A giant aneurysmal cerebral arteriovenous malformation in the left parieto-occipital region is described in a 4 year old child, including resolution of the alternating hemiparesis and left ventricular hypertrophy of the heart following successful removal of the malformation by microsurgical technique. This arteriovenous malformation has a large aneurysmal sac, 6x5x4cm, in size with several feeders from branches of the left middle and posterior cerebral arteries and drains directly into the straight sinus. So we have proposed to call it "a giant aneurysmal cerebral arteriovenous malformation".

Two cases of iatrogenically induced false aneurysm of the superficial temporal artery are presented. One patient showed partially filled aneurysmal sac, 1x1 cm sized, on the main trunk of left superficial temporal artery by external carotid artery angiography. Another patient showed aneurysmal dilatation, 3x2 cm sized, of the superficial temporal artery with direct injection of Urograffin into the pulsatile mass. Aneurysm excision is indicated to reduce the risk of hemorrhage from the subsequent head trauma, to relieve headache, and for any cosmetic defect. The authors have reviewed the literature and discussed the incidence, classification, pathogenesis, clinical and angiographic diagnosis, differential diagnosis, and treatment.

OBJECTIVES: The purpose of this study is to review our experience with spontaneous thalamic hemorrhage. Clinical outcome of patients was brought about by comparing stereotactic aspiration and conservative medical therapy. METHODS: The study consists of seventy-three cases with spontaneous thalamic hemorrhage which were treated from the period of Jan. 1993 to Dec. 1999. Thirty-eighty patients were treated with computed tomography (CT) guided stereotactic aspiration and thirty-five patients were treated conservatively. We compared the factors affecting treatment and the factors are as follows: age and sex, conscious level on admission, hematoma volume, hematoma sites, presence of ventricular penetration. RESULTS: The results in the thirty eight stereotactic aspirated cases for the 6 months from oneset are as follows: good recovery or moderate disability in 43%, severe disability in 32%, vegitative state in 11%, dead in 13% respectively. The clinical result was more favorable in stereotactic aspiration, with 11-30cc hematoma volume, extend to internal capsule of hematoma, poor conscious level on admission than conservative medical therapy. But age and sex, conscious level on admission, presence of ventricular penetration were not influential in the statistical outcome between stereotactic aspiration and conservative medical therapy. CONCLUSION: Treatment modality of spontaneous thalamic hemorrhage is still controversial. But stereotactic aspiration is more recommended for improvement therapeutic results than conservative treatment or open craniotomy in case of 11-30cc hematoma volume, extend to internal capsule of hematoma and poor conscious level on admission.

Delayed brain re-expansion is one of the most frequent problems on the chronic subdural hematoma. The aim of this study is to determine the factors affecting brain re-expansion. The study consists of 76 patients with the chronic subdural hematoma treated primarily by simple burr-hole drainage from January 1992 to December 1996. Clinical records and radiologic studies were reviewed retrospectively. The age distribution ranged from 22 to 82 years(mean 64 years), the male-to-female ratio was 1.8:1(49:27). At the 2nd, 4th, 6th and 12th week after surgery, the follow-up study was performed with computed tomography or magnetic resonance image. Complete brain reexpansion was defined as that the subdural space was 5mm or less without midline shift on computed tomography or magnetic resonance image. The factors interfering the brain re-expansion are as follows; d age, low Glasgow Coma Scale(GCS) score on admission, history of chronic alcohol consumption, hypodense hematoma on computed tomography, bilateral hematoma, disappearance of intraoperative brain pulsation, and long duration after trauma. The results of this study may be helpful to predict the brain re-expansion after simple burr-hole drainage. If the complete brain re-expansion is not observed immediately, it should be waited for 6 weeks to conduct the follow-up study. Patient's position and sufficient hydration are important for brain expansion. Further investigations on other factors related to promotion of the brain re-expansion should be followed.

OBJECTIVE: The purpose of the study was to evaluate the clinical and radiological results after discectomy and Lubboc bone graft in the surgical management of the cervical diseases with a new titanium interbody implant and integrated screw fixation(PCB) by anterior approach. METHODS: The authors retrospectively analyzed 28 cases of anterior cervical fusion with PCB system and Lubboc bone(xeno graft) from september 1998 to december 2000. Twenty-eight patients with cervical diseases underwent decompression cervical lesion and followed from 5 to 27 months with a mean follow-up of 14 months. There patients were evaluated with clinically and radiologically at immediate postoperative period and at 3, 6, 9, and 12 months. RESULT: The authors investigated the pre- and postoperative intervertebral disc space, clinical outcomes, radiography fusion rate, and Cobb angle in the fixed segments by anterior approach. The lordotic angles and height of disc space were increased after the operation. The clinical outcome of patients follow-up was good or excellent result based on Odom's criteria with improvement of clinical symptom in about 92.9% of the cervical diseases. Two patients showed loosening of the lower and upper cervical screw of PCB instruments, and two patients showed swallowing difficulty and wound infection. CONCLUSION: The PCB system is a new implant for anterior cervical interbody fusion in the degenerative cervical disease and disc herniations. It provides immediate stability and segment distraction. The results of this study indicate that the PCB system is safe, easy handling of hardware, less complications, high fusion rate, and has provide the keeping the intervertebral disc space height and lordotic angles.

Eosinophilic lung diseases are a heterogeneous group of disorders characterized by eosinophilic pulmonary infiltrates and, commonly peripheral blood eosinophilia. A vast number of drugs have been associated with eosinophilic pneumonia and drug reactions are one of the most commonly reported causes of pulmonary infiltrates with blood and/or alveolar eosinophilia. Nickel exposure may occur in occupations including nickel maker, nickel smelters, stainless steel makers, battery makers, electroformer, electroplater, refining operations etc, and has been associated with an increased risk of lung and nasal cancers. Nickel dust has been reported to induce eosinophilic pneumonia, infrequently. We experienced a case of nickel-induced eosinophilic pneumonia in a 55 years old male patient who has been working at a stainless press factory for 25 years until retirement at January 1998. He complained of dry cough and exertional dyspnea, and presented peripheral eosinophilia and multiple small nodular opacities on chest radiograph. Pathological examination of open lung biopsy revealed diffuse vasculitis involving variable-sized vessels with diffuse infiltration of inflammatory cells, particulary eosinophils. Nickel concentration measured from two dried lung tissue was 39.66 microgram/g and 25.14 microgram/g, respectively.
