case_images: The computed tomography (CT) imaging of the patient. (a) The CT scan shows a sharply demarcated mass with branching calcification shadows inside. (b) Slight enhancement at the arterial phase. (c) Persistent enhancement at the vein phase. (d) CT re-examination after 2 years showed no enlarged mass or lymph nodes.

case_images: The mass had branching calcification shadows inside (Figure 1(a)), a slightly enhanced appearance during the arterial phase (Figure 1(b)), and persistent enhancement during the vein phase (Figure 1(c)). At the most recent follow-up, CT scans indicated the absence of an abdominal mass (Figure 1(d)).
case_images: The surgical specimens and pathological of the patient. (a) Complete excised mesenteric mass. (b) Concentrically arranged broadened mantle zones form an onion-skin appearance (pointed by the arrow).

case_images: Macroscopically, the specimen was measured to be 6.9 cm * 5.5 cm * 5.3 cm with a soft texture and a grey-white section peppered with calcifications (Figure 2(a)). Under the microscope, the lymphoid tissue showed hyperplasia, the usual germinal structure was replaced by the mantle zone with an onion skin appearance (Figure 2(b)).
