Key result
Administration of 10 mCi radioactive iodine triggered a recurrent attack of thyrotoxic hypokalemic periodic paralysis ten days later in a 37-year-old Turkish male with Graves' disease.
Why the study?
Does radioactive iodine treatment trigger recurrence of paralysis attacks in patients with thyrotoxic hypokalemic periodic paralysis?
Case Report (n=1)
Does radioactive iodine treatment trigger recurrence of paralysis attacks in patients with thyrotoxic hypokalemic periodic paralysis?
Radioactive iodine treatment may trigger a recurrence of paralysis attacks in patients with thyrotoxic hypokalemic periodic paralysis.
Supports closer follow-up during thyroid treatment in THPP; leaves open optimal prevention strategies.
Thyrotoxic hypokalemic periodic paralysis (THPP) is a rare complication of hyperthyroidism and an uncommon form of hypokalemic periodic paralysis. Its differentiation of more common forms of periodic paralysis is important because aggressive treatment can place the patient at risk for rebound hyperkalemia. Treatment of the underlying thyroid dysfunction cures the muscle symptoms. Here we describe a 37-year-old Turkish male with THPP whose paralysis attack recurred soon after administration of radioactive iodine.

Akar et al. (2005) conducted a case report in Thyrotoxic hypokalemic periodic paralysis (THPP) (n=1). Radioactive iodine (131I) was evaluated on Recurrence of paralysis attack. Administration of 10 mCi radioactive iodine triggered a recurrent attack of thyrotoxic hypokalemic periodic paralysis ten days later in a 37-year-old Turkish male with Graves' disease.
