Horner’s syndrome (HS) has previously been reported in the literature as a complication of parathyroid surgery. It presents clinically with eyelid ptosis, miosis, enophthalmos, anhidrosis, and vascular dilatation, all of which result from a damaged sympathetic chain. Here, we report the case of a 45-year-old female patient who presented with miosis and eyelid ptosis following microwave ablation (MWA) of secondary hyperparathyroidism (SHPT). After 6 months of follow up, the patient’s miosis and ptosis was incompletely relieved. We aimed to try to avoid such devastating symptoms in future cases by exploring reasons for the destruction of the cervical sympathetic trunk.

Key words: cervical sympathetic trunk; Horner syndrome; microwave ablation; secondary hyperparathyroidism
