case_images: Abdominal ultrasound revealed a slightly hyperechoic mass measuring approximately 4.30 x 3.08 x 3.30 cm in the lower right abdomen, with an elongated bone fragment measuring around 2.48 cm (Figure 1A). Additionally, an irregular strong spinal echo, measuring approximately 1.91 x 1.02 cm, raised suspicions of fetal intra-abdominal calcifications (Figure 1B). The left scrotum appeared empty (Figure 1C).
case_images: The left wall of the tumor is connected with the left spermatic cord and vas deferens, and the spermatic cord and vas deferens are twisted. (White pentagram).

case_images: The postoperative histopathological findings revealed a 4.5 x 3.5 x 3.5 cm gray-brown specimen resembling intact testicular tissue with sections of spermatic cord tissue measuring about 2.5 cm (Figure 3A). Furthermore, the presence of the spinal structure was also confirmed (Figure 3B). Microscopic examination with HE staining displayed irregular bone and cartilage proliferation (Figure 3C).
