Increased 68Ga-FAPI Uptake in Intramuscular Gluteal Hematoma in a Patient With Hemophagocytic Syndrome.

ABSTRACT

ABSTRACT A 39-year-old man was diagnosed clinically with hemophagocytic syndrome, which was suspected to be secondary to a malignancy. Therefore, the patient underwent a 68Ga-FAPI PET/CT scan as part of an ongoing clinical trial (ChiCTR2100044131). Increased tracer uptake was noted the gluteal region. Medical history revealed recent iliac bone marrow aspiration on the same side. On further examination, the lesion was confirmed to be a hematoma. The present case highlights that puncture operations may result in intramuscular hematomas, which might potentially malignancy on a 68Ga-FAPI PET/CT.
