Figure 2. CTA/P showing a significant interval increase in the size of the heterogeneous left liver lesion, which now measures 11.5 cm in maximal dimension as compared with 7.8 cm on the prior CT scan four days earlier.

The lesion now has a more multiloculated appearance, highly suggestive of an abscess given the rapid interval change. There are new areas of hyperdensity along the inferior aspect of the lesion suggestive of areas of hemorrhage within the abscess.
