Differential Diagnosis for Palpable Cord Leg
- Single most likely diagnosis
- Deep Vein Thrombosis (DVT): This is the most likely diagnosis due to the presentation of a palpable cord in the leg, which is a classic sign of DVT. The cord-like structure felt is often a thrombosed vein.
- Other Likely diagnoses
- Varicose veins: These can sometimes feel like cords under the skin, especially if they are large and tortuous.
- Superficial thrombophlebitis: Inflammation of a superficial vein can cause it to feel like a cord.
- Lymphedema: While not typically described as a cord, in some cases, the swelling and fibrosis associated with lymphedema can cause the skin and underlying tissues to feel firm and cord-like.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Popliteal artery aneurysm: Although less common, a palpable mass in the popliteal fossa could be an aneurysm, which is a serious condition requiring prompt intervention.
- Malignancy (e.g., soft tissue sarcoma): Rarely, a palpable cord could be a sign of a malignant process, such as a soft tissue sarcoma.
- Rare diagnoses
- Thrombophlebitis of a superficial vein with significant inflammation and scarring, leading to a cord-like feeling.
- Chronic venous insufficiency with significant fibrosis and scarring, potentially feeling like a cord.
- A congenital or acquired vascular malformation that presents as a palpable cord.
