title: Leaking Baker's cyst detected by magnetic resonance imaging.
abstract: Popliteal or Baker's cysts, often found incidentally during examination of the knee, are common. The authors report the magnetic resonance imaging (MRI) manifestations of a leaking Baker's cyst that initially presented as thrombophlebitis in a patient who had undergone reconstruction of the anterior cruciate ligament 4 months before; no cyst was present at the time of the surgery. Marked inflammatory changes apparent in the surrounding muscle and subcutaneous tissues were best appreciated in T2-weighted and fat-suppressed inversion recovery images. Although the results of ultrasonography suggested the diagnosis, they were not conclusive; MRI was a useful noninvasive adjunct in making the definitive diagnosis.
