Choriocarcinoma with lumbar muscle metastases: A case report

Figure 1 Ultrasonographic image of the lesion. The uterine cavity and cervical canal were empty. Ultrasonography revealed that the mass was heterogeneous with a mixture of cystic and solid echogenicity. A: The left adnexa mass on the day of hospital admission; B: The left adnexa mass six days after admission.

Figure 2 Patient serum β-human chorionic gonadotropin levels. A: Increasing levels of serum β-human chorionic gonadotropin (β-hCG) levels before surgery; B: β-hCG dropped to normal levels after cycle 2 of chemotherapy. β-hCG: β-human chorionic gonadotropin.

Figure 3 Magnetic resonance imaging of the lesion. Low signal intensity on T2-weighted image (T2WI) (A) and high signal intensity on T1-weighted image (T1WI) (B); C: T2WI, coronal plane; D: T1WI, coronal plane. Orange arrows indicate the lesion.
