case_images: FIG1
case_images: A plain baby-gram X-Ray (Figure 1) demonstrated a midline abdominal mass with multiple ectopic calcified structures indicating bones.
case_images: Abdominopelvic USG of the newborn demonstrating a well-defined cystic structure seen in the center of the abdomen to the left side measuring about 80 x 50 millimeters with heterogeneous soft tissues content which is highly suggestive of a nonviable fetus (blue arrow) seen inside the cyst (yellow arrow). Empty skull with vertebral organization and limb buds formation were also visualized.. USG: ultrasonography

case_images: FIG2
case_images: Abdominal USG (Figure 2) revealed a well-defined cystic structure in the center of the abdomen to the left side measuring around 80 x 50 millimeters with heterogenous soft tissue content, which is highly suggestive of a non-viable fetus inside a cyst, with an empty skull, vertebrae, and limbs.
case_images: MRI of the patient showing a well-defined cystic mass in the left abdominal region anterior to the left kidney (A and B, yellow arrow) with a centrally located fetiform structure (B, blue arrow). The mass compresses and displaces the bowel loops anteriorly and to the right side (B, green arrow).. MRI: magnetic resonance imaging

case_images: FIG3
case_images: MRI showed a well-defined cystic mass in the left abdomen anterior to the left kidney with a centrally located fetus (Figure 3 A and B). Multiple long-shaped hyperintensities that correspond to fetal limbs were also observed. The mass compresses and displaces the bowel loop anteriorly and to the right side (Figure 3 B).

case_images: Exploratory laparotomy with excision of the mass revealing a large encysted mass (A). Excision of the cyst showed a fetus-like structure (B and C) with protruding limb buds and anencephalic features.

case_images: FIG4
case_images: Exploratory laparotomy was scheduled at the age of six days with a left upper abdominal incision, revealing a large encysted mass (Figure 4 A). Dissection of the cyst revealed fetus-like structures (Figure 4 B and C) with limb buds visible and anencephalic features.
