抄録

A 71-year-old man with drooping right superior palpebra reported orbital pain with deficits in the optic, oculomoter, trochlear, and abducens nerves but no nasal symptoms. Magnetic resonance imaging (MRI) showed a cavernous sinus abnormality and a soft tissue mass in the anterior ethmoid sinus. The first diagnosis was Tolosa-Hunt syndrome, and corticosteroid treatment was instituted. His response to corticosteroid treatment was poor and the anterior ethmoid mass was examined, resulting in a pathological diagnosis of non-Hodgkin malignant lymphoma, clinical stage IV A due to involvement of bone marrow. We assume that the cavernous sinus abnormality was due to malignant lymphoma.
