PURPOSE: To determine the magnetic resonance (MR) imaging findings of tuberculous arthritis, and the frequency-in such cases-with which tuberculoma occurs. MATERIALS AND METHODS: MR images of 26 patients (M:F, 14:12; mean age, 46.2 years) with pathologically proven tuberculous arthritis were retrospectively reviewed. The presence of joint effusion, subchondral erosion, synovial proliferation and soft tissue abscess, and whether the inner wall of this abscess was smooth, were assessed. In particular, we determined whether a nodular lesion which showed low SI on T1WI, central low SI with peripheral high SI on T2WI, and rim enhancement on contrast study, was a tuberculoma. RESULTS: The joints involved were those of the knee (n=7), hip (n=7), shoulder (n=4), sacroiliac region (n=3), elbow (n=3), and ankle (n=2). Joint effusion was noted in 15 cases (58%), and subchondral erosion in 24(92%). synovial proliferation was found in 23 cases (88%), and soft tissue abscess in 24 (92%). The inner wall of this abscess was irregular in 17 cases (71%). A tuberculoma was present in intra- or extra-articular soft tissue in 18 cases (69%). CONCLUSION: The MR findings of tuberculous arthritis were subchondral erosion, synovial proliferation, and soft tissue abscess. The presence of a tuberculoma in intra- or extra-articular soft tissue, a specific finding in tuberculous arthritis, was noted in 69% of our cases.

Giant cell tumor arising in the osteocartilaginous tissue of the larynx is extremely rare. The few reported cases have all occurred in men older than 20 years and the site of origin has been exclusively localized to the thyroid and cricoid cartilages that are known to undergo enchondral ossification. The formation of giant cell tumor in larynx is thought to be related to this enchondral ossification process. We report a case of giant cell tumor arising in the thyroid cartilage of a 39 year old man. CT scan of the neck revealed a well defined mass of soft tissue density replacing the right thyroid cartilage. Grossly the tumor was well demarcated with a distinctive pushing margin except for the area bordering the submucosa of the larynx where it showed focally an infiltrative pattern of growth. Microscopically multinucleated giant cells were found dispersed regularly among the spindle cells. Although mitoses were frequently noted in the spindle cells there was no atypicality or pleomorphism. Total laryngectomy was performed without further treatment. Postoperative follow up for 6 months has proved the patient to be alive and well without recurrence.

Granulocytic sarcoma is an extramedullary tumor composed of immature granulocytic cells ; metastasis to thebreast is extremely rare. We describe a case of metastatic granulocytic sarcoma of the breast. The primary site ofthe lesion was the sixth thoracic vertebra ; there was no evidence of leukemia in peripheral blood or bone marrow. Mammography showed a 2cm-sized high-density mass lesion in the upper portion of the left breast, while breastultrasonography revealed an oval-shaped mixed heterogeneous hypoechoic mass with mild posterior enhancement.

BACKGROUND: The aim of this study was to investigate the relationships between left ventricular ejection fraction (LVEF) and mortality and neurologic outcomes with post-cardiac arrest syndrome (PCAS) after out-of-hospital cardiac arrest (OHCA). METHODS: Patients with PCAS after OHCA admitted to the intensive care unit between January 2014 and December 2015 were analyzed retrospectively. RESULTS: total of 104 patients were enrolled in this study. The mean age was 54.4 ± 15.3 years, and 75 of the patients were male (72.1%). Arrest with a cardiac origin was found in 55 (52.9%). LVEF < 45%, 45-55%, and > 55% was measured in 39 (37.5%), 18 (17.3%), and 47 (45.2%) of patients, respectively. In multivariate analysis, severe LV dysfunction (LVEF < 45%) was significantly related to 7-day mortality (odds ratio 3.02, 95% Confidence Interval 1.01-9.0, p-value 0.047). CONCLUSIONS: In this study, moderate to severe LVEF within 48 hours after return of spontaneous circulation was significantly related to 7-day short-term mortality in patients with PCAS after OHCA. Clinicians should actively treat myocardial dysfunction, and further studies are needed.

BACKGROUND: Generally, it is difficult to differentiate uterine malignant mixed Mullerian Tumor(MMMT) from endometrial carcinom in radiological and clinical aspects. Our purpose is to investigate MR findings that distinguishes MMMT from endometrial carcinoma. MATERIALS AND METHODS: We retrogradely evaluated the magnetic resonance imaging findings of pathologically proven 5 cases of malignant mixed Mullerian Tumor(MMMT) and 13 endometrial carcinomas to know the differential points of these two tumors originating in the endometrial cavity. The size of the mass, presence or absence of myometrial or uterine cervical invasion, growth pattern of the mass, signal intensity and degree and pattern of contrast enhancement were analyzed and compared. RESULTS: The length of the long axis of the MMMT was 1.5-9.0cm(average, 5.7cm) but that of the endometrial carcinoma was 0.5-6.0cm(average, 2.5cm). Invasion of uterine cervix which was found in 3 MMMT cases, dilated the endometrial cavity and the lumen of the uterin cervix and showed the pattern of growing into the external os. Invasion of uterine cervix was found in only one case of endometrial carcinoma. The presence or absence of myometrial invasion, the signal intensity and homogeneity on T1-and T2-weighted images, and the degree and patterns of contrase enhancement showed no significant difference. CONCLUSION: Any specific finding to differentiate MMMT from endometrial carcinoma was not ascertained. However, MMMT can be suspected if the size of the endometrial mass is greater than 5cm and if the mass dilates the enocervical canal and invades the uterine cervix.

Aneurysms of the pulmonary artery are rare, with mycotic aneurysms occurring most frequently. This latter type may also occur in association with a lung abscess or septicemia, particularly in drug addicts. As far as we are aware, the radiologic findings of mycotic aneurysm of the pulmonary artery have not been reported in Korea. We present the simple chest radiographs, as well as the CT and angiographic findings ,of a case of aneurysm of the pulmonary artery which was successfully embolized using a coil.

Undifferentiated sarcoma is one of the rare primary malignant tumor of the liver typically occur ring in later childhood. It has also been referred to embryonal sarcoma or malignant mesenchymoma. In Korea, three child and two adult cases have been reported to date in liter ature. We experienced a case of undifferentiated sarcoma in a 65- year- old female who presented with abdominal pain and right upper quadrant mass . Contrast-enhanced abdominal CT scan revealed a well demarcated mass with low at tenuation and sept ation at left lobe of the liver and the mass showed hypovas cular pattern on hepatic angiography. On cross section, the tumor was well demarcated from the adjacent liver by afibr ouspseudocapsule and showed cystic degener ation. Pathologically, the tumor was consistent with an undifferentiated sarcoma of the liver.

Congenital insensitivity to pain with anhidrosis (CIPA) is a rare, autosomal-recessive disorder characterized by the clinical triad of indifference of pain, anhidrosis and heat intolerance.Because of their lack of autonomic response to noxious stimuli, the determination of adequate depth of anesthesia in the CIPA patient undergoing surgery is a major challenge.We experienced a patient with CIPA who had minor procedures three times under the general anesthesia, in which bispectral index (BIS) was maintained at 40-50 by adjusting sevoflurane concentrations with 50% nitrous oxide.The low end-tidal sevoflurane concentrations (<1.2 vol%) were required to keep the target BIS while vital signs remained stable throughout the surgery in each operation.BIS monitor may be a valuable tool to guide the depth of anesthesia in patients with CIPA.
