A case of acoustic neurinoma with multiple intratumoral hemorrhages is reported. A 56-year-old male noted sudden hearing reduction in his left ear in October of 1985. The diagnosis of a local physician was sudden deafness. About 10 months later, he had two episodes of severe headache without nausea or vomiting. The patient was hospitalized in October of 1986. Neurological examination cerebellar ataxia. cerebellar ataxia. Plain and enhanced computed tomography revealed only an unremarkable low-density area at the left cerebellopontine angle. In contrast, magnetic resonance imaging (MRI) clearly demonstrated a large (3 x 4 x 5 cm), multicystic tumor in the site. On exposure of the tumor at surgery, most of the cysts were found to be filled with a dark red or xanthochromic fluid. The tumor was completely removed following numerous cyst punctures to decrease its volume. There was no evidence of subarachnoid hemorrhage. Histological examination showed a typical acoustic neurinoma. The cyst wall contained numerous telangiectasia-like lesions. The initial symptom of this patient was sudden hearing loss, which is an atypical manifestation of acoustic neurinoma. The massive intratumoral hemorrhage was thought to be caused by telangiectatic lesions in the cyst wall. MRI clearly demonstrated the hemorrhagic cysts within the tumor, especially in the posterior fossa.

A 52-year-old female was admitted with a chief complaint of progressive gait disturbance over the previous 16 months. Neurological examination revealed impairment of the Vth and VIIIth cranial nerve functions and cerebellar ataxia on the left side. Computed tomography showed a petroclival tumor of 5 x 5 x 4.5 cm. Left carotid angiography disclosed tumor staining fed by branches of the tentorial artery. Also, an anomalous artery branched from the internal carotid artery between the C5 and C6 portions and supplied the region usually fed by the anterior inferior cerebellar artery. The tumor was removed via a combination of transpetrosal-transtentorial and transzygomatic approaches. The anomalous artery was confirmed to course along the Vth cranial nerve, replacing the anterior inferior cerebellar artery. Twenty-seven cases of variant persistent trigeminal artery have been reported in the world literature, including this case. The embryological and clinical features of this anomaly are discussed.

An antineuronal autoantibody has been identified in serum from 14 patients, 8 women and 6 men, with small-cell lung carcinoma (SCLC) and a neurologic disorder. Neurologic symptoms began prior to diagnosis of the SCLC in 12 patients. The dominant neurologic disorder was a subacute sensory neuronopathy (SSN) in eight patients, SSN plus lower motor neuron weakness (2 patients), SSN plus autonomic neuropathy (1 patient), cerebellar ataxia (1 patient), myelopathy (1 patient), and multifocal nervous system disease (encephalomyelitis) in one patient. The presence of the same autoantibody in patients with SSN, encephalomyelitis, and autonomic neuropathy suggests that these diseases are different manifestations of the same nosologic process. With one exception, treatment of the tumor, immunosuppressive drugs, and plasmapheresis did not influence the course of the neurologic illness. The autoantibody was not identified in sera from more than 400 controls subjects, including patients with SSN associated with other tumors, SSN without malignancy, other paraneoplastic syndromes, and SCLC without neurologic symptoms. The autoantibody is a highly specific marker of the paraneoplastic syndromes associated with SCLC and its detection in a patient not known to have cancer should prompt a careful search for SCLC.

