An enlarged spleen can be caused by infections, cirrhosis and other liver diseases, blood diseases characterized by abnormal blood cells, problems with the lymph system, immune diseases, or other conditions. Therefore, knowing the normal size of the spleen is helpful for the diagnosis of spleen and may be useful for follow-up. Ultrasonographic examination may be considered normal size if the maximum length is less than 12 cm and less than 5 cm in thickness, but may vary depending on sex and race. We aimed to present the normal range of spleen size by measuring the spleen size by ultrasonography in 20's normal adult Korean. The length of the male spleen was 10.95±1.07 cm and the width was 4.48±0.61 cm. The female length was 9.20±1.30 cm and the width was 3.55±0.44 cm. There was a significant difference (p<0.001). The spleen length increased with increasing height (r=.57) and there was a significant positive linear relationship with increasing spleen length as body weight increased(r=.63). In normal adults, 5 men and 2 women had a spleen length of more than 12 cm and 2 men with a size exceeding 13 cm.

Splenic irradiation in chronic myelogenous leukemia is reserved for patients who have painful splenemegaly despite chemotherapy and/or inoperable splenomegaly because of huge size. The role of splenic irradiation is diminution of painful splenomegaly and indirect effect of splenic irradiation on unirradiated hematopoietic and lymphoreticular tissue such as reduction of leukocyte count and increase of hemoglobin level. We report on a useful clinical method for splenic irradiation in chronic myelogenous leukemia. We have used sonography as the tool of simulation. The portal size using modified method is smaller than the field size of conventional simulation, and so this method suggests that useful to irradiation of huge splenomegaly, effective shielding of critical organ and the downfall of complication during irradiation of spleen.

A 5-year-old male German shepherd dog was presented with a 4 day-history of anorexia and depression. Abdominal radiographs showed a large soft tissue mass and loss of serosal detail. Ultrasonographs revealed splenomegaly with the lacy pattern parenchyma, perivenous hyperechoic region at the splenic hilum, and loss of splenic venous flow. Computed tomographic findings included the enlarged non-enhanced spleen except perivenous region at the splenic hilum and a whirled soft tissue mass at the splenic hilum. Exploratory laparotomy confirmed the diagnosis of splenic torsion. Ultrasonographic findings including lacy appearance, hyperechoic perivenous echogenicity and absence of splenic blood flow and CT findings including no or minimal enhancement of the spleen and a whirled appearance of splenic pedicle could be useful for diagnosing isolated splenic torsion in the dog.

Choledochal cyst is considered to be congenital anomalies of the biliary tract, characterized by varying degrees of cystic dilatation at various segments of the biliary tract. A 20-month-old girl was admitted to Eul-Ji general hospital because of abdominal distension. Physical examination revealed marked splenomegaly and hepatomegaly with nodular surface and hard consistency. Laboratory examination showed elevated transaminase level, alkaline phosphatase level and gamma glutamyltranspeptidase level without evidence of cholestasis. Diagnostic imaging study revealed choledochal cyst with Todani classification type 1. Cholecystectomy and Roux-en-Y choledochojejunostomy was performed, and wedge liver biopsy showed diffuse periportal fibrosis with cirrhotic change and ductular proliferation in the portal area. After operation, hepatosplenomegaly and abnormal laboratory examinations improved rapidly, and in 9 months, the liver and spleen became not palpable. We experienced a case of choledochal cyst complicated by liver cirrhosis on pathology in a 20 month-old girl, and removal of choledochal cyst improved clinical manifestations rapidly.

Kikuchi disease is a type of benign, self-limiting necrotizing lymphadenitis that occurs most commonly in young women and usually manifests as palpable cervical lymph nodes and fever. Patients with an unusual location of lymph node involvement can be misdiagnosed with malignant disease. Here, we report a case of Kikuchi disease in a 15-year-old girl presenting with persistent fever for 2 weeks. Imaging studies, including ultrasonography, CT, and ¹⁸F-fluorodeoxyglucose PET/CT, revealed splenomegaly and enlarged lymph nodes in the neck, axilla, abdomen, retroperitoneum, and inguinal region. Laparoscopic excision of the celiac lymph nodes confirmed histiocytic necrotizing lymphadenitis, also known as Kikuchi disease. Conservative treatment with corticosteroids improved the patient's condition.

