횡문근융해증은 다양한 원인에 의해서 발생하며, 생명이 위독할 수도 있는 질환이다. 저자들은 횡문근융해증이 있는 환자에서 진단과 치료에 있어 MRI와 골주사의 중요성을 경험하였기에, 이에 그 특징을 보고하는 바이다. Rhabdomyolysis is a potentially life-threatening disease which may result from a variety of causes. We describe the features of magnetic resonance imaging(MRI) and bone scintigraphy, and their importance for diagnosis and treatment of a patient with rhabdomyolysis.

Intestinal obstruction occurs rarely as a cause of acute abdominal pain during pregnancy. It is very difficult to make diagnosis, as nausea, vomiting and abdominal pain are commonly associated with pregnancy, and X-rays are avoided if possible. However, delayed diagnosis can cause intestinal strangulation, which results in a high incidence of maternal morbidity, mortality, premature labor, and fetal loss. The incidence of intestinal obstruction seems to increase at the time of rapid uterine size changes such as between 16~20 weeks, 32~36 weeks or even in the puerperium. The possibility of intestinal obstruction must always be kept in mind when a pregnant woman with an operation scar on her abdomen develops abdominal pain. We present a case of small bowel obstruction during early pregnancy with a brief review of the literature who had the history of right salpingo-oophorectomy and appendectomy operation.

Background: Rib fractures are the most common injuries resulting from blunt chest trauma. The sensitivity of conventional radiogrphy in showing the rib fracture is limited especially in whom involving the cartilage part of the rib. We investigated the rib fractures, those overlooked on conventional radiography, with the use of ultrasonography in minor blunt chest trauma. Materials and Methods: From september 2002 to March 2004, 40 patients (21 women and 29 men, mean age 43.3±15.1,range 16~85 years), with minor blunt chest trauma showing no evidence of rib fractures on conventional radiography, were admitted for examination with ultrasonography. Logistic regression analysis was done to outlined the clinical predictors of these incidious rib fractures. Results: A total of 15 (35%) patients showed rib lesions, whereas 25 (65%) patients had no evidence of rib lesions. Fractures of rib associated with a periosteal hematoma was the most common finding in ten (66.7%) patients followed by the rib fracture of the rib alone in four (26.7%) patients and subperiosteal hematoma alone in one (6.6%) patient. A total of eight (53.3%) patients had bony rib fractures, whereas seven (46.7%) patients had chondral rib fractures. Age (p=0.280), gender (p=0.431), type of etiology (p=0.823), duration of pain (p=0.470) and site of trauma (p=0.923) did not appear as significant predictors for these rib fractures. However, involved part of the rib showed a significant correlation with either age (p=0.043) or duration of pain (p=0.036). Bony rib fractures significantly occurred in elderly patients, and the duration of pain in patients with bony rib fractures was significantly longer than that of the patients with chondral rib fractures. Conclusions: Ultrasonography is a useful imaging method in showing the rib fractures those overlooked on conventional radiography in minor blunt chest trauma, and no significant clinical feature exists as a predictor for these insidious fractures. However, bony rib fractures significantly occur in elderly patients and result in a longer duration or pain.

Neurosonography is an excellent modality for imaging a wide array of intracranial pathology of the infant and the newborn. Periventricular high echos were prominent for the premature infant, but there are some difficulties in differentiate normal periventricular high echo from periventricular leukomalacia. White matter indices on neurosonography of 152 healthy newborn babies were measured and analized, with their gestational age, method of delivery, birth weight, APGAR score(1 min and 5 min), diagnosis and labaratory data. The gestational age of babies at birth (p=0.0001) and the delivery with Caesarian section (p=0.0263) were related statistcally to high white matter index. The babies with metabolic disease had higher white matter index than other disease group or normal control group. On the basis of these results, We speculate that in addition to gestational age of infants, delivery method and their disease status may play an additional role in presenting ldgh periventricular echo on neurosonography. It is possible to predict the size of non pathologic periventricular high echo and to give more information for further study plan.

Percutaneous needle biopsy is a commonly used diagnostic procedure with a high accuracy and a low complication rate. However, one of the undesirable complications is tumor seeding in the biopsy tracts. Authors expreienced a implantation metastasis through the bioipsy tract. So we report this case with clinical findings.

MRI is the most valuable imaging study in evaluation of spines. But conventional 2 dimension MR evaluation with axial and sagittal images of cervical neural foramen is limited by section thickeness, signal-to-noise problems, CSF flow artifacts and oblique direction of neural foramina. We added oblique sagittal images in the cervical MRI study of 32 patients and compared the MRI findings to clinical symptoms and the EMG results. The results were as follows. 1.The neck pain had correlations with the MRI findings as central disc protrusion and maximal cord compression (p<0.05). 2.The radiating pain had significant correlations with the MRI findings of foraminal narrowings on oblique sagittal images(p<0.01). 3.The radiculopathy on the EMG study had significant correlations with the MRI findings of foraminal narrowing on oblique sagittal images.

Changes in bone denity were recognized in the long bones (humerus) of premature babies on plain x-ray radiographs of chests in short term interval. This study was designed to estimate the osteopenia of premature babies and to find reliable causes of osteopenia. Plain x-ray radiographies of 20 premature babies (group A) were taken on the day of birth and about 10 day after birth. The humeral cortial indeces and the patterns of bone density were evaluated each time. Gesational age, birth weight. duration of total parenteral nutrition and duration of phototherapy of subjective babies were recorded. For comparison, 20 term babies (group B) were studied, too. Stastistical significances were noted between the changes of bone density and gestational age and birth weight (P=0.0064, 0.0007). Decreased bone density were seen in premature babies in short interval. There is a significant relation between changes of bone density and durations of phototherapy (P=0.0233)

The cloacal malformation is a congenital abnormaly in which urinary, genital, and intestinal tracts converge into a common flow structure, the cloaca. It is seen exclusively in phenotype female. The anomaly of the persistent cloaca results from partial failure of the urorectal septum to descend and devide the cloaca. Authors experienced a case of cloacal malformation of vaginal configuration with high recto-vaginal communication.

To detect the MRI findings related to The low back pain and sciatica according to age group, authors used tree model analysis of 80 patient's grading their low back pain and sciatica, with their lumbar MRI findings. And the results were as follows: 1. In teens and twenties(n=22), the low back pain was related to high maximum of spinal canal narrowing and large sum of disc degeneration, and the sciatica was related to the psoas spine ratio. 2. In thirties and forties(n=33), the sum of disc degeneration, the sum of foraminal narrowing, the maximum of disc degeneration affected the low back pain, and the sum of disc degeneration, disc herniation and maximum of canal narrowing were related to sciatica. 3. In fifties and sixties(n=23) the low back pain was related to large sum of foraminal narrowing and small psoas spine ratio, and thesciatica was largely affected by high maximum of foraminal narrowing and some by large sum of canal narrowing and large sum of disc degeneration.
