Introduction: focal liver lesions comprise a heterogeneous group of entities such as benign and malignant, solid or cysts, vascular, inflammatory masses and metastasis among others. Objective: To report focal liver lesions in children, clinical features, imaging and therapeutic behavior. Patients and Methods: A descriptive, retrospective study based on a review of 16 case histories of children with focal liver lesions in the period from January 2007 to January 2012. Liver abscesses were excluded. Results: 68.75%¹¹ were male and 31.25%⁵ females, mean age 9.5 years (range: 10 days - 14 years). Focal lesions were benign: Hemangioma 4/16 (25%), liver hematoma 4/16 (25%), hepatic cyst 3/16 (18.75%), nodular focal hyperplasia 1/16 (6.25%) and adenomas 1/16 (6.25%) and malignant: Hepatocellular carcinoma 2/16 (12.50%) and hepatoblastoma 1/16 (6.25%). Most patients (56.25%) were asymptomatic, 3/16 (18.75%) had abdominal pain, 3/16 (18.75%) and palpable mass 2/16 (12.5%) jaundice. The lesion was identified by abdominal ultrasound in all patients and only 56.25% (9/16) needed tomography with contrast. To 43.75% (7/16) underwent tumor markers and of these 42.85% (3/7) reported neoplasm. Normal hepatic function reported in 75% of cases. Conclusion: An abdominal ultrasound is the method of choice for the diagnosis and management of focal liver lesions, while the origin of them, guide therapeutic conduct.
