  ). To better characterize the mass, an abdominal magnetic resonance imaging was performed and the initial diagnosis was confirmed (

case_images: The child complained of recurrent abdominal pain and dysuria for 1 month; an abdominal ultrasound and magnetic resonance imaging (MRI) showed a 6 cm right-sided ovarian mass that was suspected to be a teratoma ( Fig. 1A-C ). However, no ovarian mass was found, but an 8-cm exophytic lesion was discovered, arising from the retroperitoneum, on the right side of the pelvis, adjacent to the bladder with multiple adhesions with the ascending colon and the uterus ( Fig. 1D ).
case_images: Lipoblastoma histology: multilobulated soft tissue lesion comprising groups of peripherally lipoblast that are separated by fibrous septa and a distinct peripheral pseudocapsule was typical of all cases. Hemosiderin staining and chronic inflammation with extensive liponecrosis were present in patient 1(
  A
  ,
  B
  ) and signs of vascular congestion were present in patient 2 (
  C
  ,
  D
  ). Hemosiderin staining and chronic inflammation were particularly represented in patient 3 (

case_images:  On abdominal ultrasound, an ileocecal intussusception was confirmed ( Fig. 3A, B ). Water-soluble contrast enema was performed but was ineffective ( Fig. 3C ); hence, the patient underwent surgical exploration via transverse right-sided supraumbilical laparotomy ( Fig. 3D ).

case_images: MRI showed a multilobulated epifascial lesion measuring 8 x 6 cm, in the context of the gluteal muscle extending to the pelvis ( Fig. 4A-C ). Intraoperatively, an encapsulated multilobulated subcutaneous fatty tumor was discovered ( Fig. 4D ).
