From March 1987 to July 1989, six patients (five dadults and one child) with lung abscess (size, 5-13cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr catheter was inserted for drainage. Five of 6 had a dramatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days (average, 15.5days) in successful cases. One case of the failure in drainage was due to persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provided anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is a safe and effective method for treating patients with lung abscess.

Congentally corrected transposition of the great vessels can best be defined as a malformation in which the aorta and pulmonary artery are transposed in relation to each other but in which the flow of blood is in the physiologic direction. And in addition to the malposition of great vessels, there is an inversion of the ventrice,. Unfortunately this basic malformation seldom exists withot complicating cardiovascular anomalies. We had experienced a case of congenitally corrected transposition of the great vessels associated with itral?insufficiency in 13year-old boy, who presented the most above mentioned findings. We have made diagnosis by cardiac catheterization and selective angiocardiographic study.

Authors observed clinically for congenital anophthalmos in two cases. One case was a boy, aged 6 years, having congenital anophthalmos of right eye with bifid uvula and another case was newbron baby, aged 4 days, having congenital anophthalmos and blepharophimosis of left eye and was born to undernutciented mother from chronic hepatitis.

We present a case of Brown-Sequard syndrome due to a massive cervical disc herniation at C5/6 level, presenting sings of sudden and severe spinal cord compression. The lesion was diagnosed by MRI and herniated cervical disc was removed under the surgical microscope via anterior route. The result of operation was good. A brief review of the literature is given.

PURPOSE: To evaluate the effect of Gd-DTPA on signal intensity of diffusion-weighted magnetic resonance (MR) image and apparent diffuse coefficient (ADC) in dog brain with hyperacute stroke. MATERIALS AND METHODS: Experimental canine model of hyperacute cerebral infarction was made by selective intraarterial embolization with particulate embolic material. Diffusion-weighted MR imaging was performed in five dogs at 1 hour after the embolization of internal carotid artery. After intravenous bolus injection of Gd-DTPA, additional 11 diffusion-weighted MR images were serially obtained from 2 minutes to 90 minutes after injection in each dog. The author evaluated findings of hyperacute cerebral infarction on diffusion-weighted MR imaging, and calculated mean signal intensity and mean ADC in infarcted region and contralateral normal region. Statistical analysis of mean signal intensity, mean ADC and contrast-noise ratio before and after Gd-DTPA injection was performed. RESULTS: Hyperacute cerebral infarction developed in all five dogs on diffusion-weighted MR images obtained 1 hour after embolization. The area of hyperacute infarction had steady increase in signal intensity on diffusion-weighted MR image and decrease in ADC. In normal perfusion area, decrease in signal intensity was observed at 2 minutes the Gd-DTPA injection, whereas ADC did not changed. CONCLUSION: Intravenous injection of Gd-DTPA had no influence on ADC in both hyperacute infarction and normally perfused area, but caused initial transient signal reduction in normally perfused area on diffusion-weighted MR image due to susceptibility effect of Gd-DTPA. It is important to calculate ADC in evaluating the effect of diffusion after injection of Gd-DTPA.

PURPOSE: We evaluated both the patients and the normal volunteers to determine the diagnostic criteria of subacromial impingement syndrome. MATERIALS AND METHODS: We analyzed the radiologic finding of Thirty degree of caudal tilt view (TCTV) and Supraspinatus outlet view (SOV) of 100 shoulders from 85 patients with clinically proved subacromial impingement syndrome and normal 100 shoulders from 60 volunteers. RESULT: In TCTV, the protrusion of acromion below the line of extension from inferior surface of clavicle was shown in 94% of the patient group and 48% in normal group. Sharp tip of acromial protrusion was detectable in 55.3% of the patient group and 10.4% in normal group. In SOV, curved type of acromion was seen in 53% of the normal and 50% in patient group. Hooked type of acromion was detected in 3% and 31% of the normal and patient group, respectively. CONCLUSION: Protrusion of acromion at TCTV itself was not a criteria of subacromial impingement syndrome, but more than 7 mm below the line of extension from inferior surface of clavicle was meanigful. In SOV, hooked type of acromion was a criteria of subacromial impingement syndrome but curved type is was not a finding of diagnostic significence. Acromial spur formation on TCTV and SOV was important criteria of subacromial impingement syndrome.

PURPOSE: To evaluate the clinical characteristics and prognoses of children with functional visual loss. METHODS: Retrospective medical record review was performed in 53 patients 4 to 16 years of age diagnosed with functional visual loss between April 2006 and February 2014. We investigated the clinical features and results of clinical tests and the final status of the patients. RESULTS: Twenty male (37.8%) and 33 female (62.2%) patients were included in the study. The mean age was 9.69 ± 2.76 years. The incidence was highest between 8 to 12 years. The mean best corrected visual acuity at baseline was 0.43 ± 0.23, and 88.7% of patients had mild to moderate visual loss. The symptoms were bilateral in 96.2% of patients, and the difference of corrected visual acuity between two eyes was 1 line or less on Snellen chart in 94.1% of bilateral cases. The symptoms were resolved by 1.8 ± 1.0 months in 59.5% of patients and resolved by the final follow-up visit in 51 (96.2%). However, the symptoms persisted through the final follow-up in 2 patients. CONCLUSIONS: Most children with functional visual loss have bilateral and mild to moderate visual loss. The prognosis of functional visual loss in children was excellent. Most patients recovered from the disease with reassurance supportive care without psychiatric treatment, although a few patients had persistent symptoms.

PURPOSE:We report the results of image-guided percutaneous biopsies with a biopsy gun and evaluate the clinical usefullness. MATERIALS AND METHODS: One hundred and five biopsies under ultrasonographic or fiuoroscopic guidance were performed. Various anatomic sites were targeted (liver;50, chest;22, kidney;12, pancreas;8, intraperitoneum;7, retroperitoneum; ). RESULTS:Obtained tissue was diagnostic in 98 of the 105 biopsies(93%). In each instance, representative core tissue specimens were obtained. Evaluation of the core tissue by pathologist revealed consistent, uniform specimens that contained significant crush artifact in no case. Five biopsies yielded inadeguate tissues which were too small for histopathologic interpretation or were composed of necrotic debris. Two biopsies yielded adequate tissues, but tissues were not of the target. The diagnoses were malignancy in 77 biopsies and benign disease in 21 biopsies. No complications other than mild, localized discomfort were encountered except a transient hemoptysis and pneumothorax which was observed in two patients. CONCLUSION:Cutting biopsy with a biopsy gun provided sufficient amount of target tissue for an accurate diagnosis of malignant and benign disease. It was a safe and useful procedure for percutaneous biopsy.
