PURPOSE: To evaluate and compare the diagnostic findings and usefulness of MRI and MR arthrogram in recurrent anterior dislocation of the shoulder. MATERIALS AND METHODS: MRI and MR arthrogram of thirty-two cases of thirty patients with recurrent anterior dislocation of the shoulder were retrospectively analyzed to evaluate glenohumeral ligaments, pattern of labral injury, bony Bankart lesion, capsular stripping, Hill-Sachs lesion, and loose body. RESULTS: Labral abnormalities was detected on MRI in 23 cases(72%) and MR arthrogram in 22 cases(69%) as labral tear, detachment, and deficiency. All cases involved anteroinferior labrum. On MR arthrogram, labral abnormalities was confined to anteroinferior portion in 4 cases(18%), extended into midglenoid level in 13 cases(59%), and that into anterosuperior portion in 5 cases(23%). Capsular stripping was noted on MRI in 6 cases(19%) and MR arthrogram in 12 cases(38%). Loose body was detected only on MR arthrogram in 5 cases (16%). Bony Bankart lesion and Hill-Sachs lesion was detected equally on MRI and MR arthrogram in 2 cases (6%) and 21 cases(66%) respectively. We obtained identical findings on both MR arthrogram and operation field in 6 patients. CONCLUSION: MRI with its excellent soft tissue contrast resolution and multiplanar imaging capafility helps detection of labral injury in recurrent anterior dislocation of the shoulder. MR arthrogram is slightly invasive, but shows good artatomic details of labral-ligamentous-capsular relationship and thus provides accurate detec- tion of pattern of labral injury, capsular stripping, and loose body.

Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as a result of partial or complete obstruction of the bile duct, and may manifest clinically severe from of disease, rapidly deterioration to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying causes were 12 benign diseases(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis (n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients improvement of general condition and failed in three patients. The procedures were preterminated due to the patient's condition in two and biliary-porto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggests that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment.

A case of lacunar skull, female newborn infant, associated with skin defect on the lumbosacral region, spina bifida, meingomyelocele and paraplegia is reported. Hydrocephalus developed eventually. Diagnosis was made by X-ray of skull. The roentgenographic apperance shows typhical a soap bubble texture or irregular patches of rarefaction. A brief review of the related literature is given.

Acute hydrops of the gallbladder is described in one patient who had mucocutaneous lymph node syndrome. During the course of her illness, acute addominal pain, vomiting and right upper guadrant tenderness were developed. Diagnosis was readily made with ultrasonography, and the patient was followed with this te-chnique. We managed her conventionally without surgical intervention. The galbladder returned to normal size within about 3 weeks. Related literatures are briefly reviewed.

We retrospectively evaluated the characteristic computed tomographic (CT) findings in nine patients with exohepatic hepatocellular carcinoma(HCC) pathologically prove by surgery(n=2) or percutaneous needle biopsy(n=7). The CT findings of exohepatic HCC were correlated with clinical findings and compared with those of usual HCC Lesions were in the left lobe lobe(n=7) and right lobe(n=2) of the liver. All lesions showed a well-marginated hypodense mass with capsular enhancement on enhanced CT scan. The patterns of capsular enhancement were complete in five and partial in four cases. The portal vein thrombosis was seen only in one case. There was no difference between exohepatic HCC and usual HCC in clinical findings such as increased α-fetoprotein(α-FP), positive Hepatitis B surface antigen(HBsAg), and underlying liver cirrhosis. In conclusion, the CT findings of exohepatic HCC were a well-defined hypodense mass with complete or partial capsular enhancement and these findings may be useful in differentiation from the tumors of adjacent organs.

PURPOSE: The purpose of this study is to evaluate findings in MRI which maybe useful in differential diagnosis of cervical lymph node enlargement. MATERIALS AND METHODS: We retrospectively analyzed the MRI findings of cervical lymph node enlargement in surgically proven 13 patients. We analyzed the location, size and shape, signal intensity, margin between node and surrounding structures degree and patterns of contrast enhancement RESULTS: No disease specificity in location and size of lymphadenopathy. was demonstrated in MRI. Most lymph nodes shows isointensity or slightly increased signal intensity to adjacent muscle on T1WI and high signal intensity on T2WI. Most of the cases showed contrast enhancement with metastatic lymph nodes showing ring-like and/or patchy enhancement. Tuberculous lymphadenopathy showed homogeneous or rather thick walled ring-like enhancement and one or multiple central nonenhancing portions of eccentrical location in the node. Relatively homogeneous enhancements were noted on reactive lymphold hyperplasia, Lymphoma and Castleman's disease. CONCLUSION: MR imaging was helpful in differentiation of cervical lymph node enlargements. Tuberculous lymphadenopathy showed characteristic findings of rather spherical shaped, thick walled ring enhancement and multiple eccentrically located central nonenhancing portions.

A case of a achondroplasia in a 6 month-old-boy was presented with a brief review of the literature. He was admitted with the chief complaints of frequent respiratory infections, and stunted growth. This baby showed stunted growth, short arms and legs, prominent forehead, flatening of the bridge of the nose, and moderate degree of kyphosis. All laboratory datas were nomal. X-ray showed the thickness of the bones and their irregular epiphyseal ends. The pelvis squared, with flat acetabula and distally decreasing interpedunculate distance of the lumbar vertebrae. 14 month follow up study makes it possible to diagnosis as achodroplsia.

BACKGROUND/AIMS: DA-9701 is a newly developed drug made from the vegetal extracts of Pharbitidis semen and Corydalis tuber. The aim of this study was to evaluate the effect of DA-9701 on colorectal distension (CRD)-induced visceral hypersensitivity in a rat model. METHODS: Male Sprague-Dawley rats were subjected to neonatal colon irritation (CI) using CRD at 1 week after birth (CI group). At 6 weeks after birth, CRD was applied to these rats with a pressure of 20 to 90 mm Hg, and changes in the mean arterial pressure (MAP) were measured at baseline (i.e., without any drug administration) and after the administration of different doses of DA-9701. RESULTS: In the absence of DA-9701, the MAP changes after CRD were significantly higher in the CI group than in the control group at all applied pressures. In the control group, MAP changes after CRD were not significantly affected by the administration of DA-9701. In the CI group, however, the administration of DA-9701 resulted in a significant decrease in MAP changes after CRD. The administration of DA-9701 at a dose of 1.0 mg/kg produced a more significant decrease in MAP changes than the 0.3 mg/kg dose. CONCLUSIONS: The administration of DA-9701 resulted in a significant increase in pain threshold in rats with CRD-induced visceral hypersensitivity.

Osteogenesis imperfecta is a rare congenital disease. It is a heterogeneous group of inherited disorders characterized by multiple bone fracture, blue sclera, hearing loss, abnormalities of dentition and widespread connective tissue ahnormality. We experienced a case of osteogenesis imperfecta diagnosed in utero by ultrasonogram and confirmed hy postnatal radiograph after delivery. We present the case with a hrief review of the literature.
