[12] CT scanning does expose the patient to radiation but provides better bony detail to evaluate possible bony deformity causing possible tendon dysfunction. MRI of an Intratendinous Ganglion Cyst of the Peroneus Brevis Tendon. 39, No. A single peroneal tendon (red arrowhead) is seen posterior to the lateral malleolus and the second peroneal tendon (red arrow) is dislocated lateral to the fibula. The periosteum (blue arrowheads) is partially stripped and thickened, forming a false pouch which may be filled with fluid or edema (purple arrow). The diagnosis of dislocation of the peroneal tendons is made when either or both tendons are not identified in their normal anatomic positions posterior to the lateral malleolus and the diagnosis of complete tendon rupture and retraction is excluded.
