Exercise-Induced Abdominal Wall Muscle Injury Resulting in Rhabdomyolysis and Mimicking an Acute Abdomen.

Abstract

Rhabdomyolysis is characterized by muscle necrosis and release of intracellular constituents, causing muscle pain, weakness, and myoglobinuria. This can be attributed to muscle injury after strenuous exercise. If the abdominal wall is involved, clinical presentation may resemble an acute abdomen. A 27-year-old woman, gravida 4 para 2, presented with swelling and pain of the mons pubis and abdominal pain after intense powerlifting 2 days prior. A computed tomography scan was performed, revealing abdominal wall inflammation. Although myoglobinuria was absent, there was high suspicion for rhabdomyolysis, which was confirmed by an elevated creatine kinase level. The patient improved after receiving intravenous fluids and abstaining from physical activity. Abdominal wall muscle injury resulting in rhabdomyolysis can imitate an acute abdomen in a healthy woman presenting with abdominal pain and swelling.
