Soft tissue layers from superficial to deep include: epidermis, dermis, subcutaneous tissue (hypodermis), fascia, muscle, bone (MP4 629 kb) Video 15.2. Adipose tissue plays multiple and complex roles not only in mechanical cushioning and energy storage but also as an important secretory organ that regulates energy balance and homeostasis multilaterally. A wide variety of superficial soft-tissue masses may be seen in clinical practice, but a systematic approach can help achieve a definitive diagnosis or limit a differential diagnosis. The two most common venous Doppler ultrasound features in our study were multiple inguinal lymphadenopathy 82 (35.7%) and edema of the skin and subcutaneous layers 67 (29.1%), respectively (Fig. cross-sectional imaging (CT and MR) is helpful in differentiation between superficial and deep components of cellulitis. 3.

Active synovitis overlying a large metacarpal head erosion. Edema is an accumulation of fluid in the interstitial space that occurs as the capillary filtration exceeds the limits of lymphatic drainage, producing noticeable clinical signs and symptoms. In cases with lymphedema there is thickening of all the cutaneous layers, hypoechogenicity of the dermis, and increased echogenicity of the subcutaneous tissue in addition to the anechoic fluid between the fatty lobules of the hypodermis.8,9 It is defined as swelling caused by an increase in interstitial fluid that exceeds the capacity of physiologic lymphatic drainage. edema.
