It also highlights the fact that ultrasound is the imaging method of choice when retained FB are clinically suspected. In stage 1 lipedema, swelling reverses with leg elevation.
1) found that PLS edema occurred more frequently and more severely in overweight patients. FIGURE 1. The swelling disappeared on antibiotic treatment. As in other areas of musculoskeletal imaging the two techniques are complementary and both may be employed in any individual case.
However all of these cases showed substantial evidence of characteristic muscle damage on imaging modalities (9,11,12,15,18). Definition (MSH) Abnormal fluid accumulation in TISSUES or body cavities. Other associated findings include scrotal wall edema and epididymal enlargement.

Recovery was uncomplicated, with complete resolution of symptoms within 48 hours in all 3 patients. VLU can be defined as a full-thickness defect of the skin frequently seen in the ankle region that fails to heal spontaneously and is sustained by chronic venous disease (CVD, the spectrum of venous diseases affecting the lower limbs) [].In more recent guidelines, a VLU is defined by best practice and uses the standard definition of an open . Lymphoedema is the swelling, particularly in subcutaneous tissues, that results from the obstruction of lymphatic vessels or lymph nodes, and it involves the accumulation of lymph in the affected region. . B. Ultrasound with color Doppler also reveals ill-defined hypoechoic fluid collection with heterogeneous content within site of inflammation.

It is important to address this swelling in each stage of lipedema. 1 Lymphoedema is caused by abnormalities or diseases originating in the lymphatic system either from congenital or acquired conditions or surgical lymph node excision. Seen between 14 and 18 weeks gestational age (at 18-20 weeks measurement of nuchal thickness becomes unreliable due to the wide range in the normal rate of development of the fetal neck muscles and subcutaneous tissue). A lipoma- a benign collection of fat cells. Fat tissue is categorized into subcutaneous fat tissue (SCAT) or visceral fat tissue (VSA) depending on its distribution, with the two having different metabolic functions. 1. A hyperechoic diffuse swelling of the subcutaneous tissues of the affected region can also on occasions be noted . In most cases it occurs when fluid accumulates in subcutaneous tissues leading to volume expansion, although congenital etiologies and lipedema may result in excessive soft tissue in the lower extremities. Studies reviewing the role of venous Doppler ultrasound in unilateral lower limb swelling have reported an association with inguinal . There are also extensive subcutaneous small fluid collections consistent with subcutaneous edema/cellulitis Ultrasound (US) is frequently used for evaluating inflammation of subcutaneous tissue caused by pressure ulcers (PUs), but color Doppler mode (CDM) helps to better identify inflammatory edema in subcutaneous fat and necrotic tissue in PUs. 5.

In most peripheral and superficial lesions ultrasound provides all the information required. A small painless soft lump near the rib cage with a normal ultrasound scan is suggestive of a skin or subcutaneous tissue swelling. 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. We can find increased fluid content within tendon sheath, a thickening of the synovial sheath, peritendinous subcutaneous edema resulting in a hypoechoic halo sign and peritendinous subcutaneous hyperemia on Doppler imaging.
