Sweet Syndrome Masquerading as Central Venous Port Infection: An IR M&M Lesson

A 'Lessons in IR' M&M case highlights Sweet syndrome — an acute febrile neutrophilic dermatosis — mimicking central venous port infection, underscoring that not all port-site inflammation is infectious. Rare but important diagnostic pitfall for IR teams.

• Case-based M&M format from JVIR's 'Lessons in IR' series; exact sample size not reported in source — likely a single case or small series.
• Sweet syndrome can present with erythema, tenderness, and systemic inflammation at or near a port site, closely resembling device infection; misdiagnosis risks unnecessary port removal and delayed steroid therapy.
• Key limitation: single-case or anecdotal design limits generalizability; incidence and distinguishing imaging features not quantified in the available abstract.
