From "suspected appendicitis" to definitive diagnosis: the role of contrast-enhanced ultrasound-guided biopsy in a rare case of colonic inflammatory myofibroblastic tumor in an adolescent.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Inflammatory myofibroblastic tumor (IMT) of the colon is a rare mesenchymal neoplasm of intermediate biological potential that can mimic acute appendicitis in adolescents. We report a 13-year-old male presenting with right lower quadrant pain and fever. Initial ultrasound revealed a large heterogeneous hypoechoic mass. Contrast-enhanced ultrasound (CEUS) clearly differentiated a peripherally enhancing viable rim from a central necrotic area, enabling precise ultrasound-guided core needle biopsy that yielded a definitive preoperative diagnosis of IMT. The patient underwent laparoscopic right hemicolectomy with negative margins and had an uneventful recovery. This case illustrates that a systematic CEUS-guided biopsy approach is safe and accurate, allowing targeted sampling of viable tissue and guiding appropriate surgical resection. Recognizing the diagnostic value of CEUS in complex pediatric abdominal masses may help avoid misdiagnosis and unnecessary extensive surgery.
