The Special K Constellation, a Rare Presentation of Ketamine Use: A Case Report.

Ketamine is commonly used in the emergency medicine setting, but also as a recreational drug. There have been many animal studies investigating ketamine, but little data on long-term clinical use of ketamine in humans. In this case presentation, a 22-year-old international male student presented with crepitus and cachexia and was found to have extensive subcutaneous emphysema, pneumorrhachis/intraspinal air, pneumomediastinum, and multiorgan failure. In this case report, we discuss how ketamine abuse is the likely cause of these findings.
