Clinical examination, biochemistry and magnetic resonance imaging of the thighs were suggestive of muscle haematomas. These progressed significantly during the admission, requiring blood transfusion. Normal vascular anatomy on computed tomography, renal and liver function, and absence of infection made a bleeding diathesis more likely. This may be caused by coagulation defects, platelet disorders and vascular fragility. An undetectable serum ascorbic acid level confirmed the clinical suspicion of scurvy, and administration of vitamin C resulted in rapid improvement. Our case provides a structured approach to the diagnosis of bleeding disorders and scurvy, a treatable and potentially fatal disease which is often forgotten.
