Abstract

Rhabdomyolysis is a rare but serious complication of hypothyroidism, typically associated with precipitating factors such as medication interactions, strenuous exercise, and illicit drug use. We present a unique case of rhabdomyolysis in an 89-year-old female due to severe hypothyroidism without identifiable precipitating factors. Laboratory results revealed markedly elevated creatine kinase (CK) levels and acute kidney injury (AKI). The diagnosis was confirmed by critically elevated thyroid-stimulating hormone (TSH) and low free thyroxine (FT4) levels. Prompt initiation of levothyroxine supplementation and fluid resuscitation led to clinical improvement and downward trend in creatinine and CK levels. This case highlights the importance of considering hypothyroidism in the differential diagnosis of rhabdomyolysis and the need for timely T4 supplementation and supportive care to prevent severe complications.
