Leiomyosarcoma (LMS) of the small intestine is a rare tumor, accounting for about 1% of all malignant mesenchymal lesions in the gastrointestinal tract. Since small bowel tumors are initially asymptomatic and nonspecific, delayed diagnosis and treatment are common. We found that a 44-year-old male patient who came in for lower abdominal pain had partial obstruction in the small bowel. Multiple ascites and ileal tumors involving peritoneal seeding were observed from his abdominal computed tomography. He was diagnosed as epithelioid LMS involving peritoneal transition after surgical resection, and the outpatient department has planned for a conservative therapy with observation. To the best of our knowledge, ileal epithelioid LMS accompanying a huge omental mass, with a size of 18 cm in dimension, and peritoneal seeding has not yet been reported in Korea. We report this rare case with literature review.

Alimentary lymphoma accounts for approximately 5% of neoplasm and diffuse lesion is more common than solitary nodular form in dogs. An eleven year-old male Yorkshire terrier was examined because of nonspecific gastrointestinal symptoms such as anorexia and vomiting for 10 days. An abdominal mass was palpated, which was originated from small intestinal wall in abdominal ultrasonography. Small intestine was obstructed by hypoechoic mass and lost normal layering and measured 24.5m. After fine-needle aspiration, septic peritonitis due to intestinal rupture occurred and emergency surgery was performed. Solitary mass was found in small intestine and diagnosed as alimentary lymphoma through histopathologic examination. Conclusively, abdominal ultrasonouaphy could verify the thickened bowel, loss of wall layering and decrease of motility and percutaneous ultrasound-guided fine-needle aspiration is considered as useful diagnostic technique, especially in nodular form of alimentary lymphoma.

Intussusception is a serious disease where part of the intestine slides into an adjacent part of the intestine. Adult intussusception is mainly due to benign or malignant neoplasm. Therefore, in most cases of adult intussusception, treatment by surgery would be preferable to conservative therapy. However, we report on a 28-year-old female patient who underwent intussusception operation delayed 3 months. Abdominal computed tomography 3 months ago showed a small bowel intussusception measuring 20 cm long. Three months later, the previously identified small bowel intussusception appeared without change. The patient underwent surgery, and ectopic gastric mucosa was observed in the biopsy. Therefore, Meckel's diverticulum was diagnosed.

Gastrointestinal stromal tumor is a rare tumor which arises from the whole gastrointestinal tracts and most of it is detected in the stomach. It is uncommon with small intestine originated gastrointestinal stromal tumor and more uncommon with lymphatic metastasis. We experienced an unusual case of the small bowel gastrointestinal stromal tumor during experimental autopsy. Two primary tumors with central necrosis were detected in the ileum. The sizes of each tumor were $6.1{\times}3.4{\times}4.0$ cm and $3.7{\times}4.2{\times}3.2$ cm. There was extensive lymphatic metastasis on the greater omentum and mesenteric, iliac lymph nodes were also involved. With histologic findings, the eosinophilic spindle cells were densely distributed. Immunohistochemical findings were CD117 (-), CD34 (+), desmin (-), and S-100 protein (-). Therefore, we diagnosed the tumors as small bowel gastrointestinal stromal tumors with broad lymph node mestasis.

Objective: To evaluate the usefulness of MR imaging for diseases of the small intestine, emphasizing a comparison with CT. Materials and Methods: Thirty-four patients who underwent both CT and MR imaging using FLASH 2D and HASTE sequences were analyzed. All patients had various small bowel diseases with variable association of peritoneal lesions. We compared the detectabilities of CT and MR imaging using different MR pulse sequences. The capability for analyzing the characteristics of small intestinal disease was also compared. Results: MR imaging was nearly equal to CT for detecting intraluminal or peritoneal masses, lesions in the bowel and mesentery, and small bowel obstruction, but was definitely inferior for detecting omental lesions. The most successful MR imaging sequence was HASTE for demonstrating bowel wall thickening, coronal FLASH 2D for mesenteric lesions, and axial FLASH 2D for omental lesions. MR imaging yielded greater information than CT in six of 12 inflammatory bowel diseases, while it was equal to CT in six of seven neoplasms and inferior in five of seven mesenteric ischemia. In determining the primary causes of 15 intestinal obstructions, MR imaging was correct in 11 (73%) and CT in nine (60%) patients. Conclusion: MR imaging can serve as an alternative diagnostic tool for patients with suspected inflammatory bowel disease, small intestinal neoplasm or obstruction.

Small bowel metastasis of pleomorphic carcinoma of the lung is very rare. A 58-year-old man was admitted to our hospital with abdominal palpable mass in the right upper quadrant area. He underwent right middle and lower lobectomy for early stage pleomorphic carcinoma of the lung approximately 3 months ago. USG-guided biopsy was performed for abdominal mass. Pathologic examination revealed a metastatic pleomorphic carcinoma from the lung. He received chemotherapy followed by radiation therapy but died due to septic shock caused by intestinal stenosis and adhesion. We report the first case of small bowel metastasis by pleomorphic carcinoma of the lung after curative surgery.

