Abstract

A 23 year-old man presented with abdominal pain after suffering blunt trauma caused by a seatbelt injury. His low platelet count of 137 × 109/L was initially attributed to trauma and underlying hypersplenism due to glucose-6-phosphate dehydrogenase (G6PD) deficiency. Despite conservative management, his platelet count remained persistently reduced even after stabilising his haemoglobin and clotting abnormalities. After a week, follow-up imaging revealed an incidental finding of a pseudoaneurysm (measuring 9mm × 8mm × 10mm)adjacent to a splenic laceration. The pseudoaneurysm was successfully closed via transcatheter glue embolisation; 20% of the spleen was also embolised. A week later, the platelet count normalised, and the patient was subsequently discharged. This case highlights the pitfalls in the detection of delayed occurrence of splenic artery pseudoaneurysm after blunt injury via routine delayed computed tomography. While splenomegaly in G6PD may be a predisposing factor for injury, a low platelet count should arouse suspicion of internal haemorrhage rather than hypersplenism.
