[Ossifying fibroma of the cranial vault. Case report].

A 68-year-old female was admitted with mild headache in the right frontal region. Physical and neurological findings were normal. Plain X-rays revealed a poorly circumscribed, osteoblastic lesion in the right frontal bone. Computed tomography scan showed that the diploic space was destroyed but that the inner and outer tables were intact. On 99mTc bone scan, a hot lesion was visible in the same region. The lesion was expressed as a low-signal intensity area on T1-weighted magnetic resonance (MR) image and as a high-signal intensity area on T2-weighted MR image. The tumor was broadly resected together with peripheral normal bone, and cranioplasty using a resin plate was performed. The tumor was mainly composed of mature, regularly aligned bone (lamellar bone) and intermingled fibrous tissue. Ossifying fibroma is a rare, benign fibro-osseous tumor that mainly involves the craniofacial bone. A few cases involving the cranial vault alone have been reported. The relevant literature is reviewed, and discussion focuses on the differential diagnosis between ossifying fibroma and monostotic fibrous dysplasia.

[A case of Cogan's syndrome associated with multiple cranial neuropathy].

A 52-year-old woman was admitted to our hospital because of disturbance of right visual acuity and double vision. At 38-year-old she became deaf bilaterally and experienced many vertigo attacks. She was diagnosed as Ménière disease. At 45-year-old vertigo attacks disappeared. At 47-year-old right peripheral facial nerve palsy developed transiently with interstitial keratitis and episcleritis of the both eyes. Oral adrenocorticosteroid therapy produced an improvement of interstitial keratitis and episcleritis. On admission, ophthalmological examination revealed bilateral interstitial keratitis and episcleritis, right retrobulbar optic neuritis and she was proven to have bilateral sensorineural deafness by otologist. Neurological examination revealed right abducens nerve paresis. Laboratory examinations revealed slightly increased erythrocyte sedimentation rate. CRP was positive. Serological tests for syphilis were negative. CSF showed mildly elevated protein level. Orbital CT scans revealed the swelling of right optic nerve. Cerebral MRI showed multiple high spotty areas in left thalamus, bilateral basal ganglia and deep white matter in T2 weighted images. After treatment with adrenocorticosteroid, right optic neuritis and abducens nerve paresis improved together with bilateral interstitial keratitis and episcleritis. Multiple cranial neuropathy may develop with Cogan's syndrome.

[A case of senile onset rimmed vacuole myopathy with proximally dominant involvement].

A 73-year-old woman with progressive proximal-dominant muscular atrophy and weakness was described. She had been well until 70-year-old, when she found difficulty in standing up from sitting position. At age 72 years, she could not raise her arms. Neurological examination showed muscular wasting and weakness in the proximal parts of extremities, shoulder and pelvic girdle. In the thigh, the flexors and adductors were severely affected. Muscular weakness was also observed in m. tibialis anterior. Serum CK and aldolase were normal. Electromyography showed low voltage short duration motor unit potentials with positive sharp waves and fibrillations. Rimmed vacuoles were observed in 4.8% of muscle fibers in biopsy sample obtained from right m. quadriceps femoris. No inflammatory cells, PAS-positive materials and inclusion bodies were observed in the sample. This case differs from distal myopathy with rimmed vacuoles, because the onset was very late and her muscular weakness and atrophy was proximal dominant. This case also differs from inclusion body myositis, because muscle biopsy revealed no inflammatory cells or inclusion body.

[A case of reflex epilepsy with binasal visual field defects attack induced by family computer game].

A 12-year-old male case of reflex epilepsy with visual field defects attack induced by a family computer game was reported. This patient showed binasal visual field defects attack when he was playing a family computer game. Neurological findings and ophthalmological examinations were normal. EEG showed spike and slow wave complex distributed on right occipital region. These paroxysmal waves were activated by checkerboard pattern reversal stimuli. Stimulus intensity was closely related with these activations, but not stimulus ratio was. Examinations of brain CT and brain MRI were normal. This patient complained of discomfort without visual symptoms when he suffered checkerboard pattern stimuli. A family computer game needs mental concentration, recognition, decision, alert state of consciousness and complex finger movement. Integration of these factors may have induced visual field defects attack. It is interesting that a family computer game is the inducer of reflex epilepsy with visual symptoms. The number of reflex epilepsy is thought to increase because of prevalence of family computer games.

