title: Diffuse large B-cell lymphoma in the sphenoid sinus mimicking fibrous dysplasia in CT and MRI.
abstract: We present a 70-year-old man with lymphoma who presented with a right eye movement disorder. CT examinations showed 'ground-glass' appearance extending around the right sphenoid sinus which suggested fibrous dysplasia. However, biopsy from the mass histologically proved it to be diffusing large B-cell lymphoma and positron emission tomography examinations revealed increased fluorodeoxyglucose (FDG) uptake around the right sphenoid bone and multiple spinal bones. After chemotherapy for lymphoma, abnormal FDG uptake disappeared from the body.
