Mesenteric Castleman disease on histopathology. Axial (a), coronal (b) and sagittal (c) contrast enhanced CT images of the abdomen in a 26-year-old male reveal a well-defined round homogenously enhancing mass in the mesentery in the left lumbar region anterior to the lower pole of left kidney with a mean attenuation of ~101 HU and central arborising calcification. Photomicrograph of the histopathological specimen (d) shows acellular areas comprising vessels with dense sclerotic walls and cellular areas comprising spindle cells with bland nuclear morphology and inflammatory cell infiltrate comprising plasma cells.
