calcified solitary fibrous tumor in the retroperitoneum: a case report and review of the literature. Preoperative images. a, b Images of plain computed tomography on the patient’s first visit. A mass with extremely high densities was located next to the undersurface of the right hepatic lobe and the right kidney (yellow arrows). It was 6.5 cm in the longest diameter. c An image of plain computed tomography 2 years after the patient’s first visit (yellow arrow). There were no remarkable changes of the mass in its appearance or size. d, e Magnetic resonance imaging on the patient’s first visit.
