Abstract
Neoplastic and nonneoplastic diseases may involve the liver with a regional distribution, which is defined as a non-focal process without any specific anatomic predilection. In this pictorial essay we review hepatic diseases commonly presenting with a regional distribution in the liver and describe the CT and MR imaging findings helpful for differential diagnosis. Knowledge of the characteristic imaging manifestations of neoplastic and non-neoplastic diseases affecting the liver regionally will facilitate an accurate diagnosis and result in the appropriate clinical management of these liver diseases.
