BACKGROUND: Fluid aspiration, percutaneous biopsy, and catheter drainage are standard minimally invasive methods of diagnosing @entity706 or @entity1778 in adults. OBJECTIVE: To determine the effectiveness of interventional radiologic techniques in diagnosing specific @entity1583 in @entity1 . METHODS: During a 4-year period, 22 @entity1 (16 male, 6 female; median age, 13 years) underwent 25 percutaneous biopsies, 6 fluid aspirations, 3 catheter drainages, and 1 needle localization for diagnosing suspected @entity1583 . RESULTS: For @entity978 , the procedures yielded 6 true-positive (TP) results, 2 @entity8125 ( @entity8125 ) results, and 2 false-negative (FN) results; for @entity1893 ( @entity1893 ), 14 TP results, 1 @entity8125 result, and 3 FN results; and for @entity1778 , 4 TP results and 3 FN results. Percutaneous biopsies yielded 16 TP results, 3 @entity8125 results, and 6 FN results. Aspirations and drainages yielded 8 TP results and 1 FN result. The one needle localization yielded a FN result. Overall sensitivity was 75%+/-7.3%; specificity, 100%; and accuracy, 77%+/-7.1%. CONCLUSION: Percutaneous biopsy of @entity706 is usually diagnostic. Drainage or aspiration of a fluid collection associated with @entity1893 or @entity1778 is often diagnostic and is less invasive than biopsy. These procedures are minimally invasive and effective for diagnosing pediatric @entity1583 .
