RESUMO
A man in his 50s with diabetes presented with backache, left flank pain and fever. On evaluation, he was found to have emphysematous pyelonephritis of the left kidney with a paranephric abscess extending into the posterior abdominal wall and superiorly up to the posterior chest wall and inferiorly extending up to the posterior superior iliac spine. The management involved the initiation of broad-spectrum antibiotics and percutaneous drainage of the abscess. However, as he continued to worsen symptoms-wise, he underwent computed-enhanced CT of the abdomen and thorax. The imaging revealed the presence of a purulent collection in the left lumbar region with an extension along the posterior cervical region and the retropharyngeal space. He underwent a fasciotomy of the lumbar region. The occurrence of emphysematous pyelonephritis along with necrotising fasciitis is uncommon and requires early aggressive management with broad-spectrum antibiotics and adequate drainage. This emphasises the need for early reimaging if the patient does not settle with antibiotics or percutaneous drainage.
