Case report demonstrates blood pool SPECT/CT improves identification of knee bursitis and patellar tendinopathy.
A 63-year-old man was referred for left knee pain, with suspicion of complex regional pain syndrome. Following a normal plain radiograph, 99mTc-HDP bone scintigraphy using new 3D-ring CZT system (StarGuide) was performed. Blood pool SPECT/CT demonstrated intense hyperemia along the patellar tendon, suggesting infrapatellar bursitis, while late-phase SPECT/CT revealed focal increased uptake on the tibial tuberosity, suggestive of associated patellar tendinopathy. Our case highlights the potential of blood pool SPECT/CT using new 3D-ring CZT system to identify relevant extraosseous conditions such as knee bursitis.
