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.

Purpose: The goal of this study is to assess the usefulness of ultrasonography in diagnosis of Baker's cyst. Materials and Methods: 42 cases of popliteal mass in 41 patients were reviewed between August 2006 and April 2009. All patients were evaluated with both MR imaging and ultrasonography. We investigated the comparison of a morphology, location, septation, and communication of mass between MR imaging and ultrasonography. Results: On ultrasonography, 40 Baker's cysts and 2 lipomas were detected, and all cysts were located at the medial side. 11 simple septated masses and 3 multiple cysts were detected, and 26 simple communicated cysts were suspected. On MR imaging, 40 Baker's cysts and 2 lipomas were detected, and all cysts were located at the medial side. 13 simple septated masses and 3 multiple cysts were detected, and 15 simple communicated cysts were suspected. Conclusion: Ultrasonography didn't give the definite information of Baker's cyst about communication with joint, but ultrasonography was a cost-effective useful tool for evaluation of a morphology, location and differential diagnosis of the Baker's cyst.

Fungal arthritis is a rare joint infection that occurs in immunosuppressant patient, intravenous drug abuser and long term antibiotics user, and is especially rare in a healthy adult. Two case reports of fungal arthritis have been demonstrated in the country, but those in healthy adults have not been reported yet. Here, we experienced an antifungal treatment following successful arthroscopic debridement of fungal arthritis with a popliteal cyst in a healthy adult who got repetitive intraarticular steroid injections and report the case with review of relevant literatures. Surgeons should consider the possibility of fungal arthritis although it is rare and demonstrates nonspecific clinical features.
