This led us to go for a thorough skeletal survey, which showed the involvement of the left femur and tibia (Fig. 1).
Magnetic resonance images (axial and coronal) showing multiple well-defined lesions, hyperintense on T2 and STIR images, largest lesion seen in distal thigh, measuring 51 mm x 48 mm x 73 mm.

She was also evaluated with magnetic resonance imaging (MRI) of whole of the thigh which showed two additional soft tissue masses; one in left mid-thigh and the other in the left inguinal region (Fig. 2).
Single, encapsulated globular mass excised from distal thigh measuring 8 cm x 4 cm x 3 cm and weighing 88 g.

A single, globular, pale white, encapsulated nodular mass measuring 8 cm x 4 cm x 3 cm was excised (Fig. 3).
Histopathological examination showed a well-encapsulated tumor with myxoid background containing many interspersed stellate to spindle-shaped cells with scant to moderate amounts of cytoplasm.

Histopathological examination was suggestive of intramuscular myxoma (Fig. 4).
Magnetic resonance images (axial and coronal) at 6 months showing initial increase in the inguinal and thigh lesion.

On follow-up, MRI was done 6 months postoperatively, and these two masses seemed to have slightly increased in size; however, the patient remained asymptomatic (Fig. 5).
Magnetic resonance images at 2 years' followup showing decrease in the size of the thigh lesion and the minimal increase in the size of the inguinal lesion.

At latest follow-up after 2 years, the patient was pain free with no recurrence and the MRI showed decrease in the size of the mid-thigh lesion and minimal increase in the size of the left inguinal lesion (Fig. 6).
