case_images: Magnetic resonance imaging of the lesion: A/Coronal T2 weighted B/Axial
  T1 weighted images showing a large well-defined multiloculated irregular
  cystic lesion of 211 x 199 x 106 mm arising from the right ovary with
  hyperintense septal fat.

case_images: fig1-20363613221148839
case_images: The abdomino-pelvic magnetic resonance imaging (MRI) showed a large multiloculated irregular cystic lesion of 211x199 x 106 mm arising from the right ovary with thickened wall and some endocystic vegetations, seat of irregular and thickened partitions as well as vegetations (Figure 1).
case_images: Macroscopic findings of the specimen. The tumor is arising from the broad
  ligament. The mass is composed of a yellowish lobulated glistening
  gelatinous cut-surface.

case_images: fig2-20363613221148839
case_images: The cross-sections of the tumor showed large number of nodular areas showing a gelatinous cut surface (Figure 2).
case_images: Histological findings of low-grade myxoid liposarcoma. H&E, original
  magnification x40. The tumor is composed of an abundant myxoid matrix,
  lymphangioma-like cystic spaces with component of mature fat tissue.

case_images: fig3-20363613221148839
case_images: Tumor cells had indistinct cytoplasmic borders and oval, stellate-shaped nuclei (Figure 3).
case_images: Immunohistochemical staining of low-grade myxoid liposarcoma. Diffuse
  nuclear and cytoplasmic expression of S100 protein in tumor cells.

case_images: fig4-20363613221148839
case_images: On immunohistochemical staining, tumor cells were positive for S-100 (Figure 4), and negative for CK, CK7, EMA, and HMB45.
