Unusual Presentation of Popliteal Cyst on Magnetic Resonance Imaging

Figure 1

Preoperative sagittal T1-weighted (a) and T2-weighted (b) and axial T2-weighted (c) magnetic resonance images. A cyst was detected with low signal intensity on T1-weighted images and heterogeneous intermediate signal intensity on T2-weighted images. A connecting path was seen between the cyst and the subgastrocnemius bursa (arrow), compatible with the characteristics of popliteal cyst.
