a In the CT soft tissue window, a sagittal plane of a porcine tongue with two pseudotumors (yellow *) with a low HU. b In the CT soft tissue window, a coronal plane of a porcine tongue with one pseudotumor is shown with a much higher HU and better delimitability, but a worm-like shape (framed in yellow). c In the CT lung window, a sagittal plane of a porcine tongue with a pseudotumor showing lack of expansion due to the appearance of air pockets (red arrows) around the pseudotumor due to insufficient rest (< 3 days). d Frozen tongue with two pseudotumors. The tissue appears much more homogeneous due to the frozen state