Backgrounds/Aims: Although cancer survivors are at higher risk of developing second primary malignancies, cancer surveillance strategies for them have not yet been established. This study aimed to identify first primary cancers that had high risks of developing second primary exocrine pancreatic cancer (EPC). Methods: Data on individuals diagnosed with primary cancers between 1993 and 2017 were obtained from the Korea Central Cancer Registry. The standardized incidence ratios (SIRs) of second primary EPCs were analyzed according to the primary tumor sites and follow-up periods. Results: Among the 3,205,840 eligible individuals, 4,836 (0.15%) had second primary EPCs, which accounted for 5.8% of the total EPC patients in Korea. Between 1 and 5 years after the diagnosis of first primary cancers, SIRs of second primary EPCs were increased in patients whose first primary cancers were in the bile duct (males 2.99; females 5.03) in both sexes, and in the small intestine (3.43), gallbladder (3.21), and breast (1.26) in females. Among those who survived 5 or more years after the diagnosis of first primary cancers, SIRs of second primary EPCs were elevated in patients whose first primary cancers were in the bile duct (males 2.61; females 2.33), gallbladder (males 2.29; females 2.22), and kidney (males 1.39; females 1.73) in both sexes, and ovary (1.66) and breast (1.38) in females. Conclusions: Survivors of first primary bile duct, gallbladder, kidney, ovary, and female breast cancer should be closely monitored for the occurrence of second primary EPCs, even after 5 years of follow-up.

개에서 이물, 신생물, 유문동비후, 위수술, 전해질불균형, 위확장성 염전 등에 의한 비정상적인 위 배출시간은 임상에서 소화기 질환으로 중요하다. 그러므로 위장관 운동이상에 대한 정확한 진단을 위하여 정상적인 위장관 운동시간에 대한 자료가 필요하다. 이 연구의 목적은 개에서 기존의 BIPS를 이용하는 검사 방식이 아닌 국내에서 개발한 방사선 비투과성 Kolomark를 이용한 위배출시간 검사에 대한 임상적 유용성에 대한 기초자료를 제공하기 위한 것이다. Beagle 9마리가 이번 실험에 사용되었으며 평균 체중 평균 10.3kg이며 평균 2.5살이었다. 검사를 위해 12시간 금식을 시행하였으며 화학적 보정은 하지 않은 채 검사 직전 하루 사료급여량의 25%용량에 Kolomark 1개의 capsule과 함께 급여하였고 2, 4, 8, 12시간 때 Ventrodorsal, Right lateral자세로 촬영하였다. 관심판독부분은 분문에서 위유문부까지의 위장 전체를 관찰하였으며 분석방법으로는 각 시간대별로 위장 내에 남아있는 Kolomark를 카운트하여 비모수검정인 Friedman 검정방법을 이용하여 P값이 0.05 미만인 경우를 유의한 것으로 판정하였다. 구강으로 Kolomark를 섭식 후 위에서 소장으로 완전히 Kolomark가 빠져나가는데 걸리는 평균시간은 7.55시간이었다. 이번 연구에서 성숙한 개에서 음식물 투여 후에 나타나는 위장관 통과시간을 Kolomark를 이용하여 정상적인 위장관 운동시간에 대한 기초자료가 되리라 판단된다.

카포시 육종은 후천성 면역 결핍 증후군(acquired immunodeficiency syndrome; 이하 AIDS)와 연관되어, 피부, 점막과 여러 장기를 침범하는 다발성의 혈관성 결절로 나타나는 신생물을 일컫는다. AIDS와 연관되어 생기는 위장관 카포시 육종은 내장에 파종성 질환으로 가장 흔하게 발생한다. 우리는 다양한 장기를 침범하여 복통과 함께 장관 내 출혈을 유발한 드문 카포시 육종의 영상 소견에 대해 보고한다. 회장 대장내시경을 통해 말단 회장, S자 결장, 직장 내 다양한 병변이 발견되었으며 소장 투시검사로 공장과 회장의 병변을 확인할 수 있었다. 복부 골반 전산화단층촬영에서 회장 내 조영증강된 다양한 납작한 병변과 복강 내 크기가 커진 림프절을 발견하였다. 조직병리학 검사에서 카포시 육종으로 최종 진단이 된 환자는 항레트로바이러스제로 치료를 시행 받았다. 최근 AIDS 환자의 수가 늘고 있는 상황에서, AIDS와 연관된 Kaposi's sarcoma의 영상학적 소견을 숙지하는 것은 영상의학과 의사를 비롯한 임상의사들에게 빠른 진단과 치료뿐만이 아니라 예상치 못한 AIDS의 감염 위험에 노출될 수 있는 의료진의 안전을 위해서도 필수적이다.
