Introduction: Effective critical care requires the placement of a central venous catheter (CVC), which is frequently indicated for volume resuscitation, hemodynamic assessment, and the administration of vasopressors, blood products, and parenteral nourishment. However, central venous catheterization is not without its complications. The majority of these problems are avoidable and treatable with proper patient selection, cautious insertion technique, and attention after catheter insertion.

Case: We present a case of a 34-year-old male patient who developed unilateral hydrothorax as a result of a central venous catheter malposition in the lung parenchyma. The condition was resolved since the complication was identified and treated quickly.

Conclusion: Previous studies have revealed a few unusual incidences of catheter misplacement. This case report can be serviceable to the medical community as they should be aware of this unique presentation, it’s management and outcome.
