Late diagnosis of a lateral abdominal wall hematoma presenting with nonspecific findings: report of a case.

We report a case with a late diagnosis of posttraumatic lateral abdominal wall hematoma. The patient was admitted with a giant hematoma presenting with pleural effusion, anemia and weight loss on postoperative 30th day after a blunt trauma. Computerized tomography analysis revealed a hematoma extending from axilla to the gluteus. Fine-needle aspiration revealed an exudative fluid and five liters of fluid collection was drained. Misdiagnosed lateral abdominal wall hematomas can be diagnosed with nonspecific findings as in this case.
