The diagnosis is sometimes not easy, it can be done by means of radiography, ultrasonography, tomography and magnetic resonance which is gaining prominence due to its high resolution, low irradiation and the non-use of a contrast medium [7, 9, 10], in some cases they can be underdiagnosed, being reported as teratoma, which is one of the differential diagnoses and whose differentiation is given by the presence of a vertebral organization with buds of the limbs and other organ systems [7], being of great relevance due to the malignant potential of the latter, this being refuted as a point of differentiation by some theories until now without solid foundations. Abdominal ultrasound is performed that reports spaceoccupying mass with probable cystic appearance at the level of the left kidney, a scintigraphy is performed that shows kidneys in a normal position, left kidney increased in size, with a welldefined area of hypouptation that involves a large part of the kidney in the upper and middle regions of it, with minimal uptake area in the lower pole. The two vessels and the left kidney are preserved, mass is extracted finding in its interior cetrino liquid as seen in image 2, in addition the presence of a fetus with upper and lower extremities and two more joined fetuses is evidenced forming a mass effect where only limbs are distinguished, they are extracted and the sample is sent to pathological anatomy study with report of fetus in fetu. In all cases, the fetus was anencephalic and the lower limbs were more developed than the upper limbs.
