A Case of Multiple Splenic Lymphangiomas Diagnosed by Percutaneous Needle Biopsy

Lymphangioma of the spleen is an extremely rare disease in adults, and performing splenectomy has been considered necessary for its diagnosis and treatment, but the diagnosis of an isolated splenic mass lesion without performing splenectomy is a challenging problem. Herein, we report on a case of multiple splenic lymphangiomas that were found incidentally in a 56-year-old female; these lesions were diagnosed by percutaneous splenic biopsy without splenectomy. We suggest that this approach is a reasonable option for benign looking-appearing splenic tumors because splenectomy and its postsplenectomy complications can be avoided.

Unusual Infarction of the Accessory Spleen or Polysplenia in Two Children: Case Report

The usual imaging findings of common splenic infarction are well known, while the findings for splenic infarctions in the accessory spleen or polysplenia are rare; these unusual imaging findings may make the diagnosis difficult. We report here on two patients who have complained of abdominal pain, and they were diagnosed as splenic infarction that developed in either the accessory spleen or as has having polysplenia. We can diagnose splenic infarction that unusually develops in the accessory spleen or polysplenia when we identify a round, hyperechoic, avascular solid mass on US, or when we identify a round, rim-enhancing, hypodense solid mass with adjacent inflammatory changes and a small amount of ascites on CT that is adjacent to the normal spleen or in one of splenules of polysplenia in the clinical settings of acute abdominal pain.

Imaging of Nontraumatic Benign Splenic Lesions

The spleen is one of the largest organ in the reticuloendothelial system and plays an important role in theac-tivation of immune response. It is the organ most commonly injured after blunt abdominal trauma, and malig-nantlesions such as lymphoma, or these due to metastasis, occur not infrequently. Even so, it is ignored even inabdominal ultrasonography. Some benign splenic lesions, however can cause severe symptoms and result in high mortality, and their accurate diagnosis is therefore essential. This study describes the imaging findings andhistopathologic features of various nontraumatic benign splenic lesions.

The Sonographic Measurement of the Length of Spleen in Normal Children

PURPOSE: The purpose of this study was to establish the guidelines for normal splenic length by sonographic measurement. MATERIALS AND METHODS: In 481 children (age range : 2-16years, M:F=1.5:1), abdominal sonography for the purpose of health screening was carried out, and the greatest length of spleen between the dome and tip was measured. Correlation and regression analysis was used to determine whether the relationship between splenic length and a patient's age, height, weight and body surface was statistically significant. RESULTS: The length of the spleen gradually increased according to age. Correlation and regression analysis showed significant positive correlation (p<0.0001) between splenic length and age (r=0.610) height (r=0.630), weight (r=0.598), and body surface (r=0.628). CONCLUSION: From the mean values of spleen length in children, an index useful for clinical application might be derived.