The authors report a case of recurrent pituitary adenoma, which changed its endocrinological function from GH producing to non-functioning. A 37-year-old woman was admitted to our hospital complaining of headaches, amenorrhea and acromegalic features. Skull X-rays showed marked ballooning of the sella turcica and mild thickening of the calvarium. X-rays of the hands and feet revealed moderate acromegalic changes. On pneumoventriculography, the tumor elevated the floor of the third ventricle. The serum GH level was 29.3 ng/ml, which did not respond to insulin induced hypoglycemia. Radical removal of the tumor was performed through a right frontal craniotomy. Histologically, it was diagnosed as a pituitary eosinophilic adenoma. Immunostains revealed the presence of many GH positive cells in the adenoma. Since the post-operative GH levels were still high (12-16 ng/ml), irradiation to the sellar region was carried out. The serum GH concentration gradually decreased to the normal level in one year after the irradiation. At that time no sellar tumor could be found on CT scans. The patient had been well for six years until she noticed hearing impairment of her right ear. She was re-admitted about seven years after the first admission because of cerebellar ataxia and hearing loss. CT scans revealed a recurrent tumor extending from the sellar region to the right cerebello-pontine angle. Serum GH levels on admission were within normal range (3-4 ng/ml). The tumor was partially removed by suboccipital craniectomy. Pathologically, the tumor was reported as a pituitary chromophobe adenoma. With immunostains, no GH positive cells could be found in the adenoma.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of cerebellar ganglioglioma is reported. A 22-year-old female was admitted to the Kurume University Hospital on August 19, 1985, suffering from headache, vomiting and gait disturbance. On admission, neurological examination revealed staggering gait and the right cerebellar ataxia showing dysmetria and dysdiadochokinesis. Mild choked disc in the right fundus was also noted. Plain CT scan showed the low-density area involving the right cerebellar hemisphere and the part of the vermis with internal hydrocephalus. Enhanced CT scan showed the high-density area adjacent to the low-density area suggesting a mural nodule. A vertebral angiogram in the arterial phase showed an expansive lesion in the posterior fossa and the tumor stain, which was also visualized in the venous phase. An emergency suboccipital craniectomy was then performed. With opening the tense dura mater, the cyst formation was noted and 30 ml of xanthochromic fluid was then aspirated. A well demarcated mural nodule was noted in the lateral wall of the cyst. The nodule was then extirpated in toto. The hypertrophy of the cerebellar cortex was not observed. Histologically, the tumor was consisted of nerve fiber, glial fiber and neuronal cells. Its architecture was differed distinctly from that of hamartomatous diffuse hypertrophy of the cerebellar cortex (Lhermitte-Duclos' disease). Immunohistochemically, the neuronal cells revealed positive staining for NSE and S-100, and the glial cells displayed positive staining for GFAP, S-100. The authors reviewed previously reported eleven cases of cerebellar ganglioglioma including the present case. These results showed that cerebellar gangliogliomas have some characteristic clinical features among general intracranial gangliogliomas.(ABSTRACT TRUNCATED AT 250 WORDS)

Marked non-communicating hydrocephalus may rarely cause ventricular rupture producing either a dilated cystic cavity (ventricular diverticulum) or communication between ventricle system and subarachnoid space (spontaneous ventriculostomy). Ventricular diverticulum has been believed to be collection of cerebrospinal fluid which escaped beneath the pia mater after rupture of ependymal layers and cerebral parenchyma. We proposed herein to report a case of subtentorial ventricular diverticulum which accompanied with choroid plexus papilloma of the lateral ventricle. A nine year-old girl admitted to our hospital complaining of clumsiness of hands and walking, disability of reading, headache and vomiting. The neurological examination revealed alexia, papilledema, anisocoria, righ hemianopsia, weakness of right upper limb, and cerebellar ataxia. CT brain scan showed a large high density area at the trigone of the left lateral ventricle with non-communicating hydrocephalus and an extra-axial low density area in the posterior fossa. The medial space of the left trigone was especially ballooned and is just shifted above incisura tentoria by the tumor. The intraventricular tumor was totally removed by operation and proved to be benign choroid plexus papilloma microscopically. The subtentorial mass was confirmed to be a cyst contiguous to the medial trigone of the lateral ventricle, namely ventricular diverticulum. Three special features were recognized in this case. The first, this was the first example of ventricular rupture accompanied with tumor in the lateral ventricle reviewing all reports of both ventricular diverticulum and spontaneous ventriculostomy. The second, this ventricular diverticulum was not produced merely by hydrocephalus alone but mainly by direct effects of the tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

Primary Carcinomas of Choroid Plexus are seen rarely. In previous literature there were 37 cases which were reported according to Lewis and Russel-Rubinstein malignancy criterias. In this article, we describe 5 years old boy and 1.5 year old girl who suffered from cerebellar ataxia and intracranial pressure increase syndrome. In case 1, the tumor of the fourth ventricle was diagnosed by brachial angiography and ventriculography. In case 2, the diagnosis was established by CT scan. In case 1, the patient died during the postoperative course. In case 2, the postoperative time was unremarkable. A radiotherapy of 3 000 rads was applied to the posterior fossa. One year later, the patient had only mild ataxia.

