Computed tomography with intravenous contrast showed a 3.2cm x 4cm x 1.8cm multiseptated cystic lesion in the left hepatic lobe and an ill-defined heterogeneous hyperdensity within the peripheral right hepatic lobe measuring 3cm x 1.3cm (Figure 1).

Imaging also revealed a new pericardial effusion that was not present on previous imaging (Figure 2).
Low-power view of the interface between an endometriotic nodule and liver parenchyma. Notice the large endometrial type glands surrounded by endometrial type stroma in the superior portion of the image. These are separated from the liver parenchyma (lower right portion) by a band of fibrosis. The liver parenchyma displays macrovesicular steatosis. Hematoxylin & Eosin, 40x.

Final pathology was consistent with hepatic endometriosis (Figures 3 and 4).
High-power view of an endometriotic nodule. Endometrioid type glands of varying shape and size show characteristic columnar lining, within a cellular endometrial type stroma. The inset shows a portal tract for comparison (from top to bottom: vein, artery, bile ducts); notice the small round shape of the bile ducts and lack of cellular stroma. Hematoxylin & Eosin, 200x.
