Abstract

Benign lesions of the liver represent diagnostic dilemmas, clinically and radiographically; however, certain clues can help the extensive differential diagnosis of both benign and malignant processes. Hemangiomas and simple cysts have very distinct and very specific radiographic characteristics, and if diagnosed, no further work-up is necessary. The remaining benign lesions have significant overlap, even though there are some more common characteristics to each of the entities. Still, differentiation of any particular lesion outside simple cysts or hemangioma may be difficult. It is reasonable and relatively simple, with minimal invasiveness, to perform US- or CT-guided, percutaneous core-needle biopsies. It is recommended that core biopsies be performed, because many of the benign entities have some overlapping histologic features, and if fine-needle aspirations are performed, a definitive diagnosis may be difficult to obtain. A definitive pathological diagnosis still cannot be made in some cases, even after needle biopsy. Therefore, a surgical resection or wedge resection may be necessary if a benign process cannot be definitively ruled out.
