Background and Objectives: Hyperthyroidism can occur with pregnancy. Thyroid storm is a life-threatening exacerbation of hyperthyroidism. The mortality rate for thyroid storm remains surprisingly high at approximately 20%.

Case Report: A 21-year-old primigravida woman presented at 25 weeks, with severe pre-eclampsia and uncontrolled hyperthyroidism was scheduled for emergency cesarean section. Treatment includes rapid alleviation of thyrotoxicosis and general supportive care.

Thyroid function tests may not help in differentiating thyroid storm from symptomatic hyperthyroidism. The major risk of anesthesia in the poorly controlled thyrotoxic patient is thyroid storm, which must be aggressively treated with beta-blockers, iodide, and antithyroid drugs
