Abstract
Out of various pathologies that affect the liver, focal liver lesion form an important group. Triphasic computed tomography is the imaging modality most often used to evaluate focal liver lesions. The purpose of this study was to evaluate the role of computed tomography in the diagnosis of liver lesions and to determine frequency of these lesions.

Highlights
Any lesions in the liver other than normal parenchyma which may or may not cause structural and functional abnormality of hepatobiliary system are defined as focal liver lesions
Triphasic liver computed tomography scan has gained acceptance as the preferred computed tomography technique for routine liver evaluation and it has helped in the decline of mortality and morbidity rates among patients with liver disease
Triphasic liver CT scan is a standardized procedure for the detection and characterization of a large variety of focal liver lesions.[14, 15]
Summary
Any lesions in the liver other than normal parenchyma which may or may not cause structural and functional abnormality of hepatobiliary system are defined as focal liver lesions. The prevalence of these lesions is different across geographic regions and ethnic groups. These lesions can be divided into benign and malignant.[1] There is wide spectrum of benign focal lesions. Most common amongst them are cysts, hemangiomas, hepatocellular adenomas (HCA) and focal nodular hyperplasia (FNH). In Pakistan hepatocellular carcinoma is the fourth most common hepatic disorder.[2]
