Recently seen in my ED:
An elderly patient is brought in by relatives. "We’re concerned about the forehead swelling". Patient has a remote history of a head injury, is pleasant and cooperative. No diabetes, otherwise pretty healthy. ROS noncontributory.
Patent had been seen by a physician the day prior, and a workup had been scheduled for the following weekday. But as this was Friday night, and concern was mounting*, though not symptoms.
Exam: Afeb, normal VS. Otherwise unremarkable excepting an area of redness with edema on the left forehead, including and just above the eyebrow. Eye not involved, no pain with eye movement, no visual changes. Reddened area feels firm, not fluctuant, and is minimally tender.
A CT scan was obtained, with the above finding(s).
Your challenge: What’s wrong? What’s the eponym?

(We see this a lot in the ED: the knowledge that ‘something is wrong, otherwise my doctor wouldn’t have ordered an MRI/ head CT/ Sono/ whatever begins to work on that anxiety center, and they come to the ED, unable to wait. Somethimes this is reasonable, mostly less-so, but when in their shoes I find it had to be too harsh about).
Answer: As several guessed, it’s Pott’s Puffy Tumor! Thanks for playing.
