Colloid cyst is a relatively rare benign tumor which is usually found in the third ventricle. A patient who had a "colloid cyst" in his right lateral ventricle was experienced. A 33-year-old man had suffered from intermittent attacks of headache and vomiting for five months. On July 22, 1974, he was hospitalized to our clinic because of headache, memory and gait disturbance. At the time of admission his consciousness was clear but he had slight memory disturbance and urinary incontinence. Incipient papilledma was noted and the deep tendon reflexes of the lower extrimities were slightly accentuated. Lumbar puncture revealed a clear CSF and its pressure was within normal limit and the protein was 59 mg/dl. The plain skull films showed no abnormal findings. EEG showed an asymmetry of alpha-wave, and paroxysmal high voltage of slow wave was found in the right frontal area. Right cerebral angiography demonstrated an unrolling of the pericallosal arteries suggesting dilatation of the lateral ventricles. On the 9th hospital day, he suddenly began to complain of severe headache and became drowsy. Mannitol and hydrocortisone were injected intravenously without producing any remarkable effects. A ventricular drainage was done, and the patient recovered rapidly. A conray ventriculography revealed a round filling defect in the right lateral ventricle. A transventricular approach through a short linear incision in the right frontal cortex was preformed on the 25th hospital day. A cyst containing colloid substance, about 5x4 cm in size, was found to be attached to the medial wall of the right lateral ventricle anterior to the foramen of Monro. This cyst was almost completely removed. Histological findings revealed inner lining of epithelial cells, He died on the 25th postoperative day from bacterial meningitis. Autopsy confirmed the cyst to have originated from the right lateral ventricle. A review of the literature was made and the pathogenesis and diagnosis of this disease and the mechanism of development of the symptoms were discussed.

Colloid cysts of the third ventricle are considered as a relatively rate benign tumor, consituting approximately 0.5% of the whole brain tumors, but the surgical cases have rarely been reported in Japan. In this paper, two cases of colloid cyst are reported and the pathogenesis, the importance of the clinical diagnosis and dramatic results after complete extirpation was emphasized. In Case 1, a 29 year-old right handed male, who showed definite symptoms of increased intracranial pressure without lateralizing signs, was diagnosed as colloid cyst of the third ventricle, and operated on with dissecting microscope on April 20, 1973. The colloid cyst was totally removed and postoperatively V-A shunt was performed for adhesive arachnoiditis. Patient did well after surgery and has returned to the previous work. In Case 2, a 41 year-old male, who suffered from sudden onset of severe headache and bouts of frequent vomiting, was admitted to Tokyo Wome's Medical College Hospital on October 11, 1974. Right cerebral angiography revealed findings of increased intracranial pressure and third ventricle tumor was suspected. On October 13, progressively disturbed consciousness occurred. Immediate ventricular tap and continuous ventricular drainage could not regain consciousness and patient expired on October 30. In necropsy, colloid cyst to the third ventricle was found. As far as these are concerned, these cysts might be reasonably said as ventricular epithelial origin in view of the operative and histological findings. Some emphasis was also made in terms of dissecting microscope in removing this tumor, completely preserving the ventricular walls as well as the terminal veins under magnification.

With the introduction of additional diagnostic methods, computerized axial tomography, interventricular tumors are discovered at a time when these lesions are still small and may have presented very insignificant or no clinical symptoms. If the lesion is a benign tumor as a meningioma and within the lateral ventricle of the dominant hemisphere a very difficult problem persents itself to the patient and surgeon. Shall they wait until the tumor reaches such a size to make more permanent symptoms to justify entering the ventricle by the conventional approach through the middle temporal gyrus and leaving the patient at least with a visual field defect? Or should surgery be postponed until the ventricle especially the temporal horne is enlarged due to blockage by the tumor, making the operative procedure technically easier? The authors present a method used in three atrial trigonal meningiomas of the dominant hemisphere which did not result in any neurological deficit which was not present before surgery and which abolished paroxysmal attacks of hemianopsia and severe headaches in one patient. The latter patient was believed to have suffered from migraine for 2 1/2 years.

Osteoid osteoma is an uncommon benign tumor of bone that rarely involves the cranium. If often causes local pain that is worse at night, characteristically relieved by aspirin, and does not correlate with the size of the lesion. The diagnosis depends on skull radiographs and computed tomography. This report describes a case in which radiographs showed nothing abnormal. The diagnosis and operative localization were accomplished with radionuclide bone scanning. Thus, the possibility of radiographically cryptic lesions must be considered in the evaluation of atypical head pain syndromes.

Eight cases of primary mucocele or tumor in the sphenoid sinus treated in our hospital from 1965 to 1988 are reported. Six were male, 2 female. The ages ranged from 18 to 33 years. The course of disease was 20 days to 4 years with an average of 16 months. The common symptoms were headache and serious visual disturbance or involvement of cranial nerves III, IV, V and VI. There were 4 cases of mucocele and 1 case of chondroma, aneurysmal bone cyst, squamous cell carcinoma and chondrosarcoma. All were operated and proven by pathology. The diseases of sphenoid sinus are very difficult to diagnose. In this series, 5 cases had been misdiagnosed. In the early stage, it was often misdiagnosed as retro-bulbar optic neuritis and in the late stage, as malignant tumor of the base of skull or pituitary tumor (4 cases). Sphenoid sinus cyst and benign tumor gave better results. Two patients with malignant tumor died 8 and 9 months of the operation.

