Role of BrIDA scan in evaluating of a liver mass

Diagnosis of a liver mass is so important in approaching to the patient. Hemangioma and Focal Nodular Hyperplasia can be managed conservatively. All other tumoral masses must be treated surgically. In addition to RBC scan for Heangioma, BrIDA scan for FNH can be diagnostic. We report a young woman with large liver mass that BrIDA scan showed FNH and we review the lituratures. Case presentation: A 23 year- old girl was referred to our department with epigastric and right upper quadrants pain from months ago. She had many imaging. In ultrasound and CT scan there was 100 x 70 mm mass in the caudate lobe. RBC liver scan was negative for liver hemangioma. Then we decide to use hepatobiliary scintigraphy. The TC-99m-Br-IDA scan showed radiotracer accumulation in the caudate lobe of liver in early and 4 hours image suggests FNH. This agent is taken up by kupffer cells in focal nodular hyperplasia. The patient managed conservatively after 5 month follow-up her mass had not increase in size. In conclusion, BrIDA scan can help in diagnosis of focal nodular hyperplasia from other her masses especially adenoma, so we can manage patient conservatively
