Synovial cyst. Same patient as in Fig. 3. Coronal fat-suppressed T2-WI (a) and sagittal T1-WI (b): well-circumscribed, bilobar lesion (asterisk) with high signal intensity (SI) on T2-WI and low SI on T1-WI. The smaller “lobe” (long arrow) extends caudally towards the posterior facet of the subtalar joint. The cyst causes displacement of the small saphenous vein (short arrow)
