Early Bone Infarction With Soft-tissue Abscess.

Early bone infarction was rarely reported, and additional research is needed for diagnosis and treatment. This article aims to report the diagnosis and treatment process of a patient with unexplained early bone infarction with soft-tissue abscess and a review of related literature. A 52-year-old male patient with early bone infarction of unknown etiology and soft-tissue abscess was analyzed retrospectively. He sustained right thigh swelling and pain for 5 days and hip and knee joint dysfunction, accompanied by fever, temperature 38°C, no limb numbness, sensory disturbance, and other discomfort. On MR images, early bone infarction with local soft-tissue abscess was found. After incision and drainage of soft-tissue abscess, wound débridement, and suture, the swelling and pain of the affected limb dysfunction gradually recovered. Early bone infarction of unknown etiology with soft-tissue abscess has a low incidence. MRI is the main imaging diagnostic method. Conservative treatment is the main guard against malignant changes and surgical treatment, if necessary.