[Clinical experience of omental pedicle flap for bronchopleural fistula].

We present two patients who underwent the omental pedicle flap method for bronchopleural fistula. The first case was a 61-year-old man who developed empyema with bronchial fistula due to recurrent tuberculosis resisted to chemotherapy. He underwent complete muscle and omental flap closure of empyema space. The second case was a 63-year-old man who underwent pneumonectomy for adenocarcinoma of the lung. About two weeks after the operation, a bronchopleural fistula developed at the bronchial stump. He underwent complete omental flap closure of fistula. They are doing well 18 and 9 months following operation, respectively. The omental pedicle flap method is clinically useful as a closure method for bronchopleural fistula because of excellent blood supply of the omentum.

[A case of Raeder's syndrome caused by metastatic malignant lymphoma].

A case of Raeder's syndrome caused by metastatic malignant lymphoma was reported. The patient was 67-year-old male. He had complained of diplopia, ptosis and frontal headache at the left side. Neurological examinations revealed left incomplete Horner's syndrome (miosis and ptosis, but normal facial sweating) and left abducens palsy, which was considered to be Raeder's syndrome Group 1 (Boniuk and Schlazinger's classification). CT scan, MRI and angiography demonstrated a mass lesion in the left cavernous sinus extending to the sphenoparietal sinus, and a mass lesion in the anterior part of the superior sagittal sinus. During his hospitalization, enlargement of the left cervical lymph nodes was noticed. "Malignant lymphoma (non-Hodgkin)" was diagnosed on the basis of biopsy. Group 1 of Raeder's syndrome is rare, but it is important to define the site of lesion, which is located around the paratrigeminal region at the middle cranial fossa. Because these lesions are very small and metastatic in many cases, various neuroradiological investigations, especially MRI, are necessary for early diagnosis and early treatment.

Idiopathic thoraco-lumbar spinal epidural hematoma. Case report and review of literature.

The authors report a case of a 71-year-old man, who had thoracic pain, flaccid paraplegia, sensory loss below the level of Th10, and disturbance of the sphincter control. CT myelography disclosed an isodensity epidural mass lesion from Th10 to L2, which compressed the spinal cord ventrolaterally. Laminectomy was immediately performed and an epidural hematoma was verified. The literatures of spinal epidural hematoma located in the thoraco-lumber region were reviewed.

[A study on transference of cefmenoxime into the cerebrospinal fluid].

Two grams of cefmenoxime (CMX) was administered by one-shot intravenous injection to the patients in normal pressure hydrocephalus without meningitis, and the transference of CMX into the cerebrospinal fluid (CSF) from blood was investigated. After the injection of CMX, CSF and serum were serially taken, and the concentrations of CMX were measured by agar-well method using E. coli. The conclusions drawn from this study are summarized as follows: The concentrations of CMX in CSF were more slowly decreased than those in serum. The mean ratio of transference of CMX into CSF from the serum was 1.4%. After the intravenous injection of 2 g CMX, the mean maximum concentration of CMX in CSF was 0.36 microgram/ml, which exceeded 80% MIC (minimal inhibitory concentration) against several Gram-positive cocci and Gram-negative rods, and higher concentrations than the 80% MIC were kept over 4 hours in CSF. The efficacy of CMX may be kept by its injections less than 4 times a day.

[A computed tomography study of myotonic dystrophy].

Mental symptom is one of the characteristic features in myotonic dystrophy, but documentation of mental signs including pathological changes of the brain has been imprecise. An attempt to show the involvement of the central nervous system by CT scan and EEG has been done in our department. The material consists of 14 patients 10 males and 4 females, from 15 to 50 years of age. CT scan of the 14 patients showed diffuse enlargement of lateral and third ventricles without definite atrophy of cerebral cortex and brainstem. Measurements of various parts of the ventricles showed a difference and an increase with age of values compared with that obtained from 49 neurologically normal persons (P less than 0.01). Main findings of EEG taken from 7 patients were slowing and low voltage of background activity, and 4 patients showed monotonous alpha waves. Both asymmetry and paroxysmal waves were not found. There was no significant correlation between the degree of ventricular enlargement and the frequency of the alpha activity (P greater than 0.05). Our study reveals that the ventricular enlargement is more correlated with aging than the severity of muscle involvement or the degree of mental deterioration. This fact possibly reflects a progressive nature of the pathology of the brain, especially the white matter.
