title: Isolated Rheumatoid Nodule of the Achilles.
abstract: Approximately 20% to 25% of patients with rheumatoid arthritis have rheumatoid nodules. These nodules most commonly involve the soft tissues of the upper extremity, particularly adjacent to the olecranon. We present an uncommon case of a solitary rheumatoid nodule arising from the paratenon of the Achilles tendon with ultrasound and magnetic resonance images.
