Abstract:
Lower extremity swelling has a broad differential diagnosis, including lymphedema, obesity-induced lymphedema, phlebolymphedema, and lipedema. Although these conditions may appear similar clinically, their pathophysiology and lymphoscintigraphic findings differ. Obesity, venous insufficiency, and abnormal adipose tissue can complicate image interpretation. We present four representative cases to illustrate characteristic imaging patterns across these conditions. These cases highlight the importance of interpreting lymphoscintigraphy in a clinical context.

This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
01:15Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
