Insights
A large hip joint cyst mimicked deep venous thrombosis by compressing the femoral vein. Prompt diagnosis and treatment resolved the patient's leg swelling and pain.
Area of Science:
- Orthopedics
- Vascular Surgery
- Radiology
Background:
- Deep venous thrombosis (DVT) is a common cause of leg swelling.
- Femoral vein compression can present with DVT-like symptoms.
- Hip joint pathology can rarely cause extrinsic vascular compression.
Observation:
- A patient presented with clinical signs suggestive of DVT.
- Diagnostic imaging revealed a large hip joint cyst compressing the femoral vein, without evidence of thrombus.
- The cyst was identified as the cause of venous obstruction.
Findings:
- The patient's symptoms were attributed to extrinsic compression of the femoral vein by a hip joint cyst.
- Non-thrombotic femoral vein compression can mimic DVT.
- Successful management involved addressing the underlying cystic lesion.
Implications:
- This case highlights the importance of considering rare causes of venous compression.
- Accurate diagnostic imaging is crucial for differentiating DVT from extrinsic compression.
- Understanding the differential diagnosis for leg swelling is essential for effective patient management.
Abstract:
A patient is presented with signs mimicking deep venous thrombosis of the leg, which proved to be compression of the femoral vein, without thrombosis, caused by a large cyst from the adjacent hip joint. Clinical presentation, diagnostic imaging procedures and therapy are presented with a review of the literature.
