Meniscal Cyst

Today I want to show you the case of a patient that comes to me for an ultrasound examination of a palpable mass adjacent to the postero-medial compartment of the knee joint, with an history of a major knee inury five years before; the sonographic findings reveal a well defined cystic lesion and associated meniscal tear.

Always ask for an Mri investigation to better evaluate the real extent of the meniscal tear; don’t trust only ultrasound!

The Mri exam perfectly depicts the cyst and the meniscal complex tear with gross mucoid degeneration.
