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.

The incidence of intracranial meningioma in Manitoba, Canada, was reviewed from 1980 through 1987. During that time, 193 tumors were diagnosed, with a male:female ratio of 1:2. This occurrence corresponded to crude incidence rates of 2.3/100,000 for all meningiomas and 0.17/100,000 for malignant meningiomas. Among malignant meningiomas, the male:female ratio was 1:1. The age-specific annual incidence rate increased with age up to the eighth decade where it peaked at 8.4/100,000. The distribution of histopathological subtypes was: 74 meningotheliomatous (38%), 64 transitional (33%), 14 malignant (7%), 14 fibroblastic (7%), seven psammomatous (4%), four angioblastic (2%), and 16 unknown (8%). The diagnosis of malignant meningioma was based on the World Health Organization criteria, with only Grade III and IV tumors included in this subtype. Clinical features did not allow for differentiation of benign from malignant neoplasms. Individuals with malignant tumors were, however, more likely to suffer paresis (50%) and less likely to be without deficit (14%) than their benign counterparts. The radiographic appearance of "mushrooming" was observed only in patients with malignant meningioma. All malignant tumors showed evidence of peritumoral edema; however, none exhibited calcification. During the 8-year study interval, the tumor recurred in 10 (71%) of the 14 patients with malignant meningioma. Tumor recurrence was accompanied by dedifferentiation from a more benign histology in four patients (2% of the total material).

Twenty-seven cases of chronic isolated abduction deficit, seen in 25 years of neuro-ophthalmology consultation, were reviewed. "Isolated" was defined as the lack of any other neurologic or ophthalmologic findings for at least six months. Cases were further subdivided into the categories of true and pseudo-abducens paresis. The origin, diagnosis, and management of long-standing abducens palsies were determined. Cases of pontine glioma, chordoma, chondrosarcoma, and meningioma that presented as an isolated abducens palsy and remained undiagnosed for at least six months were reviewed.

A case of anaplastic astrocytoma associated with pituitary adenoma is reported. The patient was a 33-year-old male, who was admitted with complaints of sensory aphasia, slight left motor paresis, and visual field defects. Neurological examination disclosed sensory and motor aphasia, Gerstmann's syndrome, slight left motor paresis, right homonymous hemianopsia, and bilateral choked discs. Computed tomography revealed a low density mass lesion with slight enhancement in the left temporal region and a ring-like enhanced mass lesion in the suprasellar region. In MRI, both the left temporal and the suprasellar lesions are depicted as low signal intensity areas in T1 weighted imaging, but as high signal intensity areas in T2 weighted imaging. Craniotomy was performed and both tumors were almost totally removed. The tumor in the left temporal region was diagnosed as anaplastic astrocytoma and the other in the suprasellar region was diagnosed as chromophobe adenoma. Multiple primary intracranial tumors of different cell types are rare. About a hundred cases can be found in medical literature. More than two thirds of them are cases of glioma associated with meningioma, but other combinations of tumors are extremely rare. We now report this case of astrocytoma associated with pituitary adenoma. In the literature, there are only 5 cases of similar combination. It is believed that astrocytoma and pituitary adenoma are histologically different. In three of five reported cases, the tumors were in close proximity to each other, but it is doubtful that their close proximity was related to the fact that they developed concurrently.

Sclerosis of the mastoid portion of the temporal bone is often seen on radiographs of patients who have or have had chronic otitis media. Occasionally lesions are seen that cause sclerosis of the entire temporal bone. The otolaryngologist must be alert to the fact that these findings may signify important pathology beyond that of chronic otitis media and indeed may be indicative of life threatening problems in adjacent or distant areas. In this paper the differential diagnoses of sclerotic lesions of the temporal bone will be discussed. These include fibrous dysplasia, osteopetrosis, meningioma, ossifying fibroma and metastatic lesions to the temporal bone. Three representative cases with sclerotic temporal bones are presented. The first is a patient with a conductive hearing loss secondary to stenosis of the external auditory canal. He was found to have a fibrous dysplasia of the temporal bone. The second case is an elderly male with a draining ear and a facial nerve paresis. He was found to have adenocarcinoma of the prostate gland metastatic to the temporal bone. The third case is that of a woman with a meningioma who demonstrated a sclerotic temporal bone on routine radiographs of the skull.

