a, b. Baker’s cyst in a 33-year-old man presenting with nonspecific intermittent knee pain. Sagittal FS PD-weighted MRI (a) shows a hyperintense multiloculated fluid collection surrounding the medial gastrocnemius tendon. Its typical emergence between the medial head of the gastrocnemius muscle and the semimembranosus tendon is more evident on the axial view (b), as well as an intramuscular extension in its lateral aspect (arrow). MGc, medial gastrocnemius; Sm, semimembranosus
