Abstract
Objective The purpose of our study was to demonstrate
metabolic patterns on 18F-fluorodeoxyglucose positron
emission tomography/computed tomography (18F-FDG
PET/CT) in patients with adhesive capsulitis (AC).
Methods We retrospectively reviewed 18F-FDG PET/CT
performed on 22 shoulders of 21 patients diagnosed with
AC: 2 shoulders with stage I, 14 with stage II, and 6 with
stage III. A clinical diagnosis of AC was retrospectively
made based on clinical examination, clinical course, and
imaging. The pattern of radiotracer uptake was analyzed.
Standardized uptake values in rotator interval (RI), anterior
joint capsule (AJC), axillary recess (AR), and greater
tuberosity were measured and compared to those of the
contralateral side and the control group consisting of 40
shoulders in 20 subjects without shoulder pain.
Results Four patterns of uptake were noted: (1) glenoid
type I (n = 16), with uptake in RI, AJC, and AR; (2)
glenoid type II (n = 2),with uptake in AJC and AR; (3)
glenoid type III (n = 2), with uptake in RI and AJC; (4)
focal type (n = 2), with uptake in RI or AR. Affected side
SUVmax for RI, AJC, and AR was significantly higher
compared with the unaffected side and the control group.
Two shoulders with stage I AC had patterns similar to the
ones with stage II or III.
Conclusion Specific patterns of 18F-FDG uptake with
dominant uptake in RI, AJC, or AR may be related to AC.
