Abstract
High resolution musculoskeletal ultrasonography has been a comprehensive tool for differentiation of soft tissue mass. However, it is not commonly used as a standard examination in the diagnosis of an aneurysm. We present a case of a growing mass in the medial aspect of the left thigh status post internal fixation of periprosthetic fracture. Initial examination with a 10 MHz linear array probe revealed a blurred hypoechoic lesion at a depth of 5 cm. After switching to a 7.5 MHz curve-linear array probe, we found a well-defined, ovoid, hypoechoic cystic lesion with posterior enhancement. In color Doppler mode, a half-blue/half-red swirling signal inside the lesion with pulsation was noted. Angiography showed an aneurysm of the left deep femoral artery with extravasation. After trans-artery embolization and debridement, the symptom of left thigh swelling improved. We conclude that the key to accurate diagnosis of this case is proper application of probes of various array and frequency, and Doppler mode.
