Monoamniotic twin pregnancy discordant for body stalk anomaly: a case report

Body stalk anomaly, also known as limb-body syndrome, is a rare and lethal congenital anomaly. It presents a major abdominal wall defect and severe kyphosis with either a rudimentary or absent umbilical cord. We present a case of monoamniotic twin discordant for body stalk anomaly diagnosed at 27 weeks. Ultrasound findings demonstrated a normal Twin A, but Twin B was abnormal with a large ventral wall defect and severe kyphoscoliosis. The pregnancy was managed conservatively and concluded with an emergency caesarean section at 31 weeks on account of preterm labour. The unaffected twin survived with no significant morbidity. This case highlights some of the challenges posed to the obstetrician in managing such a rare anomaly in twin pregnancy

Massive subchorionic thrombohematoma: a case report demonstrating serial sonographic changes

Massive subchorionic thrombohematoma (MST) is the presence of a large hematoma or thrombus confined to the subchorionic space. Sonographic findings vary and include placenta descriptions such as heterogeneous, homogeneous, hypoechogenic, or jelly-like mass, which can be differentiated from the normal placenta. Our case report highlights the serial sonographic features observed in a singleton pregnancy from 13 to 29 weeks of gestation. Ultrasound findings of the placenta changed from a 65 ml subchorionic hematoma at 16 weeks to a well-defined placental mass with cystic areas at 20 weeks to an amorphous gelatinous mass at 23 weeks which became primarily replaced by an anechoic lesion with internal septations at 27 weeks. She delivered a live female at 29 weeks. MST usually has a dramatic initial presentation, but these findings may be compatible with a favourable outcome. Serial ultrasound assessment of the placenta is helpful to define the perinatal prognosis and may demonstrate gradual changes and eventual resolution
