case_images: Abdominal MRI. (A) Coronal and (B) Axial T2 HASTE (Half-Fourier single-shot turbo spin-echo) demonstrating uniformly hyperintense T2 signal from the enlarged cisterna chyli. (C) Coronal reformat imaging illustrates the branching feeding lymphatic channels. The lesion measured 12.8 cm craniocaudally, 3.4 cm transversely, and 2.7 cm anteroposteriorly.

case_images: This lesion measured 12.8 cm craniocaudally, 3.4 cm transversely, and 2.7 cm anteroposteriorly (Figure 1).
case_images: CT Chest with IV Contrast. (A) Axial section demonstrating a round, well-marginated, right retrocrural lesion with homogenous attenuation (mean 13.3 HU) without enhancement and no apparent invasion of adjacent structures. (B) Coronal and (C) sagittal reformats of the same lesion demonstrate its tubular structure extending from the level of the T12 vertebral level inferiorly to the T8 vertebral level superiorly.
