This review covers imaging for lower extremity infections, detailing anatomical considerations and the use of various imaging modalities. It highlights key imaging features for differentiating infectious from non-infectious causes of swelling.
Area of Science:
- Radiology
- Infectious Diseases
- Anatomy
Background:
- Imaging is crucial for diagnosing and managing lower extremity infections.
- Accurate diagnosis requires understanding lower extremity anatomy.
Purpose of the Study:
- To review the role of imaging in lower extremity infections.
- To illustrate relevant anatomy and diagnostic imaging features.
- To differentiate infectious from non-infectious causes of swelling.
Main Methods:
- Review of imaging modalities including plain radiographs, CT, US, MRI, and nuclear medicine.
- Discussion of imaging features for specific infections.
- Comparison with non-infectious conditions.
Main Results:
- Detailed imaging features for cellulitis, abscess, necrotizing soft tissue infection, pyomyositis, tenosynovitis, septic arthritis, and osteomyelitis are presented.
- Differentiating characteristics between infectious and non-infectious etiologies are discussed.
Conclusions:
- Various imaging techniques are essential for the comprehensive evaluation of lower extremity infections.
- Understanding specific imaging findings aids in accurate diagnosis and treatment planning.

Veins of Lower Limbs
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...
