The case is presented of an intraspinal
meningioma
in a 14-yr-old female. After surgical exploration pulmonary
metastases
became apparent. At necropsy the tumour had increased proportions of the cathodal isoenzymes LDH-4 and 5. This pattern has previously been observed in malignant meningiomas and may be used at the time of biopsy to assess malignancy.

Brain tumors have been tested for their glial fibrillary acidic protein (GFAP) content by means of the rocket electrophoresis technique.
Meningiomas
and neurinomas were low in GFAP.
Metastases
had a low level of GFAP except when contaminated with surrounding tissue. Non-nervous tumors such as myeloma, myeloplaxoma and adenocarcinoma gave negative results. More detailed correlations with histological observations have been looked for in glial tumors. Low levels of GFAP were always associated with signs of malignancy such as mitoses and giant or atypical cells, whereas high levels of GFAP were correlated with the presence of well-preserved astrocytes.

Three cases of histologically verified neurinomas of the oculomotor nerve are reported. The preoperative diagnosis in all three cases was not made; on the contrary all cases were diagnosed as sphenoid ridge meningiomas. The oculomotor neurinoma manifests itself in the beginning with a discrete progressive palsy of the oculomotor nerve leading in later stages to complete ophthalmoplegia. Proceeding the oculomotor nerve paresis or going parallel to it is a functional loss of the homolateral optic nerve sometimes progressing to amaurosis. Unilateral exophthalmos as well as frontal or orbital neuralgic pain with or without sensory disorders in the area of trigeminus-I are characteristic for the clinical picture in later stages, all symptoms characteristic for the syndrome of the apex orbitae, resp. the superior orbital fissure, resp. the anterior cavernous sinus. The differential diagnosis has to consider above all the sphenoid ridge
meningioma
, the trigeminal neurinoma and the numerous tumors within the cavernous sinus (aneurysmas, meningiomas, chondromas,
metastases
of carcinomas, pituitary adenomas etc.) or the middle cranial fossa. Plain X-ray, carotid angiogram and computer tomogram are essential diagnostic means for localization and extension of the tumor but not for histological diagnosis. Oculomotor neurinomas are very seldom. The three observed cases did not have any relation to a possible generalized neurofibromatosis.

Among 400 observations by the authors, 2 per cent were admitted without and another 22 per cent with slight neurological disturbances. An incomplete transverse lesion of the cord with paraplegia was found in 61.7 per cent, a complete paralysis in 14.3 per cent of the cases.
Meningiomas
and neurinomas were found in 60 per cent of the patients. The average age of the tumour patients was 43,8 years.
Meningiomas
and
metastases
show a tendency to occur in older age groups. The "Glioma Age" was around 25 years. The majority of the tumours were located at the level of the thoracic cord. When breaking down according to the kinds of tumours, a different picture is obtained: neurinomas are chiefly located in the region of the cervical medulla and the thoracolumbar region; gliomas are mainly found in the cervical part of the medulla up to the central thoracic cord. A dissociation of the cerebrospinal fluid was found in 90 per cent of the examinations; in 50 per cent of the patients it was above 200 mg%. Within a period of four weeks after the operation, the following results were obtained: 5 per cent free from complaints, improvement in 39 per cent, aggravation in 10 per cent and 46 per cent still uninfluenced.
Meningiomas
and neurinomas showed the highest degree of improvement. 24 per cent of the patients suffered from transitory rectovesical disturbances, 15 per cent from urinary tract infections, 12 per cent from decubitus, 9 per cent from wound healing disturbances and another 9 per cent from pneumonia. Meningitis was found in 2 per cent. Within four weeks post operationem, the death rate was 10.5 per cent, but this was in the phase before the introduction of microsurgery. On the accuracy of the diagnoses: in 18 per cent the neurological findings were in agreement with the diagnosis and in 49 per cent they showed differences of 1 to 3 segments; in 11 per cent no definite diagnosis could be made. In 46 per cent the native X-ray picture showed pathological changes. Myelography with positive contrast media showed positive findings in 97 per cent and 98 per cent of positive findings were obtained with myeloscintigraphy.

