Sterile abscess formation following a corticosteroid injection for the treatment of plantar fasciitis.

Abstract

A sterile abscess following a corticosteroid injection for the treatment of plantar fasciitis has not been reported in the literature. This case report demonstrates such a complication. A 45-year-old man presented with pain, erythemia, edema, and increased warmth to his left foot after 2 cortisone injections into his left heel over a 2-month period for plantar fasciitis. The symptoms began shortly after the second injection and after a 10-day course of oral antibiotics, the condition slowly worsened. A computerized axial tomography scan was suggestive of an abscess. Following incision and drainage, cultures that were taken during the surgical procedure did not produce any organism, prompting a diagnosis of a sterile abscess. The patient was discharged home and recovered from the abscess without reoccurrence or further surgical intervention.
