title: "Dry tap" during spinal anaesthesia turns out to be epidural abscess.
abstract: We report a case of "dry tap" during spinal anaesthesia in a patient posted for incision and drainage of lower limb with cellulitis. When the patient was being given sub-arachnoid block (SAB) for regional anaesthesia, it turned out to be a case of pyogenic ilio-psoas abscess extended up to the paravertebral and epidural spaces. The causative organism was Staphylococcus aureus. This is probably the first case reported when epidural abscess is diagnosed during SAB.