Subarachnoid hemorrhage attributable to brain tumor, particularly due to benign tumor, is not common. A case of subependymoma in the lateral ventricle, which manifested itself with an episode of subarachnoid hemorrhage was reported. A 33-year-old woman was admitted to our hospital because of severe headache and transient loss of consciousness, but neurological examination revealed no abnormality except for slight disturbance of consciousness and nuchal rigidity. Lumbar puncture showed an opening pressure over 350mmH2O and grossly bloody CSF. CT scan revealed an enhanced mass occupying the left ventricular trigone. Angiography, however, demonstrated no tumor stain or other vascular abnormality. Preoperative diagnosis was an intraventricular tumor of benign nature. A soft tumor arose from the lateral wall of the trigone was removed subtotally by paramedian parieto-occipital approach. Histology of the tumor was of typical subependymoma with scanty vascularity. Intraventricular or subarachnoid hemorrhage from cerebral neoplasm reported so far, is mostly due to a highly vascularized tumor. Subependymoma is of benign nature with poor vascularity, and therefore, intraventricular hemorrhage from the subependymoma was rarely reported in the literature. On the basis of the findings of angiography, serial CT scans and histological examination, it is reasonable to assume that intraventricular bleeding in our case is not attributed to the tumor per se, but to tearing of subependymal or ependymal veins extremely extended by the tumor growth.

Prolactinoma, a benign tumor originating from the lactotroph cells of the anterior pituitary, is responsible for signs and symptoms related to both hypersecretion of prolactin and tumor mass. Hyperprolactinemia frequently causes menstrual cycle disturbances, galactorrhea and infertility in women, sexual disorders in men. Microadenomas, characterized by a largest diameter less than 10 mm, may induce frontal headaches, and macroadenomas (more than 10 mm in diameter) may also impair visual function through chiasma compression. Treatment modalities include dopamine agonist therapy such as bromocriptine which allows normalization of prolactin levels, restoration of gonadal functions and tumor shrinkage in most cases. In microadenomas a definitive cure may be achieved by transsphenoidal total selective adenomectomy.

Chondromyxoid fibroma is an unusual benign tumor of cartilaginous derivation. We describe a rare example of chondromyxoid fibroma of the frontal-sphenoid junction with orbital infiltration in a 35-year-old Hispanic woman who presented with frontal headaches. Gross total excision was performed. The excised mass was composed of neoplastic cells with chondrocytic features within a myxoid matrix. Bony infiltration was present without infiltration of dura mater or brain tissue. The lack of mitotic activity, low cell density, lack of nuclear pleomorphism, and a fused lobular architectural pattern indicated that the lesion was a chondromyxoid fibroma. The lack of hyaline cartilage helped differentiate the lesion from enchondroma. Our case demonstrates the uncommon occurrence of intracranial chondromyxoid fibroma with orbital infiltration. When faced with an intracranial chondrocytic tumor, it is important to distinguish this neoplasm from enchondroma and chondrosarcoma.

Case report of a 29-year-old woman with an psammomatoid ossifying fibroma of the left frontal sinus. Headache was the presenting clinical symptom. The tumor and its intracranial extension were identified by computed tomography and magnetic resonance tomography. Through a two-step combined neuro-rhinosurgical operation the tumor could be completely removed. Ossifying fibroma is a benign tumor mostly affecting the mandible and maxilla. A more aggressive approach may be more beneficial than expectant observation or curettage in the initial management of this benign neoplasm. Because of the unusual location of this rare entity the case history is published and differential diagnostic and therapeutical implications are discussed.

The imaging features of benign osseous lesions of the bone are often characteristic and suggestive of a specific diagnosis. This is particularly true for skeletal benign bone-forming lesions such as enostosis, osteoma, osteoid osteoma and osteoblastoma. Enostosis or bone island is an incidental finding in the axial skeleton (pelvis, spine, ribs) of asymptomatic patients; it appears as a small (0.2-2 cm) round to oval sclerotic area with irregular, radiating ('thorny') spicules peripherally. Osteoma is a benign slow-growth tumor and usually an incidental finding in cranial sinuses, vault and mandible, and presenting as a homogeneous, sharply defined bone mass arising from bone surface; its signs and symptoms are rare and depend on the tumor size and location--e.g. sinusitis, headache, exophthalmos, diplopia. Osteoid osteoma is a painful highly vascularized benign tumor usually affecting the long bone diaphysis cortex of young patients; it generally appears as a small radiolucent nidus with or without central calcification and surrounding bone sclerosis on radiographs, and as a 'hot' spot on scintigraphy. CT is the method of choice for the definite location of the nidus especially in sites of complex anatomy, such as the spine, pelvis and hindfoot. Osteoblastoma is a rare tumor, histologically similar to osteoid osteoma but with a significantly different clinical potential because of the possibilities of postoperative recurrence, of its locally aggressive behavior or, rarer still, malignant transformation; the spine and long bones are affected in more than half the cases. Its radiologic appearance is not always distinctive and usually characterized by a lytic lesion with varying bone production and expansile behavior; CT and MRI are required for the diagnosis of spinal osteoblastomas. When a bone-producing tumor or tumor-like lesion is suspected but no specific diagnosis can be made, the knowledge of the range of the imaging findings of these lesions will allow a suitably ordered differential diagnosis. Radiography is the single most effective imaging method in this respect. CT is required for the tumors in complex anatomical sites, such as the spine, pelvis and hindfoot, as well as for the optimal assessment of the tumor matrix. MRI is specifically required to study the lesion effect on the spinal canal.
