1/128. 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.

2/128. Microvascular reconstruction of the skull base: indications and procedures.

    PURPOSE: The aim of the current study was to review the use of free tissue transfer for reconstruction of the skull base and for coverage of intracranial contents. patients AND methods: From 1990 until 1996, revascularized flaps were transferred to the skull and the skull base in 11 patients in whom intracranial/extracranial resection of tumors of the skull base was performed in cooperation with the Department of neurosurgery. The defects resulted from removal of squamous cell carcinomas (n = 4), basal cell carcinomas (n = 4), malignant melanoma, malignant schwannoma, and malignant meningioma. Defect repair was accomplished by revascularized transfer of latissimus dorsi muscle flaps in seven cases and rectus abdominis flaps and forearm flaps in two cases each. In five patients with extensive intracranial tumor spread, reconstruction was performed for palliative reasons. RESULTS: A safe soft tissue closure of the intracranial and intradural space was achieved in all patients, whereas the contour of the facial skull and the neurocranium was satisfactorily restored at the same time. By using the entire length of the grafted muscle, the vascular pedicle could be positioned next to the external carotid artery and conveniently connected to the cervical vessels. The mean survival time of the patients with palliative treatment was 8.4 months, with an average duration of hospital stay of 24.5 days. CONCLUSIONS: Despite the increased surgical effort of revascularized tissue transfer, microvascular reconstruction of large skull base defects appears to be justified, even as a palliative measure.

3/128. Diffuse calvarial meningioma. Case report and review of the literature.

    An extremely unusual calvarial meningioma in a 77-year-old woman is reported. The meningioma spread widely and symmetrically within the calvaria and grew extracranially within the scalp as well as intracranially. Reactive dural hyperplasia induced narrowing of the intracranial space and occlusion of the superior sagittal sinus, resulting in intracranial hypertension. After external decompression, the patient's symptoms markedly resolved. The authors review the literature on calvarial meningioma, discuss its pathogenesis, and propose mechanisms responsible for the patient's intracranial hypertension.

4/128. Extracranial metastatic meningioma.

    Meningiomas rarely metastasize outside the intracranial compartment. We report a case of disseminated metastases from a recurrent intracranial meningioma and review the imaging and pathological literature on metastatic meningioma.

5/128. Extradural meningioma in the left fronto-temporo-parietal region.

    A case of a 47-year-old male patient who presented with a history of complaints of headache, vertigo and an expanding painful swelling on the left side of the head over the last year is reported. The lump was 15 x 15 cm and protruded 1-3 centimeters. Neurological examination revealed the presence of a mild right hemiparesis with right central facial palsy. Plain skull x-ray film demonstrates a heterogeneous bone thickening in the left fronto-temporo-parietal region with a small osteolytic focus and spotted shadows. Computed tomography scan of the skull showed that a major part of the squamas of the frontal and temporal bones were transformed into spiculoform structures turned outwards and inwards. Thus the bone appeared thickened overall. There were no alterations in the cerebral structures. The tumour was completely removed. It was located extradurally and through the bones extended to the soft tissues under the skin. The histological findings showed a meningioma with hemorrhages and necroses and the presence of lipids containing xanthochromic cells. After a surgical extirpation of the tumour a reduction of the neurological symptomatology and subjective complaints was observed.

6/128. Intradiploic meningioma of the skull. Case report and review of literature.

    A case of a patient with an accidentally discovered scalp mass is presented. Radiological investigation documented an osteolytic intradiploic lesion of the cranial vault. The lesion was surgically removed and histological examination revealed a meningioma. The literature concerning these uncommon tumours of the skull is reviewed, and the differential diagnosis is discussed.

7/128. Fronto-orbitonasal intradiploic meningioma in a child.

    Intradiploic meningioma, which may be classified as a subgroup of intraosseous meningioma, is a rarely encountered disorder. To date, less than 10 cases have been reported. Here, we report a case of fronto-orbitonasal intradiploic meningioma. A 12-year-old female with exophthalmos and diplopia was operated on for a cranial intradiploic mass lesion. Histopathological evaluation of the specimen confirmed the diagnosis of intradiploic psammomatous meningioma. Her exophthalmos did not change, but the diplopia disappeared. This case is unique in that it is an extensive case of intradiploic meningioma of the orbital roof and frontal base in a child. Intradiploic meningiomas generally are of psammomatous type. Especially tumors adjacent to the orbita cause exophthalmos; cases located on the other side of the calvarium may not cause any symptom or sign other than headache or sometimes a mass on the scalp. Treatment, as with meningiomas located in the intracranial cavity, is total resection of the lesion.

8/128. Giant cell tumour of the temporal bone: case report and review of the literature.

    This paper presents an expansile lesion of the temporal bone, in a 14-year-old boy, that was initially diagnosed as intra-osseous meningioma from CT appearance. At histopathology a final diagnosis of giant cell tumour was made. A brief review of the literature is presented for this rare case.

9/128. Intraosseous microcystic meningioma.

    Extradural ectopic meningioma is a rare tumor. We report on an example of microcystic meningioma arising in the skull of an elderly woman. Radiological examination revealed a localized osteolytic lesion in the left parietal bone. At surgery, it was discovered that the tumor was located within the skull without any evidence of extraosseous extension. The light microscopic, immunohistochemical and ultrastructural features were consistent with a microcystic variant of meningioma. To our knowledge, this is the first case of an intraosseous microcystic meningioma, and we believe that this type of meningioma should be considered in the differential diagnoses of myxoid bone tumors of the calvarium.

10/128. Extracorporeal irradiation of tumorous calvaria. Case report.

    This patient with recurrent meningioma grossly involving the frontal bone underwent craniotomy and tumor resection. During the procedure a bone flap was irradiated extracorporeally at a very high dose (120 Gy) sufficient to sterilize residual tumor cells, and the bone was then successfully replaced orthotopically for reconstruction. The use of autologous irradiated bone in this setting offers advantages over cadaveric transplantation and prosthetic implants. radiation might cause less disruption of the bone's architecture than other techniques of tumor cell eradication.
