Background:

Twin reversed arterial perfusion (TRAP) sequence is a rare complication of monochorionic twin pregnancies.
It involves reversed blood flow from a structurally normal 'pump' twin to a malformed, non-viable co-twin.

Observation:

A case report details a primigravida diagnosed at 31 weeks gestation.
Ultrasound and MRI confirmed a monochorionic pregnancy with a viable twin and an acardius acephalus twin.
The pump twin was monitored weekly using ultrasonography, echocardiography, and Doppler studies.

Findings:

The patient delivered a healthy baby and an acardius acephalus fetus at term.
Plain X-ray confirmed the absence of cephalic structures in the acardius fetus.

Implications:

Perinatal mortality for the pump twin ranges from 35% to 55%.
Early diagnosis using advanced imaging techniques is essential for timely intervention.
Improved diagnostic strategies can enhance the prognosis for the pump twin in TRAP sequence.
