Abstract

We report the case of a healthy 36 year old man who suffered from foot pain lasting for weeks, without having a specific medical history relating to it. The clinical evaluation was interpreted as a transfer metatarsalgia caused by a splayfoot. The radiographs revealed no pathology except the splayfoot deformity. Due to persistent pain and swelling of the entire forefoot, after two weeks of conventional treatment, magnet resonance images (MRI) and a blood sample were taken. The laboratory investigation showed raised levels of white blood cell count and C-reactive protein. The MRI showed up oedema in the metatarsal heads II-IV, as well as soft tissue swelling of the forefoot without any signs of decomposition.

Because of this atypical inflammation of the forefoot a laboratory investigation to check for rheumatology disease was done and revealed borrelia burgdorferi infection. On the basis of these findings, antibiotic treatment was started and maintained over three weeks. The symptoms disappeared after 2 weeks, and the patient was able to resume his sports activities.
