Abstract
Angiomyolipomas (AMLs) are a benign mesenchymal tumor that typically occurs in the kidney and very rare in the liver. Even though these tumors can be diagnosed with imaging tecniques, diagnosis mainly relies on pathological findings. Because AMLs can mimic other hepatic tumors such as hepatocellular carcinoma (HCC) on radiologic images due to some of the features. We presented a giant hepatic AML case which mimicing hepatocellular carcinoma in imaging techniques. We suspected from hepatocellular carcinoma according to radiologic images, but biopsy result was hepatic angiomyolipoma. There are potential risks such as spontaneous rupture and malignant transformation of these tumors. The effective therapy of hepatic AML is surgical resection.
Highlights
Angiomyolipomas occurs most commonly in the kidneys and include smooth muscle, adipose tissue and vascular structures
The tumor showing the predominance of lipomatous tissue is probably to be correctly diagnosed; myomatous and angiomatous variant poses diagnostic problems since it is difficult to be distinguished from other tumors such as hepatocellular carcinoma (HCC), hemangioma, focal nodular hyperplasia, hepatic

Summary
Angiomyolipomas occurs most commonly in the kidneys and include smooth muscle, adipose tissue and vascular structures. Hepatic angiomyolipomas (AMLs) are very rare, benign, hepatic mesenchymal tumors, its diagnosis is difficult, its treatment remains controversial. This neoplasm found in both males and females, and most commonly in adult females (1). We presented a hepatic AML case which mimicing hepatocellular carcinoma due to hypervascularity on imaging techniques. A 57-year-old female admitted to a hospital with history of two months of back pain. She had type two diabetes for four years, taking oral antidiabetics and had a history of thyroidectomy ten years before. On physical examination vital signs were stable. No other pathologic sign on physical examination.
