Pseudotumoural

soft tissue lesions of the foot and ankle: a pictorial review. Synovial cyst. A 34-year-old female patient with lateral foot pain and soft tissue mass posterior to the lateral malleolus. Ultrasound examination in the paracoronal (a) and coronal plane (b) demonstrates a well-circumscribed, bilobular, mostly anechogenic lesion (asterisk) with posterior acoustic enhancement, correlating with a cystic nature. Some echogenic debris is present in the dependent part of the lesion. The lesion causes displacement of the sural nerve (arrowheads), causing lateral foot pain

Pseudotumoural

soft tissue lesions of the foot and ankle: a pictorial review. 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)

Intraspinale

Synovialiszyste, die in Kombination mit anderen degenerativen Frakturen zu einer hochgradigen Spinalkanalstenose führt. Links STIR sagittal, Mitte STIR koronar, rechts T2 axial.

Pseudotumoural

soft tissue lesions of the hand and wrist: a pictorial review. Small cyst (maximum longitudinal size between calliper measurements) at the dorsal aspect of the distal interphalangeal (DIP) joint in a patient with osteoarthritis. Note a small connecting stalk to the adjacent DIP joint (arrow). Longitudinal ultrasound
