Popis: Background: Visual complications of endoscopic sinus surgery usually occur during or immediately after the surgery. We report a case of cavernous carotid aneurysm which developed and gradually worsened after endoscopic sinus surgery was performed. Case presentation: A 63-year-old woman with chronic rhinosinusitis resistant to conservative treatment underwent endoscopic sinus surgery. Despite the surgery being successful and without complications, diplopia developed 2 weeks later. Intracranial imaging revealed a giant cavernous carotid aneurysm as a likely cause of the diplopia. The patient underwent endovascular stenting treatment, and the diplopia was consequently reduced. Conclusions: We experienced a rare case of cavernous carotid aneurysm which started to develop 2 weeks after endoscopic sinus surgery. Possible causes of the aneurysm in this patient are an indirect effect of surgery, such as perioperative hypertension, and bacterial sinusitis.
