We report the case of an 8-year-old boy with no prior abnormal bleeding history who presented with severe central abdominal pain following a freak accident at a local ice rink. Clinical examination confirmed a tender periumbilical mass. An ultrasound scan confirmed a large haemorrhagic fluid collection adjacent to the second part of his duodenum that was causing a subacute small-bowel obstruction. He was found to have a persistently prolonged prothrombin time between 17.3 and 18.1 s but normal liver function tests. There was no suggestion of dietary vitamin K deficiency. Further investigations confirmed factor VII deficiency with levels between 30.4 and 33.6 IU dL-1. His prothrombin time did not normalize with intravenous vitamin K. He was subsequently treated with three 30 microg kg-1 body weight doses of novoseven at 4-h interval and made an excellent recovery. The haematoma virtually resolved completely confirmed by a follow-up ultrasound scan 3 months after the initial event.
