Splenic pseudocyst is a rare complication of abdominal trauma. Although it is rare, splenic pseudocyst is well-documented in the literature. According to the current classification, approximately 30% of all splenic cysts or pseudocysts result from direct abdominal trauma. In addition, chronic pancreatitis leads to change of nearby organs with possible acute and chronic complications including splenic lesions. This unusual complication can occur in both emergent and nonemergent conditions. The useful diagnostic procedures to assess intrasplenic pseudocyst are sonogram, CT scan, splenic scan, and occasionally angiography. However, definite diagnosis of pseudocyst is possible only after splenectomy when the absence of epithelial lining is confirmed histologically. Splenic pseudocyst requires surgical resection. We experienced a 31-year-old man who confirmed of warmness in the left side of back with left upper quadrant abdominal pain for several months. First impression was splenic lymphangioma based on CT scan and sonogram finding. Splenectomy was performed. Microscopic examination revealed splenic pseudocyst with fibrous capsule without epithelial lining.

A mesothelial cyst of the round ligament is a rare cause of an inguinal mass. Clinically, it is frequently misdiagnosed as one of commoner diseases such as an inguinal hernia, femoral hernia, lipoma, and lymphadenopathy upon physical examination. Some previous reports elaborated the sonographic features of a mesothelial cyst of the round ligament. However, to our knowledge, few reports have described the CT features of a mesothelial cyst. We illustrated here the sonographic and multidetector CT features of a case of a mesothelial cyst of the round ligament that presented as an inguinal palpable mass and mimicked a metastasis in a patient with a Sertoli-Leydig cell tumor of the ovary.

PURPOSE: To carry out long-term follow-up of patients diagnosed with asymptomatic simple renal cysts (SRCs). MATERIALS AND METHODS: One hundred fifty-eight adult patients in whom SRCs were incidentally diagnosed by abdominal ultrasonography or abdominopelvic computed tomography between August 1994 and June 2004 were followed up for over 10 years. The retrospective analysis investigated sequential changes in the size, shape, and Bosniak classification of the renal cyst and analyzed risk factors for increased size and growth rate of the cysts. RESULTS: The median follow-up period was 13.9 years (range, 10.0-19.8 years). Median patient age was 54.1 years (range, 22-86 years). Mean maximal cyst size was 33 mm (range, 2-90 mm). Among all patients, 120 (76%) showed a mean increase in maximum renal cyst diameter of 1.4 mm (6.4%) per year. Age at initial diagnosis was a risk factor for increased renal cyst maximum diameter. The probability of an increase in maximum diameter of an SRC was 7.1 times greater in patients aged 50 years or older at diagnosis than in those aged less than 50 years. However, among patients with an increased maximum diameter, the mean growth rate was lower in patients aged > or =50 years than in those aged <50 years. CONCLUSIONS: About three-quarters of adult patients with accidentally diagnosed SRCs presented with an increased maximum diameter. The only risk factor for an increase in maximum diameter was age. In patients with an increase in the maximum diameter, the growth rate of the maximum diameter was 6.4% per year during 10 years and decreased with age.

OBJECTIVE: Ultrasonography (USG) of joints has a unique position for the diagnosis of joint diseases. Bone surface, cartilage, periarticular soft tissue and their pathologic changes can be assessed by USG. This study was aimed to compare the radiographic and ultrasonographic findings in osteoarthritis (OA) of the knee joint and to evaluate the usefulness of each modality to evaluate the disease early and determine the severity of the arthritis. METHODS: Fifty osteoarthritis patients classified by the American College of Rheumatology (ACR) clinical criteria from December 2002 to April 2003 were included in the study. Routine radiography (standing anteroposterior, lateral, skyline view) and systemic USG examination of both knee were performed. We compared the incidence of the radiographic and ultrasonographic abnormality related to the pathologic change of the knee OA and suggesting the severity of the OA which would help to decide the therapeutic modality. RESULTS: In patient with knee OA, plain radiography showed abnormal findings in 37/50 (74%) patients, but USG showed at least five abnormal findings in all 50 patients. The abnormal findings detected only by plain radiography were subchondral sclerosis and subchondral cyst (14% and 4% each). But, the thinning of cartilage (94%), Baker's cyst (94%), cartilage degeneration (54%), meniscal protrusion (44%), meniscal tear (34%), meniscal cyst (32%), and the pannus (22%) were detected only by USG. Among the findings shared by both method, joint space narrowing was detected better by plain radiography than USG, but fluid accumulation, spur, meniscal calcification and osteochondroma were detected more frequently by USG. CONCLUSION: USG is more sensitive to find the pathologic changes related to the knee OA and to diagnose OA than the plain radiography. But each of the plain radiography and USG have their own unique value for the evaluation of OA in the knee. So the USG supplements the plain radiography in the examination of the knee OA.
