Differential Diagnosis for New Hematoma to Leg
- Single Most Likely Diagnosis
- Trauma: This is the most likely cause of a new hematoma to the leg, as it is a common consequence of injury or accident.
- Other Likely Diagnoses
- Anticoagulant use: Patients on anticoagulant medications such as warfarin, aspirin, or heparin are at increased risk of developing hematomas due to their impaired blood clotting ability.
- Vascular malformation: Abnormalities in blood vessel structure, such as arteriovenous malformations, can lead to hematoma formation.
- Hemophilia or other bleeding disorders: Individuals with inherited bleeding disorders may experience spontaneous hematoma formation due to their impaired blood clotting ability.
- Do Not Miss Diagnoses
- Deep vein thrombosis (DVT): Although less likely, DVT can cause leg hematoma and is a potentially life-threatening condition if not promptly diagnosed and treated.
- Ruptured aneurysm: A ruptured aneurysm in the leg can cause a hematoma and is a medical emergency requiring immediate attention.
- Infection (e.g., cellulitis or abscess): Infections can cause inflammation and bleeding, leading to hematoma formation, and can be life-threatening if not properly treated.
- Rare Diagnoses
- Hemangiosarcoma: A rare type of cancer that can cause hematoma formation in the leg.
- Amyloidosis: A condition characterized by the deposition of abnormal proteins in tissues, which can lead to bleeding and hematoma formation.
- Scurvy: A rare condition caused by vitamin C deficiency, which can lead to impaired blood clotting and hematoma formation.
