Robot-assisted partial splenectomy for benign splenic tumors: Four case reports

Figure 1 Imaging examinations of four patients. A and B: Computed tomography (CT) revealed a round, non-enhancing low-density lesion measuring approximately 90 mm in the lower pole of the spleen (arrows), which was consistent with a splenic cyst; C and D: CT revealed multiple oval-shaped low-density lesions in the upper segment of the spleen (arrows), with the largest measuring approximately 52 mm; E and F: Magnetic resonance imaging revealed a 40 mm well-defined mass in the lower pole of the spleen (arrows), which appears as a low signal on T1 weight and a high signal on T2 weight; G and H: CT revealed a round, non-enhancing low-density lesion measuring approximately 73 mm in the lower pole of the spleen (arrows).
