1/2332. Transient paralytic attacks of obscure nature: the question of non-convulsive seizure paralysis.

    Eleven patients with transient paralytic attacks of obscure nature are described. paralysis could involve face or leg alone, face and hand, or face, arm and leg. The duration varied from two minutes to one day. Four patients had brain tumors, six probably had brain infarcts, and one a degenerative process. The differential diagnosis included TIAs, migraine accompaniments, and seizures. In the absence of good evidence for the first two, the cases are discussed from the standpoint of possibly representing nonconvulsive seizure paralysis (ictal paralysis, inhibitory seizure paralysis or somatic inhibitory seizure). Because of the difficulty in defining seizures as well as TIAs and migraine in their atypical variations, a firm conclusion concerning the mechanisms of the spells was not attained. Two cases of the hypertensive amaurosis-seizure syndrome have been added as further examples of ictal deficits. ( info)

2/2332. Juxtaorbital en plaque meningiomas. Report of four cases and review of literature.

    Juxtaorbital spheroid wing or ridge meningiomas are the most common of the basal meningiomas. These are at times meningiomas en plaque, which in most patients do not have significant intracranial component. This article reviews the literature on en-plaque meningiomas and discusses the role of MR imaging and CT in the diagnosis of en-plaque meningiomas of the paraorbital region. The role of fat-suppression, gadolinium-enhanced, T1-weighted MR imaging is emphasized. ( info)

3/2332. meningioma of the cavernous sinus in a child.

    Intracranial meningiomas in children are rare, representing 1-4.2% of central nervous system tumors and 1.5-1.8% of all intracranial meningiomas. Meningiomas arising from the lateral wall of the cavernous sinus account for less than 1% of all intracranial meningiomas. To our knowledge, only one case of a meningioma arising from the cavernous sinus has been reported in childhood. A 6-year-old boy presented with left ophthalmoplegia. A slight drooping of the left eyelid was noted at the age of 1 year. magnetic resonance imaging (MRI) with contrast administration revealed an enhancing mass lesion located in the left cavernous sinus. The tumor, arising from the lateral wall of the cavernous sinus, was totally removed and the oculomotor nerve was reconstructed with a sural nerve graft. MRI displayed total tumor removal 1 month after the surgery. The pathological diagnosis was of a psammomatous meningioma. ( info)

4/2332. Intracranial Castleman's disease of solitary form. Case report.

    This 62-year-old woman presented with clumsiness in her right hand. magnetic resonance imaging demonstrated a small lesion mimicking a meningioma, which had arisen from the tentorium and contained notable edema. Full recovery was achieved by total removal of the lesion, which was diagnosed as a lymphoid mass resembling giant lymph node hyperplasia on histological examination. The lack of notable findings on whole-body and laboratory studies was compatible with a rare case of intracranial Castleman's disease of solitary form. The authors document clinical, neuroradiological, and pathological features of this rare disease. ( info)

5/2332. foramen magnum meningioma presenting as amyotrophic lateral sclerosis.

    amyotrophic lateral sclerosis (ALS) is a progressive, degenerative disease of the nervous system. It affects adults in all age groups and leads to death few years after the diagnosis. The etiology is unknown, and there no convincing medical or surgical therapy Some diseases can mimic ALS. If diagnosed early these may be treatable, but if misdiagnosed as ALS and left untreated they may be fatal. We present a case of foramen magnum meningioma presenting clinically as ALS. After surgery, the symptoms disappeared and the neurological deficits improved. ( info)

6/2332. Ectopic dural osteolytic meningiomas.

    Intracranial meningiomas usually originate from the arachnoidal cells of the internal dural layer: meningiomas that originate from different sites are ectopic. The authors describe the case of a small meningioma adhering to the external dural layer without involvement of the internal layer, accompanied by osteolysis of the internal surface of the skull. A review of the literature on cranial ectopic meningiomas yielded only four cases described as originating from the external dural layer. osteolysis of the skull was always present and was not found to have prognostic significance. The authors suggest that these four primary ectopic meningiomas originating from the external dural layer should be differentiated from intraosseous meningiomas of the skull. ( info)

7/2332. Fine needle aspiration (FNA) biopsy of primary cutaneous meningioma: report of two cases.

    Two cases of primary cutaneous meningioma are described. A male and a female patient, aged 56 and 61 years, respectively, presented each with a solitary subepidermal nodule. The initial diagnosis was established in both patients by application of FNA biopsy. The subsequent histologic examination confirmed the cytologic diagnosis. Extensive investigation of the patients by computed tomography (CT) and nuclear magnetic resonance imaging (MRI) scans failed to reveal any primary meningioma of the neuraxis. neurologic examination and routine laboratory test results were all normal. The microscopic features, immunocytological study and histology, which all gave a similar pattern to that seen in intracranial meningiomas, are discussed. Distinction from other cutaneous lesions that may be considered in the differential diagnosis is made. A brief review of the literature is also presented. ( info)

8/2332. Non-surgical treatment of meningioma: a case report and review.

    A woman initially presented with a right hemiparesis and subsequently underwent subtotal resection of a left parietal meningioma arising from the lateral wall of the sagittal sinus. She again presented 18 months after surgery with a hemiparesis and repeat MRI showed tumour spreading into the sagittal and the transverse sinuses. She had a therapeutic abortion at 8 weeks gestation 3 weeks prior to her representation. gestrinone, a synthetic steroid and an antiprogesterone was commenced. Two months later she stopped her medication and is asymptomatic at 16 months. A follow-up MRI revealed that the tumour had shrunk dramatically. This case is the first of its kind with tumour size reduction to less than 20%. We feel that the future of meningioma treatment will be multi-disciplinary and non-surgical options should be considered. ( info)

9/2332. aneurysm occurring within a meningioma: case report.

    Aneurysms can be expected to be found in approximately 0.5% of patients with brain tumours; nevertheless, the real incidence is difficult to assess because angiography is now seldom performed for brain tumours. In the literature, 42 cases of meningioma associated with aneurysms are reported, but in none was the aneurysm intratumoural. We describe a case of intracranial meningioma with an intratumoural aneurysm in a 48-year-old woman. ( info)

10/2332. Stereotactic radiosurgery for anterior foramen magnum meningiomas.

    BACKGROUND: Total microsurgical resection is the procedure of choice for growing and symptomatic foramen magnum meningiomas. We hypothesized that for patients with advanced age, complicating medical conditions, or residual or recurrent meningiomas at the foramen magnum, stereotactic radiosurgery would be a useful adjunctive (n = 2) or alternative (n = 3) treatment. methods: We report our experience in five elderly patients (73-84 years) who underwent gamma knife radiosurgery. The median tumor volume was 10.5 ml and the tumor margin dose varied from 10 to 16 Gy. Because of the irregular tumor volumes along the inferior clivus, multiple isocenters of irradiation were required (range, 2-8; mean 4.4). RESULTS: During the follow-up interval of 1-5 years (median, 3 years), one patient died of an intercurrent illness, and all remaining patients were stable without any further deterioration in their clinical condition. Follow-up imaging studies revealed a reduction in tumor volume in one patient and no further growth in the remaining four. CONCLUSION: We believe that stereotactic radiosurgery provides safe and effective management for patients who are poor candidates for resection of their foramen magnum meningiomas. ( info)
