Anabolic steroid abuse causing recurrent hepatic adenomas and hemorrhage

Figure 1 T1-weighted magnetic resonance imaging (MRI) of multiple hepatic adenomas. A: MRI at initial presentation demonstrates a heterogeneous-appearing, well-circumscribed mass measuring 10.6 cm x 10.6 cm in segments 2 and 3 of the liver and several smaller masses in the right liver. The largest mass has an enhancing capsule and demonstrates areas of internal T1 hyperintensity and hypointensity, as well as T2 hyperintensity, characteristic of an adenoma with intralesional hemorrhage; B: Three months after left lateral segmentectomy and steroid cessation, the lesions in the right liver appear approximately 40% smaller and enhance more homogeneously on T1-weighted MRI, indicating regression. Images have been electronically adjusted to illustrate lesions.
