Sonographic Differentiation Between Angiolipomas and Superficial Lipomas

Abstract

Sonography might help differentiate angiolipomas from superficial lipomas.

Sonographic appearance of a large lipoma of the spermatic cord presenting clinically as an inguinoscrotal hernia

“…as the differential diagnosis of a large groin mass, includes benign neoplasms of the spermatic cord such as ICLs, fibroma, leiomyoma, hemangioma, cystadenoma, and malignant neoplasms including liposarcoma, leiomyosarcoma, and fibrosarcoma. 7 On ultrasound, a benign fatty mass shows multiple characteristic internal echogenic strands 8 and no or minimal color doppler flow signals. Benign tumors are usually well‐circumscribed, homogeneous and hypoechoic on ultrasound.…”

Utility of High-Resolution Ultrasonography by Using Acoustic Coupler in Dermatology

“…They indicated that the differences were statistically significant [20]. In addition to these appearances, with respect to the presence of vascularity, tumor length, and tumor width, the difference was detected with statistical significance [20].…”

“…They prefer use of a copious amount of gel rather than a standoff pad. Shin et al [20] mentioned that minimal transducer pressure was exerted while maintaining good contact and using a generous amount of gel to avoid underestimation of the blood flow on Doppler study.…”

“…Angiolipma usually indicates the noninfiltrating form affecting the subcutaneous layer [20]. They are also regarded as reactive or hamartomatous lesions because they typically have a normal karyotype [20,29]. Angiolipma can be painful and are one of the varieties of lipomas.…”

“…The author has previously noted that angiolipoma is considered as one of the painful cutaneous and subcutaneous tumors accompanied with vascularized appearance using high-resolution ultrasound in dermatology [15]. Angiolipoma also tends to be smaller than 20 mm [20]. Choong et al [32] reported that subcutaneous angiolipoma represented well-defined, predominantly hyperechoic masses containing small, patchy, hypoechoic areas on gray-scale US and showed a sparse internal vasculature on color Doppler US.…”
