Other Studies:
Right foot Xray 3 views (on admission): No evidence of fracture, dislocation or other significant abnormality. Case Photo #1 Case Photo #2
Right foot MRI w and w/o contrast (hospital day 2): Prominent increased signal most prominently involving the abductor digiti minimi muscle laterally and to a lesser extent the abductor hallucis muscle medially. No discrete drainable fluid collections identified. There is also likely reactive marrow edema involving the calcaneus. Case Photo #3
CT scan w/o contrast (hospital day 4): Focal fluid collection adjacent to the plantar and lateral aspect of the calcaneus and cuboid measuring approximately 5 x 4 x 2 cm. No CT evidence for osteomyelitis. Case Photo #4
Consultations:
Orthopedics: unlikely septic arthritis
Rheumatology: recommended CT that was done above, recommended trial of prednisone 60mg before CT was done to see if inflammatory process causing pain.
