Radiographic quality as well as adverse effects of intrathecal metrizamide instillation was prospectively investigated in thirty-three clinical cases admitted to the department of neurosurgery, University of Tokyo Hospital, and Kantoh Teishin Hospital. Metrizamide CT cisternography was performed in fifteen cases using in most cases 10 ml of 170 mg I/ml solution through lumbar route. Eleven cases exhibited "normal" pattern CSF circulation and the remaining four, "delayed" pattern. Eight cases (53%) experienced headache, nausea, and/or vomiting several hours after the instillation. All of these belong to the "normal" pattern group. Four cases of "normal" pattern received electroencephalographic examinations before and after metrizamide instillation. Three revealed appearance of negative spike and slow wave burst or sharp waves one to twenty-four hours after the instillation, along with penetration of metrizamide into brain parenchyma. Diagnostic quality was interpreted as "good" in eleven cases. Small acoustic neurinoma, pituitary adenoma, arachnoid cyst, and subdural hygroma were diagnosed among others. Metrizamide ventriculography was done in four cases. No untoward effect of significance was attributed to metrizamide per se. Cervical myelograpy and/or CT myelography was done in fourteen cases using, in most cases, 10 ml of metrizamide 170 mgI/ml. Polytome tomography with metrizamide instillation through lateral cervical puncture was highly diagnostic, whereas, ordinary X-ray with lumbar instillation yielded less satisfactory results. CT myelography in cases of subarachnoid block required good consideration on instillation site and positioning of the patient. Six cases (50%) among twelve cases where metrizamide had run into the cranial cavity experienced headache, nausea, and/or vomiting to a lesser degree than those of cisterno graphy. Metrizamide is the first contrast agent ever made which can be safely introduced into human subarachnoid space, if administered judiciously, nervous. However, metrizamide is weakly toxic to central system and provokes minor untoward effects as well as electroencephalographic abnormalities and, sometimes, clinical convulsive seizure. It would be wiser to restrict the dosage of metrizamide in cisternographic study, expecially in cases of "normal" pattern CSF circulation, to 1.2 gI or 7 ml of 170 mg I/ml solution. Routine use of X-ray cisternography should thus be discouraged because it needs higher concentration of metrizamide in the intracranial cisterns.

The first symptoms of the disease encountered in 30 patients were paresthesia, constant dull headaches and a feeling of numbness of the face or its half. Eventually weakness, atrophia of the masticatory muscles, a drop or absence of the corneal reflexes and cerebral and focal symptoms super vened (the symptoms depended upon the direction of the neurinoma growth). Signs of hypertension were seen in 17 cases. There was also a protein-cell dissociation: 0.5--7% of protein in pleocytosis 6/3--68/3. The craniograms showed a destruction of the ground of the middle cranial cavity in 24 cases, while in 23 cases there was a destruction of the pyramidal apex. Antiographic studies demonstrated a displacement of the carotid siphon medially (18 cases), forward (8 cases) or behind (5 cases). The tumor vascular network was detected in 5 patients. The diagnosis of neurinomas of Gasser's node requires a comprehensive summarization of the clinical and x-ray findings.

At the UCH in Ibadan, Nigeria, we have seen forty-three patients with verified neoplasms of the brain comprising most histologic types of the glioma/paraglioma series. The astrogliomas formed the largest group, followed by the pinealomas in 16.27% and the medulloblastomas and ependymomas, each occurring in 13.95% of the patients. By the end of the third decade of life 83.7% of these neoplasms have become clinically manifest; the largest number being found in the first decade. Just over half (51.16%) of all the neoplasms and also two-thirds of the patients in whom the masses were found in the posterior fossa were children under 15 years. In nearly all cases the duration of symptomatology on admission to hospital was under 6 months. Headaches, papilloedema and altered states of consciousness were frequent; and the prognosis in general has been poor. The classical glioblastoma multiforme and the acoustic neurinoma are quite uncommon in the Nigerian African; but a fairly full spectrum of the 'gliomas' has been clearly identified in the group of primary brain tumours at Ibadan.

We have reported a case of paratrigeminal epidermoid originated in the Meckel's cave. A 30 years old man was admitted to the department of neurosurgery with chief complaints of continuous right facial pain and numbness of entire right side of the face of three years duration. The positive neurological findings were hypesthesia over the distribution of the right trigeminal nerve, absence of the right corneal reflex and nystagmus on left lateral gaze. Caloric response was absent on the right side, however the audiogram showed normal. Cerebrospinal fluid examination was within normal limit. Electromyography showed giant spike in the right masseter and temporal muscles. Radiogram of the skull revealed a bone-destroying lesion over the medial florr of the right middle fossa involving the apex of the petrous bone (Fig 1). Right carotid angiography showed straightening and forward displacement of C4- C5 portion of the carotid siphon in the lateral view, and vertebral angiography showed displacement of basilar artery to the left side, upward displacement of the right posterior cerebral and superior cerebellar artery in the frontal view (Fig. 2, 3). At the time of operation, an epidermoid was identified in the Meckel's cave and totally removed microsurgically. Small amount of the tumor extending into the posterior fossa was also removed (Fig. 4, 5, 6, 7). Postoperative course was uneventfull except for an episode of headache and high fever of short duration, suggesting the signs of meningial irritation. Two months postoperativelly patient was relived of facial pain and was discharged with sensory impairment of the right trigeminal nerve distribution. Only 11 cases of paratrigeminal epidermoid, including the cases localized in the Meckel's cave have been reported in the past literatures (Table 1). In this paper we have discussed about the symptomatology and clinical data of paratrigeminal epidermoid and compared with those of trigeminal neurinoma, and meningioma originated in the same region. We would like to emphasize that the importance of differentiating the idiopathic trigeminal neuralgia from the paratrigeminal epidermoid, if the initial symptom of this tumor were tic douloureux. The total removal of epidermoid with capsule is essential treatment following the early diagnosis, however the attempt of total removal is sometimes difficult because of the relationship between the origin, size and extension of this kind of tumor to other important brain structures. And if some of the tumor is left behind at the time of operation, cholesterin meningitis is an important complication.

