Histologic Base of Mild 18F-FDG Uptake in Simple Bone Cyst of Adult Rib: A Case Report with Multi-image Correlation / 핵의학분자영상

ABSTRACT

Simple bone cyst (SBC) is very rare in adult ribs. The diagnosis basically relies on conventional radiography and occasionally on CT. There has been no earlier publication on PET/CT diagnosis of SBC. We report a case of adult costal SBC diagnosed by positive 18F-fluorodeoxyglucose (FDG) uptake. Histology showed the FDG uptake to be associated with reactive woven bone formation and nonspecific chronic inflammation. Correlation of PET, CT, plain radiography and sonography are also described.
