Pregnancy complicated by juxtaglomerular cell tumor of the kidney: A case report

Figure 1 Imaging examinations. A: Contrast-enhanced ultrasonographic examination of the kidney shows a medium echogenic mass presenting with low enhancement characterized by a “slow in and fast out” pattern; B: Computed tomography (CT) image selected from the enhanced CT urography scan sequence shows an endogenic round-like mass in the upper pole of the right kidney, which is approximately 3 cm in diameter; C: Coronal magnetic resonance imaging shows a right upper pole renal mass (endogenic type) with no significant abnormalities in the bilateral adrenal glands.
