Herein, we report a rare case of subcutaneous sparganosis in a 60‐year‐old Japanese woman. She had a 2 cm × 2 cm elastic‐hard, subcutaneous nodule, which was the larva of a tapeworm, and a surrounding granuloma in her internal thigh. It was thought that she became infected by drinking water contaminated with the worm. She was definitively diagnosed by enzyme‐linked immunosorbent assay (ELISA). After excision of the lesion, the titer of ELISA showed clear decline; therefore, we could conclude that she had been completely freed from sparganosis. The magnetic resonance imaging (MRI) and ultrasound sonography of her subcutaneous nodule demonstrated the characteristic signs: a band‐like structure in the MRI and a coiled linear hypoechoic body in a clear, oval mass in the ultrasound sonography.
