We report a case of a large asymptomatic Rathke cleft cyst in a 14-year-old boy. This cyst was of considerable size, measuring 2x1.8x1.8 cm, but did not produce any symptoms and was confined to the suprasellar area. The cyst wall was lined by pseudostratified ciliated columnar epithelium with goblet cells. The lining epithelium of the Rathke cleft cyst was immnoreactive for cytokeratin, EMA and CEA.

PURPOSE: To document the relative usefulness of true Fast-imaging steady-state precession(FISP) comparing to breath-hold turbo spin-echo(TSE), and half-Fourier single-shot turbo spin-echo(HASTE) as a fast T2-weighted sequence during hepatic MR imaging. MATERIALS AND METHODS: For 46 patients with 87 focal hepatic lesions(hepatocellular carcinoma, n=26; metastasis. n=5; cavernous hemangioma, n=37; cyst, n=19), we obtained MR imaging of the liver at 1.5T. True FISP, TSE with and without fat-suppresion(FS), and HASTE with and without FS images were obtained during one breath-hold. Images were compared on the basis of tumor detectability and lesion-to-liver contrast-to-noise ratio(CNR). Qualitative analysis of each imaging sequence was also performed in terms of hepatic contour, visibility of vascular landmarks and imaging artifacts. RESULTS: TSE-FS depicted more focal lesions(78/87, 90%) than other sequences(TSE, 75/87=86%;HASTE, 74/87=85%; HASTE-FS, 75/87=86%;true FISP,73/87=84%). However, there was no statistical significance between each sequence(p> .05). Using true FISP or HASTE, there was a statistically significant difference(p< .01) between the CNRs of solid tumors, crystal and hemangiomas. Additionally, true FISP sequence showed better hepatic contour, vascular landmarks and less artifacts comparing with TSE or HASTE regardless of FS(p< .001). CONCLUSION: True FISP sequence allows differentiation between solid tumors, hemangiomas and cystic lesions in terms of CNR, and provides better imaging quality than other fast T2-weighted MR sequences.

PURPOSE: This study was aimed to compare the results of a transanal repair with those of a transvaginal levatorplasty and to determine the long-term clinical outcomes according to the change in the depth of the rectocele after the procedure. METHODS: Of 50 women who underwent a rectocele repair from March 2005 to February 2007, 26 women (group A) received a transanal repair, and 24 (group B) received a transvaginal repair with or without levatorplasty. At 12 months after the procedures, 45 (group A/B, 22/23 women) among the 50 women completed physiologic studies, including anal manometry and defecography, and clinical-outcome measurements. The variations of the clinical outcomes with changes in the depth of the rectocele were also evaluated in 42 women (group A/B, 20/22) at the median follow-up of 50 months. RESULTS: On the defecographic findings, the postoperative depth of the rectocele decreased significantly in both groups (group A vs. B, 1.91 +/- 0.20 vs. 2.25 +/- 0.46, P = 0.040). At 12 months after surgery, 17 women in each group (group A/B, 77/75%) reported improvement of their symptoms. However, only 11 and 13 women (group A/B, 55/59%) of groups A and B, respectively, maintained their improvement at the median follow-up of 50 months. Better results were reported in patients with a greater change in the depth of their rectocele (> or =4 cm) after the procedure (P = 0.001) CONCLUSION: In both procedures, clinical outcomes might become progressively worse as the length of the follow-up is increased.

PURPOSE: Unlike males, inguinal hernia surgery in females is an uncommon surgical procedure. The efficacy of laparoscopic surgery for female hernia must be proven. This study compared the clinical characteristics of male and female hernia as well as the efficacy of laparoscopic surgery with that of open surgery in female hernia. METHODS: From March 2007 to February 2011, one surgeon (C.S.) at the authors' institution operated on 965 patients (male/female=884/81) who were each more than 19 years old. The female patients were divided into the laparoscopic (n=67, TEP/TAPP=66/1) and open surgery groups (n=14). RESULTS: The mean age of the female patients was lower than that of the male patients. The incidence of bilateral and direct hernia was higher in the male patients but the incidence of femoral hernia was higher in the female patients (0.6 vs. 8.6%, p<0.001). Among the 81 female patients, the mean age of the patients with femoral hernia was higher than that of the patients with other types of hernia (56.4+/-12.5/43.0+/-15.1, p<0.026). The operation times and pain scores of the two groups 7 days after surgery were comparable. CONCLUSION: The findings revealed a higher incidence of femoral hernia in the female patients than male patients. Patients with a femoral hernia were older than those with other types of hernia. Therefore, laparoscopic surgery must be considered for elderly female patients who have a high incidence of femoral hernia.

