Overview
Lymphatic filariasis must be differentiated from other causes of lower limb edema, such as chronic venous insufficiency, acute deep venous thrombosis, lipedema, myxedema, cellulitis and causes of generalized edema. Hydrocele sholud be differentiated from other causes of testicular masses. Breast lymphedema must be differentiated from breast cancer.
Differentiating filariasis from other diseases
Lymphatic filariasis must be differentiated from other causes of lower limb edema like chronic venous insufficiency, acute deep venous thrombosis, lipedema, myxedema, cellulitis and causes of generalized edema.

Preparing Blood Smears Thick Smears Thick smears consist of a thick layer of dehemoglobinized (lysed) red blood cells (RBCs).Thick smears allow a more efficient detection of parasites (increased sensitivity). Thin Smears Thin smears consist of blood spread in a layer such that the thickness decrease. By the ultrasound, the following findings can be observed:
|
| Chronic venous insufficiency |
|
Chronic | + | - | Bilateral | +
(If congenial) |
- |
|
Duplex ultrasound will demonstrate typical findings of venous valvular insufficiency |
| Acute deep venous thrombosis |
|
Acute | + | - | Unilateral | - | May be associated with primary disease mandates recumbency for long duration |
|
|
| Lipedema | Family history especially in women; X-linked dominant or autosomal dominant condition[2] Abnormal deposition of fat and edema and easy bruising. | Chronic | + | - | Bilateral | - | - | Tender with palpation
Negative Semmer sign to differentiate from liphedema;[3] (pinching) the skin on the upper surface of the toes. If it t is possible to grasp a thin fold of tissue the it is negative result. In a positive result, it is only possible to grasp a lump of tissue. |
MRI offers strong qualitative and quantitative parameters in the diagnosis of lipedema [4] |
| Myxedema |
|
Chronic | + | - | Bilateral | - | + |
|

| (Cellulitis-erysipelas-skin abscess) | Acute painful swelling and may be fever | Acute | + | + | Unilateral | - | - |
|
|
| Other causes of generalized edema | History of chronic general condition(cardiac-liver-renal) | Chronic | - | - | Bilateral | - | + | According to the primary cause ( Echo- LFT- RFT) | |
