Case in brief
A 33-year-old man with a nonhealing wound after pilonidal sinus excision presented for pelvic MRI due to delayed healing. The MRI revealed extensive signal loss and distortion in the sacrococcygeal region, obscuring anatomical structures. Following debridement of the wound, a follow-up MRI identified an anal fistula. The patient underwent fistula surgery, resulting in satisfactory wound healing.
What made this case unusual
The case highlights the potential for silver-containing dressings to cause MRI susceptibility artifacts, which can obscure critical anatomical details in chronic wound management.
Diagnostic / clinical pearl
Clinicians should be aware that prolonged use of silver-containing dressings may lead to imaging artifacts on MRI, complicating the evaluation of chronic wounds.
Why it matters
Understanding the impact of silver dressings on MRI can improve diagnostic accuracy and patient management in cases of chronic wounds, ensuring appropriate interventions are undertaken.
