A 4 year old female with acute lower abdominal pain was admitted with the diagnosis of periappendiceal abscess made by ultrasonography. At laparotomy, the appendix was normal, but the left ovary was twisted and necrotic. Appendectomy and left salpingo-oophorectomy were performed. The pathology of the appendix was normal, and the left tube and ovary were ischemic and had hemorrhagic necrosis. Pediatric adnexal torsion may be difficult to diagnosis clinically. Sonography is the preferred imaging study. It usually confirms a pelvic mass but may not establish the diagnosis. The correct diagnosis of adnexal torsion is often made at exploration. The most common erroneous diagnosis is acute appendicitis or periappendiceal abscess. Therapy for adnexal torsion remains controversial. While extirpation has been the standard of treatment in the past, there are current proponents of conservative therapy with adnexal sparing. Early diagnosis may lead to more frequent salvage of affected adnexa.

The objective of this paper is to present a digital method for improving the lateral resolution of the B-scan images in the medical applications of ultrasound. The method is based upon a mathematical model of the lateral blurring caused by the finite beam width of the transducers. This model provides a simple method of applying a recursive scheme for image restoration with fast computation time. The point spread function (P.S.F.) can be measured by the reflective signals after scanning the small pins located along the depth of interest. From the measured P.S.F., one can compute the coefficient matrices of the inverse discrete-time dynamic state variable equation of the blurring process. Then, a recursive scheme for deblurring is applied to the recorded B-scan to improve the lateral resolution. One major advantage of the present recursive scheme over the transform method is in its applicability for the space-variant imaging, such as in the case of the rotational movement of transducer.

A female, 14-year-old mixed dog weighing 4 kg and a female,8-year-old schnauzer dog weighing 6 kg showing vaginal discharges and vomiting for a few weeks were examined for the preoperative check of anterior cruciate ligament rupture and the recheck after the surgery of nephrectomy. There were no distinct abnormal signs except for the increased CBC at schnauzer dog on blood chemistry analysis. Radiographic and ultrasonographic findings were a large abdominal mass and a cyst-like hypoechogenic or anechogenic cavitary lesion on the ovary region. These findings were consistent with an ovarian cyst. Thereafter highly suspected ovarian cysts by diagnostic imaging were supported by high estrogen concentration on hormonal assay and the results of Pathologic examination as the unilateral ovarian cysts with secondary pyometra.

One woman, Sixty three years old, suffered from chest pain, abdominal pain, nausea and vomiting for about three months. Although many examinations, brain magnetic resonance imaging(MRI), chest computed tomography(CT), abdominal CT, gastric endoscope, abdominal ultrasonography, and so forth, was performed from every point of view, those were non-significant. At first, I wrongly diagnosed her case as disease of Soumin and gave Soumin Gwakhyangjeongkisan. But she complained of diarrhea and chest discomfort. I re-diagnosed her case as Soyangin Gyeolhyung and treated with Hyeongbangdojeoksan, herbal medicine, consisted of Rhizoma Rehmanniae(生地黃), Lignum Akebiae(木通), Radix Scrophulariae(玄蔘), Semen Trichosanthis(瓜蔞仁), etc. Three weeks have passed from first visit and she did not suffered from pain. I experienced the excellent effect of Hyeongbangdojeoksan to Soyangin Gyeonlhyung.

A 17-year-old neutered male Miniature Pinscher dog presented with a mass on the left side of the submandibular region. Fine needle aspiration revealed malignant epithelial cells from the salivary gland but no evidence of metastasis was found on radiography, ultrasonography, or computed tomography. The cervical mass was surgically resected, and the histopathological examination confirmed adenocarcinoma of the mandibular salivary gland. Seven months after the initial diagnosis, the dog is alive without any clinical signs. This report describes the clinical findings, cytology, diagnostic imaging, and histopathological characteristics of a mandibular salivary gland adenocarcinoma in a Miniature Pinscher dog.

급성 음낭 통증은 흔히 접하는 비뇨기계 임상증상이며 다양한 원인들이 있다. 그중에 고환정맥 혈전증은 드물지만 급성 음낭 통증을 유발하는 원인 중 하나이다. 혈전증은 우리 몸 어느 곳에서나 발생할 수 있는 흔한 질환이지만 고환정맥에 발생한 혈전증은 아직까지 국내에 보고된 바가 없다. 저자들은 급성 음낭 통증으로 내원한 남자 26세 환자에서 고환정맥의 혈전증을 경험하였기에 이를 보고하는 바이다.

Gallbladder (GB) polyp is a mucosal projection into the GB lumen. With increasing health awareness, GB polyps are frequently found using ultrasonography during health screening. The prevalence of GB polyps ranges between 1.3% and 9.5%. Most patients are asymptomatic and have benign characteristics. Of the nonneoplastic polyps, cholesterol polyps are most common, accounting for 60%-70% of lesions. However, a few polyps have malignant potential. Currently, the guidelines recommend laparoscopic cholecystectomy for polyps larger than 1 cm in diameter due to their malignant potential. The treatment algorithm can be influenced by the size, shape, and numbers of polyps, old age (>50 years), the presence of primary sclerosing cholangitis, and gallstones. This review summarizes the commonly recognized concepts on GB polyps from diagnosis to an algorithm of treatment.

Ingestion of foreign bodies (FBs) is a common phenomenon among young children. Plain radiography is the first step diagnostic modality to detect the radio-opaque FBs. And computed tomography has been recommended by several guidelines as useful modalities for diagnosing ingested FBs. However, there is a risk of radiation exposure, making it burdensome to use in asymptomatic patients. Ultrasound (US) is not a commonly used technique for diagnosing ingested foreign bodies. However, US can provide real-time imaging with good resolutions without radiation exposure in pediatric patients. Herein, we report two pediatric cases of metallic foreign body ingestion that were successfully diagnosed using US for localizing foreign bodies. This study indicates that US may be used as an alternative method for detecting the localization of metallic foreign bodies in the gastrointestinal tract without exposure of radiation, particularly in pediatric patients.

Extra-gastrointestinal anisakidosis is rare. We herein report an Anisakis pegreffii infection in a patient with hepatic anisakidosis diagnosed based on its molecular identification. A 71-year-old male patient had a hepatic tumor presenting as a low-density area of 20 mm in diameter in segment 6 of the liver on abdominal ultrasonography, computed tomography, and magnetic resonance imaging. The surgically resected pathological specimen revealed a necrotizing eosinophilic granuloma containing nematode larvae, possibly an Anisakis larva. Molecular and phylogenetic analysis demonstrated Anisakis larvae belonging to A. pegreffii. The present results will help identify and characterize unknown Anisakis species in histological sections.

This case report describes a case of isolated (not associated with other anomalies) lower vaginal hypoplasia complicated by megalourethra (urethral dilatation) due to frequent urethral sexual intercourse in a regularly menstruating (hypomenorrheic) woman. The patient was a 24-year-old woman who underwent transperineal ultrasonography as well as magnetic resonance imaging followed by sequential cystoscopic and vaginoscopic examinations. Finally, a pull-through procedure was used to create a new vagina. The main outcome measure was patent vagina formation. The procedure successfully corrected isolated lower vaginal hypoplasia. The postoperative course was smooth, with the restoration of regular intercourse in the correct location. It was concluded that all gynecologists should have increased awareness of rare female genital anomalies to avoid serious sequelae, particularly in newly married patients.
