Concomitant cavernous sinus thrombosis and central serous chorioretinopathy in a patient with total ophthalmoplegia and monocular blindness: a case report

Cavernous sinus thrombosis (CST) is an unusual condition that can result in high mortality and morbidity rate if not treated immediately. CASE PRESENTATION: An Indonesian male, 47 years old, presented with total right ocular ophthalmoplegia followed by blindness, headache, ptosis, periorbital swelling, and hypoesthesia over the left V1 region. MRI of the brain showed suitable cavernous thickening until the right orbital apex, which in contrast showed enhancement suggestive of right Tolosa–Hunt syndrome. The patient was treated with a high dose of steroids, but the patient’s complaints did not improve. The patient underwent digital subtraction angiography and found CST. The optical coherence tomography was found to be central serous chorioretinopathy. He was treated with an antibiotic, anticoagulant, and extraction of the right maxillary molar was performed to remove the source of the infection. After 3 weeks, visual acuity and optical coherence tomography examination were improved. DISCUSSION: A comprehensive examination, such as digital subtraction angiography, is essential to confirm CST diagnosis for the patient to obtain the right therapy. This report highlighted the value of the prompt diagnosis of CST through neuroimaging and the importance of proper therapy in patient management. CONCLUSIONS: Early diagnosis, comprehensive examination, and proper treatment of CST will increase good prognosis.
