Singhi et al describe the clinical and pathologic features of a group of 18 patients presenting with a pseudotumor secondary to segmental atrophy of the liver. The authors conclude that these pseudotumors occur in the setting of of an intralesional abnormal and/or thrombosed vessel and, histologically, may progress through several "stages": from areas of parenchymal collapse with brisk ductular proliferation (early lesions), nodular elastosis (more advanced lesions), and finally nodular fibrosis (end-stage lesion).
