Abstract
Objective Because positron emission tomography/computed
tomography (PET/CT) using fluorine-18-fluorodeoxyglucose
(18F-FDG) can be used to visualize inflammation
of the musculoskeletal system, it may help elucidate
the pathophysiology of frozen shoulder (FS). The purpose
of this study was to characterize the uptake pattern on 18FFDG
PET/CT in patients with idiopathic FS and to determine
if there is a correlation between its metabolic parameters
and clinical findings.
Methods 18F-FDG PET/CT was conducted to 35 patients
with unilateral idiopathic FS. Clinical data including pain,
functional scores, and passive range of motion (ROM) were
collected. Maximum standardized uptake values (SUVmax)
were measured at the four regions of interest (ROIs): rotator interval (RI), anterior joint capsule (AJC), axillary
recess (AR), and posterior joint capsule (PJC) from the
attenuation-corrected axial images.
Results Mean SUVmax values for four ROIs of the
affected shoulder were significantly higher than those of
the unaffected shoulder. Mean SUVmax values of RI and
AR were significantly higher than those of AJC and PJC
and mean SUVmax of AJC was significantly higher than
that of PJC in the affected side. Three recognizable patterns
of increased uptake were noted: (1) AR dominant type (15
patients); (2) RI dominant type (9 patients); (3) both RI
and AR dominant type (11 patients). The SUVmax of AR
showed negative correlation with abduction and forward
flexion. The SUVmax of RI showed negative correlation
with external rotation and internal rotation. The SUVmax
of AJC showed negative correlation with all ROMs. However,
there was no significant correlation between the SUVmax
of PJC and any ROM.
Conclusion Our study demonstrates that the anterior–
inferior capsular portion, including RI and AR, is the main
pathologic site of idiopathic FS and reveals significant correlations
between ROM and metabolic parameters on 18FFDG
PET/CT. These results imply that AR and RI lesions
are related to elevational limitations and rotational limitations,
respectively.
