PURPOSE: To evaluate the efficacy of percutaneous catheter drainage of tuberculous abscess associated with tuberculous spondylitis. MATERIALS AND METHODS: In twelve patients (male:female = 1:2; mean age, 37.3 years) tuberculous abscess was diagnosed, and was treated by percutaneous abscess drainage (PAD). All patients had either a psoas or iliopsoas abscess and in two, a paravertebral abscess was also present. Four had bilateral lesions, one, a unilateral lesion, and one, paravertebral abscesses and bilateral psoas. The size of abscesses ranged from4x5x12cm to 6x9x30cm; four were septated and all were lobulated. Using an 8.5-14F catheter, 17 of 18 abscesses were percutaneously drained; Ultrasound guidance was used in 12 cases, and CT guidance in five. RESULTS: The volume of drainage mater ranged from 150 to 1200 cc(mean, 600cc), and the duration of catheter insertion was 6-48 (mean, 17.4) days. In no patient did significant complications arise during or after drainage, and in all cases, follow-up studies using ultrasound, CT or MRI were performed. The duration of follow-up ranged from 3 to 35 (mean,15.4) months; during this time, no recurrence was noted. CONCLUSION: Chemotherapy alone is sufficient for treating a small tuberculous psoas or iliopsoas abscess, but for a large abscess, adjuvant drainage is necessary.

A case of metastatic malignant melanoma of ovary with malignant melanoma of skin is rare. The tumor was discovered 17months following excisional biopsy of left hand for malignant melanoma of the skin. Primary ovarian malignant melanomas are extremely rare and are thought to originate in teratomas. Ovarian melanoma without evidence of residual teratoma must be considered metastatic even in the absence of a previously identifiable cutaneous or mucocutaneous lesion. We had experienced a case of metastatic malignant melanoma of ovary and presented with a brief review of literature.

PURPOSE: To evaluate the portal venous anatomy in the right lobe of the liver, focusing particularly on the location and size of the anterior and posterior segmental branches of the portal vein and the relationship of the right subdiaphragmatic peripheral portal vein to the right hepatic vein. MATERIALS AND METHODS: From June 1995 to December 1995, 100 spiral CT scan which showed no abnormal findings in the hepatic area were retrospectively analysed. Portal dominant phase images were obtained after the administration of contrast media, with a delay of 60-65 seconds (100 - 120ml, 2-3ml/sec injection rate), slice thickness 10 mm and table speed 10mm/sec. On spiral CT scans, we assessed the location and size of the right portal vein and its branches and also observed the relationship of this vein to the right hepatic vein. RESULTS: In all patients, the right portal trunk divided into anterior and posterior branches. The anterior segmental portal vein was located cephalad to the posterior segment in 81 cases (81%), at the same level in 17 (17%), and caudad in two (2%). Its diameter was greater (>2mm)than that of its posterior segment in 33 cases (33%), smaller in three (3%), and similar in 64 (64%). In 95 cases, the right anterior segmetal portal vein which was directed posteriorly, supplied the subdiaphragmatic portion of segment 7. CONCLUSION: In 81% of cases, the position of the anterior segmental portal vein cephalad, and in 64%of cases it was similar in size to the posterior portal vein. In almost all cases, the subdiaphragmatic portion of segment 7 was supplied by the portal vein from segment 8. Therefore, the right hepatic vein is not in all cases an adequate landmark for dividing Couinaud segments 7 and 8 in the subdiaphragmatic portion.

PURPOSE: We wanted to report on the functional results and the presence of axial malalignment after performing minimally invasive plate osteosynthesis in distal femur fractures with metaphyseal comminution. MATERIALS AND METHODS: Between March 2007 and June 2009, fifteen patients with distal femur fractures and metaphyseal comminution were treated with minimally invasive plate osteosynthesis, and they were followed for a mean of 17.0 months (range: 12-40 months). The fractures according to the AO/OTA classification were two cases of 33A and thirteen cases of 33C, and seven cases were open fracture. We analyzed the axial malalignment and functional results according to bone union and Sanders' score. RESULTS: All the fractures were united without a bone graft after a mean of 20.4 weeks (range: 16-26 weeks) after the definitive plate fixation. One case had superficial infection and a stiff knee. The average ROM of the knee was 123.6degrees. The average Sanders' score was 33.0, and the results were five cases of excellent results, eight cases of good results and two cases of fair results. There was axial malalignment such as varus malunion in 3 cases and valgus malunion in 2 cases and the average shortening of the limb length was 7.9 mm (range: 0.3-21.9 mm). CONCLUSION: Minimally invasive plate osteosynthesis in a distal femur fracture with metaphyseal comminution provides satisfactory outcomes. However, this should be approached with caution because of the possibility of axial malalignment.

PURPOSE: Contrast-enhanced 3-D ultrafast MR angiography is a widely accepted MR imaging technique for theevaluation of the carotid artery, aorta, renal artery, mesenteric artery and portal venous system. To esti-mateitsclinical usefulness, single -and double- dose contrast-enhanced 3-D ultrafast pulmonary MR angiography wasassessed after a timing examination was performed. MATERIALS AND METHODS: Twenty volunteers underwentgadolinium-enhanced ultrafast pulmonary MR angiog-raphy( 3-D FISP, TR[msec]/TE[msec]=5.0/2.0, with 25 degrees flipangle). In ten volunteers(single-dose injection group) pulmonary MR angiography was performed after theadminstration of 0.1 mmol/kg(single dose injec-tion group), while the other ten(double-dose injection group) eachreceived, prior to angiography, 0.2 m m o l / kg. In all cases, a timing examination was performed during axialturbo-FLASH imaging(TR/TE/TI=8.5/4.0/100, 1 0 degree flip angle) after injection of the same dose as that used forsubsequent contrast-enhanced pulmonary MR angiography. In both groups, overall image quality, pulmonary arteryvisibility and contrast-to-noise ratio of the pulmonary artery were assessed on the basis of images obtained.RESULTS: With regard to overall image quality, there was no significant statistical difference between the twogroups (P>0.05), and in both, depiction of the central and lobar pulmonary artery was excellent. As regardsdepiction of the segmental artery, the average grading of the single dose injection group was 2.83 +/- 0.32, that ofthe double dose injection group was 2.85 +/-0.3, with no statistical significance(P>0.05). With respect tocon-trast-to-noise ratio of the central, lobar, and segmental arteries, the best results were obtained by thedouble dose injection group(P<0.05). CONCLUSION: Although the contrast-to-noise ratio in the double-dose injectiongroup was better than that in the single-dose group, differences in overall image quality and pulmoanry arterydepiction were not statistically significant. Thus, single-dose, contrast-enhanced 3-D ultrafast pulmonary MRangiography can provide useful images in clinical trials.
