Computed tomography of traumatic serosanguineous cysts.
Two patients developed traumatic peripelvic serosanguineous cysts, following pelvic fracture. A serosanguineous cyst develops when shearing forces cause separation of the skin and subcutaneous fat from the deep fascia and muscle. The space thus created is filled with serious fluid and blood, and clinically presents as soft cystic masses, appearing usually within a day or so, or rarely, after several weeks or months. Most of these lesions resolve spontaneously, or following aspiration; however, some may persist, necessitating surgical resection. Computed tomography is the modality of choice for detection and, in those cysts requiring surgery, it is helpful in revealing the exact size and location of these lesions.
