title: Non-communicating intramuscular ganglia.
abstract: Intramuscular ganglia are rare. Most of the previously reported cases were connected with an adjacent joint. We present the imaging findings in three patients who had intramuscular ganglia that were not connected with a joint. Magnetic resonance showed a septated, encapsulated mass that was isoor hypointense to muscle on T1-weighted and hyperintense on T2-weighted images. A post-contrast T1-weighted scan in one patient showed minimal capsular enhancement. Ultrasound performed in one case showed an encapsulated, anechoic mass.
