Thyrotoxic Periodic Paralysis (TPP) is a rare manifestation of thyrotoxicosis, resulting in periodic episodes of acute onset muscle weakness in the setting of hypokalemia. The thyrotoxic form of Hypokalemic Periodic Paralysis (HPP) is less studied than the more well-known familial form due to fewer reported cases and smaller prevalence. This case study presents a 30-year-old African American male with multiple episodes of acute lower extremity muscle weakness, tachycardia, and a history of heat intolerance. Abnormal findings on thyroid ultrasound coupled with increased thyroid related immunoglobulins led to a diagnosis of TPP related to exacerbation of newly-found Graves’ disease. The case study will further discuss the importance of imaging in assessing the etiology of TPP with review of relevant literature.
