August 19, 2016 showed moderately and poorly differentiated SCC (Figure 1). A total-body computed-tomography scan and whole-body bone imaging, performed to determine disease stage, were negative for distant metastases.
Mass of 37x35 mm detected in the left inguinal region on pelvic MRI. (A) Low signal intensity of approximately 37x35 mm detected in the left inguinal region on T1-weighted imaging (arrow). (B) High signal intensity of approximately 37x35 mm detected in the left inguinal region on T2-weighted imaging (arrow).

On November 18, 2018, the left inguinal mass was approximately 33x33 mm on MRI (Figure 3).
Mass of 21x16 mm and a nodular shadow of approximately 9x8 mm detected in the left inguinal region on pelvic MRI. (A) Low signal intensity of approximately 21x16 mm detected in the left inguinal region on T1-weighted imaging (arrow). (B) High signal intensity of approximately 21x16 mm was detected in the left inguinal region on T2-weighted imaging (arrow). (C) Mild enhancement of a nodular shadow (9x8 mm) after injection of contrast-enhancing agent (circle).

A 21x16 mm mass and a nodular shadow of approximately 9x8 mm were detected in the left inguinal region on pelvic MRI (Figure 4), indicating that the mass in the groin was receding and the particle implantation was effective.
