Medial meniscal cyst imitating a tumor, with compression of the saphenous nerve. 1998

F Widmer, and J C Gerster
Department of Orthopedics, Hospital, Lausanne, Switzerland.

We report a case of large medial meniscal cyst responsible for symptomatic saphenous nerve compression in a 49-year-old male with a history of mild trauma to the affected knee. We are not aware of any similar cases in the literature. The lesion was delineated by ultrasonography and even more clearly by magnetic resonance imaging. At surgery, the saphenous nerve was seen to be displaced by the cyst. Cystectomy and partial meniscectomy were performed. The outcome was favorable.

D008279 Magnetic Resonance Imaging Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009408 Nerve Compression Syndromes Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.

D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
