Use of contrast-enhanced computed tomography for management of a late-onset spontaneous massive chest wall hematoma.

This is a rare case of a 68-year-old woman who was rehospitalized after uneventful redo double-valve surgery. An 8.3 × 12.9 × 16.4 cm tense right chest wall hematoma was diagnosed. This was precipitated by a single cough. Contrast-enhanced computed tomography revealed a bleeding source. Hematoma evacuation and hemostasis following emergency warfarin reversal produced an excellent outcome.
