Fig. 1. (A) Ultrasound image of the accessory spleen shows a hypoechoic mass with a well-defined margin. (B) Contrast-enhanced axial computed tomography image shows a well-defined, hypo-enhancing mass, measuring approx. 4.5 cm, in the left upper quadrant of the abdomen. (C) On axial T2-weighted image, the mass appears as a solid lesion with moderate-to-high signal intensity. On contrast-enhanced MR image obtained in the (D) pre-contrast phase, (E) portal phase, and (F) subtraction image of portal phase, the tumor shows relatively high signal intensity in the pre-contrast image and no enhancement except for a subtle and thin peripheral enhancement, which is indicative of coagulative necrosis due to ischemia. (G) Technetium-99m phytate scintigraphy and single-photon emission computed tomography (SPECT) images do not show radiotracer uptake within the abdominal mass.
