Arteriovenous malformation (AVM) is a lesion involving a high-flow vascular malformation, which is one of the causes of massive gastrointestinal bleeding. In the pediatric population, AVM is quite rare in the gastrointestinal tract, and the most common primary site is the colon. A small bowel is a rare primary site of AVM, and only 1 case has been reported in Korea. Here, we report on a case of AVM found in the distal ileum of a 14-year-old girl who complained about recurrent lower abdominal pain only without a gastrointestinal hemorrhage. In the previous research literature, a small bowel AVM can be diagnosed through detecting the existence of an enhancing nidus of the intestinal wall at the arterial phase, accompanied by an early draining vein as it appeared on a dynamic contrast-enhanced abdominal computed tomography. In our case, the pathologically confirmed AVM of the distal ileum showed a dot-like enhancement within the thick low-attenuating submucosal layer of the terminal ileum.

Zinner's syndrome is a rare congenital abnormality of the mesonephric duct. Unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction are the triad of maldevelopment of the mesonephric duct which comprises Zinner's syndrome. It is an extremely rare case, in that approximately 100 cases only have been reported worldwide. We discovered a rare developmental anomaly with other mesonephric duct-associated abnormalities, Zinner's syndrome with a presumed ectopic prostate and triorchidism and do report here.

Solid pseudopapillary tumor (SPT) is a low grade malignant tumor in the pancreas, and extrapancreatic SPT is extremely rare. We report a case of a 61-year-old woman who complained abdominal pain with diffuse tenderness. She was diagnosed with extrapancreatic SPT with extensive peritoneal dissemination and hepatic metastases. Although a few cases have reported imaging findings of extrapancreatic SPT, there have been no reports of extrapancreatic SPT with aggressive tumor behavior and dismal prognosis. Although imaging features closely resembled those of classical pancreatic SPTs, malignant transformation of extrapancreatic SPT should be considered when focal discontinuity of the tumor capsule with ill-defined margin and invasion of adjacent structures were identified.

BACKGROUND: There has been increasing interest in facial contouring procedures throughout Asian countries. As such, botulinum toxin A injections for masseteric hypertrophy have become a common procedure provided to patients who desire non-surgical correction of a square-angled mandible. We published a retrospective review of our initial results and our technique and treatment protocol in 2005. We also completed a long-term follow-up of the results (average follow-up period of 4.28 years) and the efficacy of repeated injections in 2010. The purpose of the current study is to systematically evaluate the changes to the masseter muscle at weekly intervals to determine the physiologic effects of botulinum toxin A injection. METHODS: Eight patients were prospectively followed on a weekly basis after botulinum toxin A injection for masseteric hypertrophy. Eight patients were followed for 15 weeks and four patients were followed for 25 weeks. Changes in the thickness of the muscle were recorded and analyzed. RESULTS: A reduction in the muscle thickness was found during the clenching phase of the muscle in the first week followed by a reduction in thickness during the resting phase in the second week. The reduction in muscle thickness continued until the eleventh week after which there was a gradual, but incomplete, return of muscle thickness over the study period. CONCLUSIONS: There is a predictable, phasic reduction in muscle thickness after botulinum toxin A injection for masseteric hypertrophy. This reduction first occurs during the clenching phase followed by a concomitant reduction during the resting phase. Maximal size reduction occurs at 11 weeks followed by gradual muscle size recovery.

BACKGROUND: As society changes, patients have high expectations of plastic surgery and rapid recovery after surgery. A thread-based facelift meets these requirements and is growing in popularity. METHODS: Former thread lifts were either floating or fixed types. The authors used both types. Using a vertical line from the lateral orbital rim as the center, the anterior face was lifted with floating-type threads and the lateral face was lifted with fixed-type threads. The Blue RoseTM thread was used for the combined-type facelift, as it is stronger than other threads. Improvements were measured using the Global Aesthetic Improvement Scale (GAIS). RESULTS: Eighteen patients out of 28 were followed over 3 months. Five patients (28%) reported a GAIS score of 2, 10 patients (55%) had a GAIS score of 3, 2 patients (11%) had a GAIS score of 4, and one patient was unsatisfied with the surgical results. Results showed improvements in 83% of the patients. CONCLUSIONS: The combined, minimally invasive, thread-based facelift has some benefits. First, the functional anatomy of the face is considered. Second, the pulling force of the threads is stronger than formerly used threads. Third, especially in Asian patients, the postoperative broadening of the malar area can be minimized. Thus, a combined thread lift using Blue Rose threads can provide a natural-looking and strong facelift.