A case is presented of neurilemmoma of the left oculomotor nerve occurring in a 64-year-old hypertensive woman. The incipient tumour produced ptosis, limited inwards rotation of the eyeball, and persistent pupillary dilatation on the left side. The mechanism of this process is discussed, having regard to the interruption of the fibres innervating these structures by the tumour, and considering the mode of occurrence of the ocular and pupillary impairments. The patient also had generalized athero-sclerosis and fusiform aneurysm of the terminal part of the left internal carotid artery. The symptoms of headache, seizure, coma, and temporary right hemiparesis were considered as manifestations of hypertensive encephalopathy unrelated to the tumour.

This report is a case of intracranial neurinoma of the jugular foramen. A 21-year-old woman was admitted to our hospital with complaints of headache, nausea, tinnitus on the left and deafness on the left. The neurological examination revelaed bilateral choked disc, Bruns Cushing nystagmus, hearing disturbance on the left, slight disturbance of vestibular function on the left, diminished gag reflex on the left, curtain sign on the left, loss of taste on the posterior third of the left side of the tongue, and deviation of the tongue to the left on protrusion, accompanied with atrophy and fasciculation on the left. Skull-XP showed the enlargement of the jugular foramen. Pneumoencephalogram showed the enlargement of the fourth ventricle combined with the superior, posterior displacement of it's floor. We confirmed the diagnosis of the jugular foramen neurinoma on the left. By suboccipital craniectomy a walnutsized tumor was disclosed at the jugular foramen. The tumor was encapsuled with smooth, thick capsule and was colored in dark rouge. This tumor was removed totally and the postoperative course was uneventful. The pathological diagnosis was neurinoma. We consider that this tumor originated in the ninth or tenth cranial nerve.

A rare case of subfrontal schwannoma occurred in a 33-year-old male with the chief complaint of headache. Computed tomography demonstrated a low-density mass in the subfrontal region. Magnetic resonance imaging indicated the mass extension into the ethmoidal sinus. The tumor was totally removed via a subfrontal approach. The histological diagnosis was schwannoma. The most likely origin of the tumor is the meningeal branches or anterior ethmoidal nerve.

We report 2 cases of trigeminal neurinoma presenting with spontaneous intratumoral hemorrhage. There are only 2 similar cases reported in the literature. Presenting symptoms were headache, diplopia, disturbed consciousness and trigeminal disturbance with sudden onset. CT scan showed a typical fluid-fluid level within low-density mass in the cerebellopontine angle in one case. On MRI, one case showed a typical fluid-fluid level on T2-weighted image and another one had mixed signal intensities including hyper- and hypointensities on both T1- and T2-weighted images. Histologically, increased vascularity, consisting of dilated and thin-walled vessels presenting telangiectatic or cavernous angiomatous appearances were observed in the specimens in both cases. The size of these tumors was about 3 cm each in diameter. Risk factors for hemorrhage appear to be large tumor size and increased vascularity.

Massive intratumoral or subarachnoid hemorrhage from neurinomas is very rare. The authors report on six patients, four men and two women, with neurinomas that presented as spontaneous intratumoral hemorrhage. The average age of the patients was 56.8 years (range, 31-74 years). Neurinomas originated from the acoustic nerve in four patients and from the trigeminal nerve in two. Four cases were accompanied by the sudden occurrence of clinical symptoms such as headache, double vision, and hemisensory or motor disturbance. The maximum diameter of the tumors ranged from 2.8 to 3.8 cm (average, 3.1 cm). Histological examinations showed massive hemorrhage and increased vascularity, with dilated, thin-walled vessels, in all cases. The size of the tumor and the increase in vascularity with dilated, thin-walled vessels within neurinomas are important pathogenetic factors of hemorrhage. When sudden onset of symptoms or rapid worsening of chronic symptoms occurs in neurinomas, intratumoral or subarachnoid hemorrhage should be considered as a possible cause, and magnetic resonance imaging can be an important tool in obtaining correct diagnosis.

The authors report two cases of neurinomas of the oculomotor nerves: one neurinoma of the oculomotor nerve and one of the abducens nerve. The study of 30 cases in the previous literature points out the major striking features of these tumors. Both headaches and oculo-motor palsies are the most regular clinical features. They are not typically suggestive. Therefore the diagnosis is difficult among all the tumors of cavernous sinus and surrounding structures. C.T. scan and M.R.I. with the clinical history should readily allow pre-operative diagnosis. These data are insufficient to distinguish the affected nerve. The surgical treatment is not always complete due to the tumor infiltration into the cavernous sinus.
