title: Diffuse hepatic amebiasis detected by FDG PET/CT.
abstract: A 39-year-old man presented with sudden decreased visual acuity in his left eye. Orbital CT and MRI revealed a soft tissue lesion in his left orbital apex. FDG PET/CT showed increased FDG uptake by the left orbital lesion, abnormal focal FDG uptake in the soft tissues of the external ears, and abnormal heterogeneous FDG activity throughout the liver. Percutaneous liver biopsy, external auditory canal discharge, and stool specimens revealed amebiasis. The patient responded to antiamebic therapy, and his lesions improved. The case demonstrates that during its early stage, hepatic amebiasis may be associated with a relatively heterogeneous pattern of FDG uptake.