The aim of this study was to determine the usefulness of quantitative analysis of multiphasic dynamic contrast-enhanced magnetic resonance (MR) imaging in differentiating early homogeneously enhancing hemangiomas from hepatocellular carcinomas (HCCs). Four-phased dynamic MR imaging at 10 sec (first phase of dynamic contrast-enhanced imaging, P1), 35 sec (second phase, P2), 60 sec (third phase, P3) and 300 sec (delay phase, P4) immediately after intravenous administration of 0.1 mmol/kg Gadolinium-DTPA was obtained with 1.5-T unit with breath-hold multisection FLASH (fast low angle-shot) sequence (TR/TE, 113-130 msec/4.1 msec; flip angle, 80 degrees). Thirty-three HCCs and 18 hemangiomas, homogeneously enhanced on P1, were included in the study. The images were evaluated quantitatively (SNR, signal-to-noise ratio; and CNR, contrast- to- noise ratio of lesions). Quantitatively, mean CNR was higher for hemangiomas than for HCCs on all phases, and the difference in CNRs between hemangioma and HCCs was statistically significant on P3 and P4 (p < 0.0001). When the cutoff for CNR was set at a value of 7.00 on P3 and 1.00 on P4, sensitivity, specificity and accuracy were 94.4%, 93.9%, and 94.1% on P3, and 94.4%, 81.8%, and 86.3% on P4, respectively. There was no statistically significant difference in SNRs between HCC and hemangioma. The differential diagnosis between early, homogeneously enhancing hemangiomas and HCCs was more confidently made with CNRs of lesions on P3 and P4 in dynamic contrast-enhanced MR imaging.

Arrhythmogenic right ventricular cardiomyopathy (ARVC)/dysplasia is characterized by fibro-fatty replacement of the right ventricular myocardium. A 19-year-old soldier was admitted with sudden cardiac arrest that presented as ventricular fibrillation requiring cardiopulmonary resuscitation. His electrocardiogram (ECG) showed normal sinus rhythm with inverted T waves from leads V1 to V4 and isolated premature ventricular beats with a left bundle branch block (LBBB) pattern. Echocardiography showed that the right ventricle was enlarged with apical trabecular formation. The coronary angiogram was normal. Cardiovascular magnetic resonance imaging (MRI) showed thinning and fatty substitution of both the right and left ventricular free walls. Ventricular tachycardia (LBBB pattern) occurred frequently despite anti-arrhythmic drug treatment. His drug-resistant ventricular tachycardia was treated with an implanted cardiac defibrillator. Left ventricle involvement in ARVC is less common and more severe. Cardiac MRI is considered the best imaging technique for evaluating the right ventricle and diagnosing ARVC.

Hypolipidemic effect of biopolymers extracted from culture broth (CP), mycelia (MP), and fruiting bodies (FP) of Auricularia auricula-judae was investigated in dietary-induced hyperlipidemic rats. The experimental animals were administrated (100 mg/kg body weight) with different biopolymers, daily for 4 weeks. Hypolipidemic effects were achieved in all the experimental groups, however, FP was proved to be the most potent one. The administration of the FP reduced the plasma triglyceride, total cholesterol, low-density lipoprotein cholesterol, and atherogenic index by 24.3, 28.5, 36.4, and 40.9%, respectively, while increased the high-density lipoprotein cholesterol level (9.0%), when compared to the saline (control) administered group.

Many advances, including the development of antibiotics, the advent of diagnostic techniques and the use of nonsurgical drainage have decreased the mortality rate of pyogenic liver abscess. But, early prompt diagnosis and proper treatment is mandatory in gas-forming pyogenic liver abscess because it may run a fulminating course to death. Gas-forming pyogenic liver abscess mostly occurred to old diabetics. Symptoms of duration are shorter and the prognosis is poorer in the gas-forming than in the non-gas-forming liver abscess. We report three cases of gas-forming pyogenic liver abscess which occurred in old diabetic patients. They were successfully managed by parenteral antibiotics and early percutaneous drainage under sonographic guidance. Early and adequate drainage of pus by pigtail catheter may play a crucial role on the treatment of gas-forming liver abscess.
