessary for a successful result with a good prognosis and a low recurrence rate. Although these tumors are classically considered radioresistant, radiotherapy may play a role in the treatment of incompletely excised lesions or in patients of a poor surgical risk. Further experiences and time will probably lead to more definite conclusions regarding the role of radiation therapy or the combined surgical and postoperative radiation treatment. Of all brain tumors, meningiomas offer the best prognosis.- - - - - - - - - - ranking = 2keywords = physician (Clic here for more details about this article) |