A case of neoplastic aneurysm caused by left atrial myxoma is reported. The patient was a 50-year-old woman who has been suffered from occasional vertigo and syncopal attack. She was admitted with a sudden loss of consciousness and cerebellar ataxia on December 1, 1983. Cerebral angiogram revealed multiple aneurysms in the periphery of both middle cerebral arteries and obstruction of the right superior cerebellar artery. Echocardiography displayed a cardiac myxoma in the left atrium. She suddenly died from recurrent cerebral embolism on January 7, 1984. The diagnosis was confirmed by the autopsy. The histopathological examination revealed that the wall of cerebral arteries were destroyed by the tumor cells of myxoma, and it caused cerebral aneurysms. We presented the detail of this case, and discussed about a mechanism and a treatment of neoplastic aneurysms.

A case of intracranial multiple fibrous histiocytom is arising from the dura mater and both lateral ventricles is presented. To the authors' knowledge, this is the ninth case of intracranial fibrous histiocytomas reported in the literature. A 10-year-old girl was admitted with a 6 month history of cerebellar ataxia. Radiological examination including CT scan revealed a large mass in occipito-suboccipital region. On November 1, 1978, subtotal resection of the tumor was performed. Yellowish hard tumor, weighing 195 g had wide attachment to the dura mater, but did not invade the brain tissue. Postoperative CT scan, three months later revealed the other tumors in the left lateral ventricle and in the suprasellar region in addition to the lesion that had been operated on. In the course of hospitalization, the suprasellar tumor enlarged rapidly despite of 60Co radiation therapy, then led her to hypothalamic dysfunction. In January, 1981, she had paraplegia and paresis of the right upper extremity. Spinal lesion at the level of C-5 was presumed, but further examination was not performed because of her poor condition. On February 19, 1981, she expired. Autopsy of the head revealed four independent lesions in both lateral ventricles, the suprasellar region and the residual lesion which had been resected subtotally at the operation, respectively. Entire falx cerebri was invaded continuously by the tumor in occipito-suboccipital area. Microscopically, all tumors were identical in histology and were composed of spindle shaped cells with storiform pattern, foam cells and rare giant cells. Any mitotic figures were not detected. Clinical behavior was aggressive but histological figures suggested fibrous histiocytoma.(ABSTRACT TRUNCATED AT 250 WORDS)

A case, a 18-year-old male, of an endodermal sinus tumor (yolk sac tumor) in the fourth ventricle, was reported. The patient had a month history of headache, vomiting and gait disturbance prior to the hospitalization, when he admitted to our service he was in lethargic condition with left cerebellar ataxia and horizontal nystagmus. Lumbar tap revealed clear CSF under normal pressure of 110 mm H2O with the CSF protein of 432.5 mg/dl and cell count of 147/3. The vertebral angiography demonstrated space occupying lesion in the posterior fossa. Plain CT demonstrated only disappearance of the fourth ventricle and slightly dilated bilateral ventricles and third ventricle. However diffuse high density area around the fourth ventricle was demonstrated and the wall of bilateral anterior horn was slightly enhanced, after injection of contrast media. There was no other abnormal findings around the pineal region. Suboccipital craniectomy was performed and the tumor was totally removed macroscopically. The tumor was situated in th floor of the fourth ventricle and infiltrated into the fourth ventricular wall and th adjacent cerebellar tissue. The tumor was with soft, greyish color and extremely vascular. Histologically the tumor was diagnosed as endodermal sinus tumor according to Teilum's classification. There were stellate cells arranged in a loose with vacuolated network which formed cystic cavities and a complicated network of honeycomb appearance with a system of communicating cavities and channels. Various size of intra- and extracellular PAS-positive hyaline globules were also seen. Glomerular-like structure (Schiller-Duval body) was not observed. Immunoperoxidase study clearly demonstrated the presence of intra- and extracytoplasmic alpha-fetoprotein granules in the tumor tissue. The amount of the serum alpha-fetoprotein, measured by radioimmunoassay, showed 400 ng/ml. After irradiation in the posterior fossa (5000 rad) the patient was discharged. Three months later, follow up CT demonstrated small high density area in the anterior horn of the left lateral ventricle, so he was rehospitalised. Irradiation in the whole brain was again administered. The tumor was very radiosensitive. CT, after 800 rad, demonstrated complete disappearance of the tumor. After irradiation totally (3000 rad), he discharged with left cerebellar ataxia.
