technetium-tc-99m-medronate and Synovitis--Pigmented-Villonodular

Pigmented villonodular synovitis (PVNS) is a rare proliferative synovial benign disorder, which is characterized by villonodular hyperplasia of joints, tendon sheath, and synovium; invasion of adjacent tissue; and sometimes visible hemosiderin deposition. Studies regarding bone scan findings of PVNS were relatively limited. Here, we report our findings on 99mTc-MDP 3-phase bone scan with SPECT/CT images on delayed phase in 3 patients with joint PVNS.

Pigmented villonodular synovitis (PVNS) is a proliferative disorder of unknown etiology that originates from the synovial membranes of joints. Some PVNS lesions have been misdiagnosed as malignancy due to their tumorlike imaging findings. There are few reports of PVNS on nuclear 3-phase bone imaging. However, 3-phase Tc-MDP bone scan can offer additional information about the dynamic flow features of the lesion, which may do help in differential benign and malignant. The present report describes 3-phase bone imaging in a surgically proven case of PVNS with tumorlike appearance and atypical location.
