Abstract

Baker's cyst is found as most frequent cystic mass around the knee occurring between medial head of gastrocnemius muscle and semimembranosus muscle. The proximal or posterolateral extension of the cyst had been rarely reported and the cyst into the surrounding muscular tissue extremely rare. Intramuscular Baker's cyst that we report was found between lateral head of gastrocnemius muscle and popliteus tendon, and then extended into the plantaris muscle. With review of the literature, we here report a very rare case of plantaris muscular extension of Baker's cyst.

Keywords: plantaris muscle, Baker's cyst

Figures and Tables

Figure 1
Multiseptated cystic mass (arrow) between lateral head of gastrocnemius and popliteus was seen with high intensity signal in the sagittal T2 weighted scan (A, B) and axial T2 weighted scan (C).

Figure 2
Infiltration of cystic mass was found along the plantaris.

Figure 3
Plantaris was detached from its origin, and tenotomy was done at mid leg level for total removal.

Figure 4
Microscopic finding (×100) of the cyst with H&E stain shows with plantaris muscle fibers (A). On high power field (×400), the synovial lining (arrow) in the cyst wall was seen (B).
