Contrast-Enhanced Ultrasound Guided Biopsy of Undetermined Abdominal Lesions: A Multidisciplinary Decision-Making Approach

Figure 1

Grayscale ultrasound detected a heterogeneous hypoechoic abdominal lesion in a 48-year-old male. No necrotic area was shown with conventional ultrasound (a). CDFI detected blood flow in the peripheral area of the lesion (b). In CEUS, large and irregular nonenhanced necrotic area was displayed inner lesion (c). With CEUS guidance, 16-gauge coarse needle percutaneous biopsy (arrow) was performed successfully in the viable areas of the lesion (d). Histopathological results proved it was a gastrointestinal stromal tumor (e).
