Intramuscular Cysts at the Proximal Calf: Two Case Reports and a Systematic Review of Literature
Bibliographic record
Abstract
Intramuscular cysts at the proximal calf are rare; however, their etiology is diverse, making accurate diagnosis and treatment difficult. To our knowledge, there are no previous publications in literature about intramuscular cysts at the proximal calf, arising from different origins. This article describes two rare cases with intramuscular cysts. Case 1 was diagnosed as an intramuscular ganglion cyst arising from the proximal gastrocnemius medialis muscle, and arthroscopic examination as well as open cyst excision was performed. Case 2 was another type, which has never been reported in the literature. It was diagnosed as diffuse pigmented villonodular synovitis (PVNS), with the intramuscular cyst arising from PVNS, and only arthroscopic synovectomy was performed. The diagnoses for these cases were confirmed by histopathology. In addition, we have summarized intramuscular cysts at the proximal calf by a systematic literature review and divided them into five types based on their origin. The five types are, intramuscular cysts arising from the muscular tissue, knee joint, proximal tibiofibular joint, the neurilemma and PVNS. The treatment of intramuscular cysts varies based on their origin; hence, it is important to identify the origin. J Med Cases. 2018;9(2):45-51 doi: https://doi.org/10.14740/jmc2984w

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
