The authors report a case of a solitary intramuscular cysticercosis in a 47-year-old female who presented with a mass in the right elbow for five years. The magnetic resonance imaging (MRI) findings revealed a cystic mass of 1.5 cm. in size located at the periphery of the pronator teres muscle; the T1-weighted MRI showed hypointensity mass with internal content that was more obviously seen on T2-weighted image and T1-weighted with fat suppression after gadolinium administration. The authors could not recognize peri- lesional edema in the MRI that corresponded with the histological findings of chronic inflammatory process in combination with foreign body giant cell reaction. The scolex could not be seen in the imaging but could be identified in the histopathological sections.
