A cluster of abnormal signal lesions is seen in the left pelvic area, with a maximum cross-section of approximately 5.0 × 4.2 cm. The boundary is still clear, and the signal is uneven. It is iso-hypointense on T1WI and slightly hyperintense on T2WI. (A) DWI is hyperintense (A). Enhancement is uneven, and the boundary between the lesion and the left adnexa is unclear. (B). The red arrow indicates the location of the tumor