BACKGROUND: Combining blepharoptosis correction with double eyelid blepharoplasty is common in East Asian countries where larger eyes are viewed as attractive. This trend has made understanding the relationship between brow position and height of the palpebral fissure all the more important in understanding post-operative results. In this study, authors attempt to quantify this relationship in order to assess whether the expected postoperative brow descent should be taken into consideration when determining the amount of ptosis to correct. METHODS: Photographs of ten healthy female study participants were taken with brow at rest, with light elevation and with forceful elevation. These photographs were then viewed at 2 x magnification on a computer monitor and caliper was used to measure the amount of pull on the eyebrow in relation to the actual increase in vertical fissure of the eye. RESULTS: There was a positive, linear correlation between amount of eyebrow elevation and height of the palpebral fissure, which was statistically significant. Brow elevation increased vertical fissure, and thereby aperture of the eye, by 18%. CONCLUSIONS: Although the eye-opening strength as well as height of the palpebral fissure is improved with ptosis repair, the true effectiveness of ptosis surgery is diminished by the associated descent of the brow from relief of the involuntary frontalis muscle action and this should be taken into account prior to surgical intervention. Regardless, the combination of frontalis muscle relaxation and the increased eye-opening strength from ptosis repair gives the eye and the periorbital region a more natural look.

Anteromedial force to the knee in an extended position can cause an avulsion fracture of the proximal fibula with combined injuries to the posterolateral ligaments. Avulsion fractures of the proximal fibula are rare and current management of these fractures is based on few descriptions in literature. Various surgical methods of fixation for these fractures have been reported, but there is still no standard treatment modality. Anatomic reduction of these fractures is technically difficult, and failure of reduction may cause posterolateral instability, secondary arthritis and other complications. We present our experience with two such cases of comminuted avulsion fractures of the proximal fibular with posterolateral ligament ruptures surgically fixated with a locking compression hook plate and non absorbable sutures.

Wernicke's encephalopathy is a common complication of thiamine deficiency among chronic alcoholics. However, there have been few reports about MR imaging findings, including the diffusion-weighted changes of this neurologic disorder, in nonalcoholic patients. We present here a rare case of acute Wernicke's encephalopathy that developed in a patient who received prolonged total parenteral nutrition for his pseudomembranous colitis. The MR imaging, including the diffusion-weighted imaging, was performed at the onset of disease and during follow-up. The diagnosis was made by the characteristic MR imaging findings and it was supported by the clinical features. The initial and follow-up MR imaging findings with diffusion-weighted imaging changes are described and correlated with the clinical status.

Multiple myeloma usually shows homogeneous enhancement on contrast-enhanced Magnetic Resonance imaging (MRI), and is accompanied by a monoclonal gammopathy in serum or urine. We report a case of nonsecretory myeloma, the diagnosis was difficult due to the absence of a monoclonal gammopathy and the presence of atypical imaging features.

OBJECTIVE: To investigate whether fetal microchimeric cells were detected in ovarian tissues with pelvic endometriosis. METHODS: Ovarian tissues with endometriosis were obtained from five women who had at least one live-born son and who underwent enucleation of endometriotic cyst or oophorectomy after a diagnosis of endometriotic cyst. Control tissues were obtained from five women with endometriosis who had no pregnant history. Tissue sections were analyzed with fluorescence in situ hybridization for the presence of fetal cells, defined by X and Y chromosome. RESULTS: Fluorescence in situ hybridization using paraffin-embedded ovarian specimens was performed successfully. Male cells were found in ovarian tissues from all five patients. No male cells were found in ovarian tissues from all five controls. CONCLUSION: Fetal microchimeric cells, possibly from feto-maternal cell trafficking were detected in ovarian tissues with endometriosis were obtained from women who had prior male pregnancies. Further study is necessary to understand the role of persistent fetal microchimeric cells in the progression of endometriosis.
