Case in brief
A 52-year-old woman with chronic left lateral foot pain was referred for evaluation of a suspected stress fracture. Technetium-99m HDP bone scintigraphy with a 3D-ring CZT system showed increased uptake on blood-pool and late-phase SPECT/CT in foci corresponding to the os peroneum. These findings suggested painful os peroneum syndrome (POPS), rather than the suspected stress fracture.
What made this case unusual
Blood-pool and late-phase imaging with a 3D-ring CZT SPECT/CT system localized increased uptake to the os peroneum in a patient referred for suspected stress fracture.
Diagnostic / clinical pearl
In chronic lateral foot pain, uptake localized to the os peroneum on blood-pool and late-phase SPECT/CT can support POPS as a diagnostic consideration.
Why it matters
The report notes that early diagnosis of POPS is important for adequate management.
