Shoulder adhesive capsulitis in cancer patients undergoing positron emission tomography - computed tomography and the association with shoulder pain

Figure 1 Fifty-two years old patient with lung cancer. A: Initial pre-therapy Positron emission tomography - computed tomography showed no significant capsular 18F-fluorodeoxyglucose (FDG) uptake; B: After the patient was treated with chemotherapy for his lung cancer, the patient developed bilateral shoulder pain with bilateral capsular FDG uptake.

Figure 2 Fifty-six years old patient with lung cancer. Fused Positron emission tomography (PET) - computed tomography (A) and (C) maximum intensity projection (MIP) PET images demonstrate mild diffuse non-specific bilateral shoulder capsular FDG uptake at initial pre-therapy imaging (arrows, better seen on MIP images); B and D: After diagnosis of lung cancer and treatment, the patient developed right shoulder pain and more focal capsular uptake in the right shoulder capsule in the region of rotator interval (arrows).
