N2 - BACKGROUND: Hepatocellular adenomas are rare tumors that can occur in patients with glycogen storage disease type I.CASE SUMMARY: We herein report two cases of histologically proven hepatocellular adenomas in patients with glycogen storage disease type I. Magnetic resonance imaging (MRI) was performed after bolus injection of gadoxetate disodium, a liver-specific gadolinium-based MRI contrast agent. In the present cases, some of the hepatocellular adenomas showed unexpectedly a "bull's eye" appearance on T2-weighted and post-contrast images, which was not previously described as imaging findings of hepatocellular adenomas in glycogen storage disease. A bull's eye appearance on T2-weighted images can be encountered in both benign (i.e., abscess) or malignant (i.e., epithelioid hemangioendothelioma, cholangio-carcinoma, and metastases) hepatic lesions.CONCLUSION: We present two cases of hepatocellular adenomas in patients with glycogen storage disease type 1, in which gadoxetate disodium-MRI showed atypical imaging findings for hepatocellular adenomas. At present there is no systematic study evaluating MRI findings of hepatocellular adenomas in patients with glycogen storage disease, further studies are needed to specifically investigate this issue.
