Sudden Paralysis in an American Football Player! Monster Football?

Area of Science:

• Endocrinology
• Neurology
• Internal Medicine

Background:

• Ascending paralysis can mimic various neurological disorders, including Guillain-Barré syndrome.
• Periodic hypokalemic paralysis is a rare condition often associated with specific ethnicities and dietary factors.
• Factitious hyperthyroidism is a rare cause of electrolyte disturbances and neuromuscular symptoms.

Observation:

• A patient presented with ascending paralysis following diarrhea, initially suspected as Guillain-Barré syndrome.
• Prominent hypokalemia was noted, prompting consideration of periodic hypokalemic paralysis.
• The patient denied unusual dietary intake or exercise preceding the symptoms.

Findings:

• The paralysis and hypokalemia were ultimately attributed to factitious hyperthyroidism induced by surreptitious triiodothyronine (T3) intake.
• This represents an unusual presentation of hyperthyroidism mimicking primary neurological conditions.
• The diagnosis required careful investigation into the patient's history and biochemical markers.

Implications:

• Highlights the importance of considering endocrine disorders in the differential diagnosis of neuromuscular paralysis.
• Underscores the need for thorough patient history and biochemical evaluation to identify iatrogenic or factitious conditions.
• Emphasizes the potential for thyroid hormone abuse to cause severe metabolic and neuromuscular derangements.
