Omphalothoracopagus: A Case Report of Conjoined Twins and the Impact of Pelvimetry.

Pelvimetry, a radiographic imaging technique, is essential in evaluating pelvic dimensions and planning delivery methods, particularly in complex cases such as conjoined twins. This case report details the diagnosis of omphalothoracopagus twins in a 23-year-old G1P0 patient (first pregnancy with no prior deliveries) at 20 weeks of gestation using advanced imaging techniques, including 3D ultrasound, pulsed wave Doppler, and maximum intensity projection. Early prenatal imaging identified shared anatomy, including a single liver and a six-chambered heart, aiding in assessing surgical feasibility. Despite the advanced diagnostic tools, the severe anomalies precluded surgical separation, and the pregnancy was terminated. This case underscores the importance of pelvimetry and advanced imaging in guiding clinical decision-making and improving maternal and fetal outcomes.
