Learning objectives

To describe clinical, technicaland imaging featuresof "retained needle disease".

Background

Prompt retained needleslocalization and removal are recommended as the consequence of needles’ harmful potential related to their prickly shape; in this scenario needlesidentification could be a real challenge for the radiologist, because of their relatively poor conspicuity and small dimension.

Findings and procedure details

ANAMNESTIC AND CLINICAL EVALUATION Knowledge of needles' shape, dimension and material, as well as reconstruction of clinical history, is important to set the most appropriate diagnostic workup. According to the mechanism of retention three possible patterns are distinguishable: ingestion, iatrogenic retention and penetration [1]. Ingestion Ingestion is a rare event, more common in children than in adults. A special attention is required for particular categories: patients with behavioral or mental disorders, or healthy adults and children with predisposing factors or injurious situational problems (drugs abuse,...

Conclusion

A detailed anamnestic evaluation together with multimodality imaging techniques and familiarity with imaging findings provide an important advantages in making diagnosis of "retained needle disease".
