case_images: Ultrasound examination revealed a polycystic hematoma in the forearm flexors (long axis section of the hematoma; (A). The hematoma was located between the median nerve (*), and radius-ulna (short axis section of the hematoma; (B). Three days after drainage and urokinase lavage, ultrasonography showed that the hematoma nearly disappeared (C). Hematoma did not recur at the 4-month follow-up after treatment (D).