A 42-year-old male presented with a rare extracranial meningioma manifesting as right facial swelling, facial nerve paresis, and hearing disturbance. Neurological imaging revealed a primarily extra-axial tumor extending from the temporal base to the subcutaneous space in the parietal region, and partially into the intra-axial region of the temporal lobe through the dura mater, with a small intracerebral hematoma and a small mass in the porus acusticus destroying the temporal bone, the floor of the middle fossa, zygomatic arch, and porus acusticus. Malignant meningioma was confirmed by histological examination after subtotal tumor removal via the transzygomatic approach. Subdural fluid accumulation like hematoma occurred 5 days after surgery and malignant cells were found in the fluid drained by skull trephination. Subsequently, radiation therapy with a total dose of 60 Gy was administered. One year later, he complained of head and neck pain with motor and sensory disturbances in the right upper extremity, and then developed tetraparesis. Cervical x-ray films demonstrated a compression fracture of the C3 vertebral bone and radiolucent areas at C2-4 levels, while computed tomography showed the tumor invading the subcutaneous space and compressing the spinal cord. He died of respiratory distress. Autopsy revealed that the tumor originated in the temporal region and had directly extended to the cervical region.

A sporadic case of neurofibromatosis type 2 in a 23-year old woman is described with clinical and neuroimaging (CT or MRI) 4 years follow-up. Together with bilateral acoustic tumours multiple intracranial tumours and solitary orbital meningioma were present, the latter being confirmed surgically and histopathologically. Ocular findings of congenital cataract but lack of other external stigmata of neurofibromatosis completed the clinical picture of the disease. Diagnostic criteria of NF2, difficulties in establishing the optimal management options are described and the importance of evaluating of family members is underlined. Neuroimaging pictures showed tumour expansion over 4 years leading to severe disability with total blindness, deafness, paresis and cerebellar syndrome.

Primary oculomotor nerve synkinesis is almost always caused by an intracavernous meningioma or aneurysm. We treated a patient who had signs of primary oculomotor nerve synkinesis from an unruptured extracavernous aneurysm located at the junction of the internal carotid artery and the posterior communicating artery. The aneurysm was successfully clipped, resulting in some improvement in ocular motility and alignment. Although most aneurysms affecting the subarachnoid portion of the oculomotor nerve cause an acute, painful oculomotor nerve paresis, such aneurysms may rarely produce painless primary oculomotor synkinesis and therefore should be considered in the differential diagnosis of this phenomenon.

Forty-two cats underwent craniotomy for removal of a meningioma between 1985 and 1991. Median duration of clinical signs before examination was 1.25 months. All cats had inappropriate demeanor: 48% were dull and 38% were lethargic. Neurological deficits included impaired vision in 93%, paresis in 83%, and seizures in 19%. Computed tomography (CT) showed solitary masses in 86% and multiple masses in 14%. Intraoperative complications included hemorrhage and difficulty excising deep or adherent masses. Anemia in 13 of 42 cats was the most common immediate postoperative complication. Ten of 42 cats had no improvement or a more severe neurological status after surgery. Eight of 42 cats died immediately after surgery; 6 of these were anemic. Of the cats that survived the immediate postoperative period, evaluation 10 to 14 days after surgery showed that 97% (33 of 34) were alert and 79% (27 of 34) had returned to normal behavior. Neurological deficits, except for vision impairment, had resolved in most cats. The duration of follow-up varied from 1.3 months to 55.1 months. Ten cats developed neurological abnormalities from 1 month to 44.2 months after surgery; of these, 6 had tumor recurrence or new growth confirmed by CT scan or necropsy. Overall survival was 71% at 6 months, 66% at 1 year, and 50% at 2 years. Age of cat and location of tumor did not significantly affect survival (P = .1034 and .1851, respectively). There were too few precise measurements of tumor size to make a valid statistical comparison of the effect of size on survival. Location or presence of multiple tumors did not affect final outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

To evaluate the response of cavernous sinus meningiomas to stereotactic radiosurgery, we reviewed our 54-month experience with 34 patients. All patients underwent radiosurgery with a 201-source cobalt-60 gamma unit. Twenty-eight patients (82%) had previous histological confirmation of a meningioma (1 to 5 cranial base craniotomies per patient); 6 (18%) were treated on the basis of neuroimaging criteria alone. The single-fraction radiation tumor margin dose (10 to 20 Gy) was designed to conform to the irregular tumor volumes in all patients. The maximum radiation dose to the optic nerve or tract was reduced to 9 Gy in 31 patients. No patient had tumor growth (100% tumor control) during the follow-up interval (median, 26 mo). Tumor regression was observed in 56% of patients imaged at an average of 18 months. Eight patients (24%) improved clinically at follow-up examinations. Four patients developed new or worsened cranial nerve deficits during the follow-up interval; two had subsequent full improvement. No patient developed an endocrinopathy or new extraocular muscle paresis. Stereotactic radiosurgery, using multiple isocenter dosimetry facilitated by the gamma unit, is an accurate, safe, and effective technique to prevent the growth of tumors involving the cavernous sinus. Despite the proximity of such tumors to adjacent cranial nerves, complications were rare. The maximum length of hospital stay was 36 hours, and all patients returned to their preoperative employment status within 3 to 5 days.(ABSTRACT TRUNCATED AT 250 WORDS)
