Intraoperative abdominal ultrasound in oncologic imaging

Figure 5 A 62-year-old female with renal cell carcinoma. A, B: Coronal (A) and axial (B) contrast-enhanced computed tomography images show a solid, hypervascular, 2.8 cm mass in the midportion - lower pole of the right kidney, consistent with a renal cell carcinoma; C, D: Intraoperative grayscale (C) and color Doppler ultrasound (D) identify a solid echogenic mass in the midportion - lower pole of the right kidney, with evidence of internal vascularity, consistent with a renal cell carcinoma; E: Intraoperative ultrasound image in a oblique transverse plane shows that the lesion abuts the hyperechoic renal sinus fat. This important information to guide the surgeon, in order that tumor-free margins are properly obtained at the time of resection.
