Diffuse large B-cell non-Hodgkin’s lymphoma associated with bilateral carotid-cavernous fistulas in an elderly woman

An 74-year-old woman presented with a 2-month history of left proptosis, left eye chemosis, left abducens nerve palsy and cervical lymphadenopathy. She was noted to have bilateral carotid cavernous fistulas and was treated with transvenous coil embolization. The diagnosis of diffuse large B-cell non-Hodgkin’s lymphoma was only confirmed 4 months later, despite a high index of suspicion, after clinical deterioration. This is, to our knowledge the first reported case of non-Hodgkin’s lymphoma associated with bilateral carotid cavernous fistulas.