This is a review of primary and secondary tumors of the optic nerve. The emphasis is an optic nerve gliomas and meningiomas. Optic nerve gliomas are slowly growing astrocytic neoplasms of the anterior visual pathways, the majority of which occur within the first two decades of life, with equal sex incidence in about 1 of 200,000 patients presenting with eye complaints. The incidence is greater in neurofibromatosis. The typical presentation is visual impairment in a verbal pre-school child with optic canal enlargement and optic atrophy. An intraorbital location of the tumor leads to axial, irreducible, non-pulsatile proptosis. An intracranial location may disturb hypothalamic and pituitary function and produce hydrocephalus. Ocular findings may also include limited motility on a mechanical-restrictive basis, a pupillary relative afferent defect, nystagmus, and variable, non-specific visual field defects. Roentgenographic studies may show concentric unilateral enlargement of the optic canal with preservation of a well corticated margin, a fossa under the anterior clinoid process in continuity with the optic canal ('J'-shaped sella), and findings of increased intracranial pressure. On pathologic examination the tumor is a smooth, fusiform, intradural enlargement of the optic nerve. Histologically there is proliferation of elongated (pilocytic) astrocytes in reticulated patterns with intervening microcystic spaces containing mucosubstance and surrounding reactive hyperplasia of the arachnoid. Mitoses are not found. The diagnosis is clinical X-ray studies and brain scan should be performed. The differential diagnosis is that of unilateral proptosis in a child and includes acute ethmoiditis, hyperthyrobidism, craniostenosis, other neoplasms, Hand-Schuller-Christian disease, and orbital hemorrhage due to trauma. Surgical resection is performed in cases with unilateral optic nerve involvement, the surgical approach being determined by tumor location. Bilateral or chiasmal cases are treated with radiotherapy when progression occurs. Malignant optic nerve gliomas and optic nerve hyperplasia are also discussed. Optic nerve meningiomas arise from the nerve sheath and are to be distinguished from orbital meningiomas arising from ectopic arachnoidal cells or those secondarily involving the orbit by extension from adjacent sites. Up to 80% of orbital meningiomas occur in females, in two age peaks, 25% in the first decade, and the rest in the 5th decade.
Meningiomas
present with visual loss and may produce proptosis, papilledema and/or optic atrophy, retinal striae, opticociliary shunts, limitation of extra-ocular movements, and lid edema, Signs of von Recklinghausen's disease should be sought. X-rays are the mainstay of diagnosis. Orbital meningiomas are composed of cells in sheets or in whorls with some spindle shaped cells. Calcifications are typical. Usually the dura is penetrated and the orbit invaded. Primary orbital meningiomas are locally infiltrating but do not
metastasize
. Complete local excision en bloc is recommended...

A cerebral collision tumor in which a convexity
meningioma
was invaded by a metastatic squamous cell carcinoma of the cervix uteri is described. This is the first time such a lesion has been reported to invade a cerebral
meningioma
. The patient lived three active years postoperatively until the lesion recurred. Her status then deteriorated, and she died five years after the operation. This was a longer follow-up than any among the other 17 cases of carcinomatous
metastases
to meningiomas found in the literature.

The history, clinical course and pathological findings are reported of a patient who developed a recurring, malignant meningioma. Widespread extracranial
metastases
occurred, particularly in the liver. Hypoglycaemia was a prominent feature during the late course of the disease. The influence of the histological type of
meningioma
and the effects of surgical interventions on the development of extracranial
metastases
are discussed together with the relationship of the tumour to hypoglycaemia.

The findings and diagnostic results in 600 examinations of primary and metastatic intracranial neoplasms performed at one hospital with the EMI scanner are presented and the effectiveness of this method is compared with that of radionuclide imaging, cerebral angiography, and pneumoencephalography. The computed scan proved to be highly reliable in the diagnosis of glioma, cerebral
metastases
,
meningioma
, and acoustic neuroma.

A series of 17 meningiomas histologically characterized by a papillary pattern is reported. This pattern was invariably associated with other histologic features of malignancy. The tumors often displayed aggressive clinical behavior marked by a high rate of local recurrence or the development of distant
metastases
. A relatively large proportion occurred in children. It is suggested that this variant of
meningioma
is sufficiently characteristic to justify its separation as a distinct clinicopathologic entity.
