Background: Rhabdomyolysis with influenza infection is rarely reported in adults. We report here influenza A induced rhabdomyolysis and anterior compartment syndrome (ACS)., Case Report: This case report describes a 43-year-old woman exhibiting influenza A induced rhabdomyolysis. High levels of creatine kinase (97,000 IU/L) and high titer of anti-influenza A virus antibody (H3N2) (320 ×) with negative anti-influenza B virus antibody were observed. T2 fat suppression muscle MRI imaging showed high-intensity signals in rectus femoris, vastus lateralis, adductor magnus, and semimembranosus (SM) muscles. The existence of ACS was suspected out. Muscle biopsy showed that fiber size variations exist without infiltration of inflammatory cells. The symptoms and muscle MRI findings of T2 fat suppression imaging was markedly improved., Conclusions: Muscle MRI T2 fat suppression imaging is a useful method to monitor influenza A induced rhabdomyolysis. We should keep in mind the possibilities of rhabdomyolysis and ACS in patients with influenza A infection presenting serious muscle pain.
