BACKGROUND The extent of peritumoral brain edema (PTBE) associated with meningiomas is very variable. Many causative factors have been investigated, but the mechanism of PTBE associated with meningioma has been unclear until now. Recently, the cerebral-pial blood supply and vascular endothelial growth factor (VEGF) have been implicated as causative factors(More)
The authors report a case of dural arteriovenous malformation (dAVM) in the anterior fossa that was associated with an occlusion of the unilateral middle cerebral artery with Moyamoya phenomenon. The patient was a 79-year-old man referred to our department with an episode of consciousness disturbance and headache. Computed tomography scan showed(More)
A 68-year-old male presented with choroid plexus carcinoma in the left lateral ventricle manifesting as dysarthria and gait disturbance. Magnetic resonance imaging showed a homogeneously enhanced mass in the trigone of the left lateral ventricle. Selective left posterior cerebral arteriography showed the tumor was fed by the left medial posterior choroidal(More)
A case of cranial hypertrophic pachymeningitis of unknown etiology in a patient with 15-year history of headaches, cranial nerve palsies, and gait disturbance is reported. A 77-year-old woman was brought to our institute in a coma. CT revealed intracerebral hemorrhage in the right temporal lobe and thickening of the falx and tentorium. Fifteen years(More)
Supratentorial hemangioblastoma is encountered very rarely. About 80 cases in all have been reported. The authors present a case of supratentorial hemangioblastoma in the thalamus with gradually enlarging cysts. The patient was a 45-year-old man with complaints of left hemiparesis and headache. Computed tomographic scans of the brain showed a cystic mass(More)
Compression of the crus cerebri against the free edge of the tentorium contralateral to a supratentorial mass, the so-called Kernohan's notch, can be a cause of false localizing sign. Kernohan's notch has been thoroughly studied clinically and pathologically, but not radiographically. The authors describe a case of left chronic subdural hematoma, which(More)
The authors report a case of so-called "infected subdural hematoma" as a complication of chronic subdural hematoma. The patient was a 55-year-old man who had sustained a small laceration of the forehead in a traffic accident on March 29, 1995. No fractures were detected on skull roentgenograms, and general and neurological examinations failed to reveal any(More)
Two cases of bilateral multiple primary lung cancers are presented. One is synchronous, and another is metachronous. Case 1: An abnormal shadow in the left lower lobe was found on the chest radiograph of 40-year-old female during a regular check-up. Chest computed tomography (CT) film showed a micronodule in the right S2. Left lower lobectomy was performed,(More)
We measured the immunoglobulin, beta1 C globulin, beta1E globulin, C3a, and CH50 in 20 patients with anaphylactoid purpura (Schönlein-Henoch purpura). IgA values proved to be elevated in 5 out of 11 cases. beta1 C globulin values were lower in 2 out of 8 cases and fell within the range of normalcy in the remaining 6 cases. beta1 E globulin values were(More)
A 35-year-old women complained exertional dyspnea during medication therapy for pulmonary tuberculosis. Thoracotomy was done under the diagnosis of stenosis of the left main bronchus and of obstruction of the left lower bronchus due to bronchial tuberculosis. The collapsed inferior lobe of the left lung with fibrotic change was resected. The left main(More)
