Abstract

Septic cavernous sinus thrombosis (SCST) is a rare but fatal central nervous system infectious disease affecting the cavernous sinuses. Here, we report a case of 51-year-old woman presenting with new-onset unilateral retro-orbital headache lasting for 3 weeks and subsequent ipsilateral abducens nerve palsy. Brain magnetic resonance imaging revealed enlargement of the cavernous sinus with dural enhancement and ring-enhancing abscess in the adjacent temporal lobe. Although blood and cerebrospinal fluid cultures were negative, the patient was successfully treated with empirical antibiotic therapy. Although SCST is a possible cause of painful ophthalmoplegia, it should be kept in mind that in the early stage it may present only with headache without ocular symptoms.
