Purpose: To identify clinical and radiologic risk factors for recurrence of patellar dislocation after a first episode.

Extrapulmonary Tuberculosis: Pathophysiology and Imaging Findings.

Extrapulmonary tuberculosis (TB) represents approximately 15% of all TB infections. It is difficult to diagnose on the basis of imaging characteristics and clinical symptoms, and biopsy is required in many cases. Radiologists must be aware of the imaging findings of extrapulmonary TB to identify the condition in high-risk patients, even in the absence of active pulmonary infection.

Anatomy and pathology of the nail and subungual space: Imaging evaluation of benign lesions.

The lesions of the ungual and subungual space include various etiologies, which may be similar in clinical presentation, almost always with nail deformity. Imaging evaluation is helpful in the characterization of these lesions, narrowing the differential diagnosis and leading to appropriate treatment. This review aims to outline the anatomy and terminology used to describe the alterations of the nail unit and the main imaging characteristics of some of the most common benign lesions of the nail.