Purpose: Acute febrile illness in children frequently accompanies with abdominal symptoms such as vomiting, diarrhea, and abdominal pain, even if its etiology is not occured from the gastrointestinal tract. If the etiology of fever was unknown and the fever was accompanied with abdominal symptoms, we should be concerned about whether the etiology of fever was originated from the gastrointestinal tract or interpretated from the abnormality in the gastrointestinal tract. This study was performed to evaluate the diagnostic value of abdominal ultrasonography in patients with fever and abdominal symptoms. Methods: We reviewed retrospectively the medical records of abdominal ultrasonographic (US) findings of 60 cases of acute febrile illness with abdominal symptoms at department of Pediatrics, Ulsan Dongang General Hospital during the period from January 1994 to June 1995. Results: The abnormal abdominal US findings obtained were as follows. 1) The abnormal US findings were seen in 56 cases (93.3%). 2) The most common abnormal US finding was the enlarged mesenteric lymph nodes in 52 cases (86.7%) 3) The enlarged mesenteric lymph nodes with or without intra-abdominal fluid were seen in 30 cases (50.0%) of a wide variety of illnesses, so their diagnostic values were absent. 4) The enlarged mesenteric lymph nodes and splenomegaly with or without ileocecitis were seen in 7 cases. Among them, 4 cases (6.7%) were confirmed as typhoid fever. 5) The US findings in 6 cases of typhoid fever were the enlarged mesenteric lymph nodes in all cases (100%), splenomegaly in 4 cases (66.7%), ileocecitis in 1 case (16.7%), enlarged mesenteric lymph nodes and splenomegaly in 4 cases (66.7%), enlarged mesenteric lymph nodes, splenomegaly and ileocecitis in 1 cases (16.7%). 6) The enlarged mesenteric lymph nodes and the abnormalities around the appendix were seen in 7 cases (11.7%), which were confirmed as appendicitis all. 7) The thickening of wall in urinary bladder was seen in 2 cases (3.3%) of acute cystitis and acute hemorrhagic cystitis. 8) The subtle thickening of wall in colon was seen in 1 cases (1.7%) of shigellosis. Conclusions: The enlarged mesenteric lymph nodes, splenomegaly and ileocolitis on the abdominal ultrasonography in patients with fever and abdominal symptoms aree suggestive findings of typhoid fever. The enlarged mesenteric lymph nodes and the abnormalities around the appendix on abdominal ultrasonography make the rapid diagnosis of acute appendicitis and its complications, when physical examination is difficult in small children and diagnosis of their illnesses is obscure in patients with fever and abdominal pain.

Mass mortality occurred in mud loaches, Misgurnus mizolepis, cultured in ponds located in Kunsan. External signs of affected fish showed hemorrhage of skin and fins, Internally, pale liver with congestion, enlarged kidney, and spleen and enteritis exhibited. Causative bacteria isolated from liver, spleen, and kidney of the disease fish. In biochemical tests, the isolates were similar with those of the reference strains, A. sobria. The aerolysine gene from the present isolate was amplified PCR with the primer SOBF and SOBB for A. sobria. The isolate was identified as A. sobria on the basis of those tests. In virulence test, the present isolate resulted in the development of clinical signs identical to those in naturally infected fish. The present results conclude that the present isolate is A. sobria and can be a pathogen which causes motile aeromonad septicemia to mud loach.

Radiation therapy was the treatment of choice for CML in the past, in the form of SI or radioactive phosphorus. Its use has been replaced to a large extent by various chemotherapeutic agents. Recently SI in CML has been used, both to relieve painful splenomegaly and to take advantage of an indirect effect of SI on unirradiated bone marrow. We have treated 15 CML cases who had a huge spleen during chemotherapy or even after chemotherapy by 6 MV linear accelerator during the past two years at the Division of Radiation Therapy, Kang Nam St. Mary's Hospital, Catholic College. Response to SI has been rated according to the scoring system of Roger W. Byhardt, et al. which evaluated the splenic and hematologic response as well as the response of disease-related systems. According to this scoring system, most patients demonstrated a significant relief of splenomegaly along with improvement of hemogram. And we observed the change of Karnofsky Performance Status after SI, and survival after a confirmative diagnosis and SI.
