Figure 1 Preoperative magnetic resonance imaging: contrast-enhanced (A) axial, (B) coronal, and (C) sagittal T1WI images of a 33 × 22 cm multiseptated cystic mass with some enhanced solid portion and a normal uterus morphology (arrow).

Figure 2 (A) Transverse, (B) sagittal, and (C) coronal (18F)-2-deoxyglucose positron emission tomography images, demonstrating that the abdominopelvic mass had multiple septated cavitary lesions with mildly increased wall metabolism (maximum standardized uptake value 2.3).

Figure 3 (A) Gross photograph of the resected tumor, demonstrating smooth glistening external surface with coarsely trabeculated huge internal solid portion. Histopathologic examination revealed (B) cellular myoma with hyaline infarction and central abscess formation and (C) a cellular neoplasm composed of oval to spindle cells with very low mitotic figure (1/50 high-power fields) (hematoxylin and eosin, ×100). Tumor cells were positive for muscle-specific actin but negative for CD34, CD117(c-kit), and S-100 on immunohistochemistry.
