IGA nephropathy and spinal epidural abscess after COVID-19 infection: a case report.

A 56-year-old male admitted to the hospital for generalized weakness and fever. He was treated in hospital for 10 days due to COVID-19. He did not receive any immunosuppressive therapy during admission. One day after his discharge he experienced back pain and received analgesic therapy for 10 days. About one month later he experienced severe back pain and gross hematuria. He was admitted to hospital with acute kidney injury and new-onset lower extremity muscle weakness. His renal biopsy revealed IgA nephropathy and thoracic/cervical/lumbar-spine imaging showed an epidural abscess. This is a unique case report of a patient developing an epidural abscess and acute kidney injury together as a serious complication of COVID-19 infection.
