OBJECTIVE: We present prenatal diagnosis of familial 3p26.3p25.3 deletion in a pregnancy associated with a favorable fetal outcome and asymptomatic carrier parent and family members in three generations. CASE REPORT: A 35-year-old, gravida 2, para 1, woman underwent amniocentesis at 17 weeks of gestation because of advanced maternal age and the carrier of distal 3p deletion. She was phenotypically normal, and there was no family history of congenital anomalies. Amniocentesis revealed a karyotype of 46,XY,del(3)(p26...

OBJECTIVE: Chronic ectopic pregnancy is a variant of ectopic pregnancy featured with a low or normal serum beta-human chorionic gonadotropin (β-hCG) test. Obscure clinical presentations and non-specific images make chronic ectopic pregnancy a diagnostic dilemma until now. CASE REPORT: A 40-year-old female was misdiagnosed as tubo-ovarian abscess initially due to chronic lower abdominal pain, negative pregnancy test, and a complicated pelvic mass on abdominal CT scan and serial follow-up ultrasonography...

OBJECTIVE: Cerebral arteriovenous malformation during pregnancy is rare but lethal disease that usually present with new-onset seizures and headaches mimicking eclampsia. We report a rare case of cerebral arteriovenous malformation with abrupt seizures in the third trimester. CASE REPORT: A 28-year-old primipara was brought to our emergency department at 32 6/7 weeks of gestation with new-onset acute seizures and hypertension. Owing to neurological deterioration, the patient underwent emergency cesarean delivery...

OBJECTIVE: We present low-level mosaic trisomy at amniocentesis in a pregnancy associated with cytogenetic discrepancy between cultured amniocytes and uncultured amniocytes, perinatal progressive decrease of the trisomy 7 cell line and a favorable fetal outcome. CASE REPORT: A 40-year-old, primigravid woman underwent amniocentesis at 16 weeks of gestation because of advanced maternal age. Amniocentesis revealed a karyotype of 46,XY in cultured amniocytes. Simultaneous array comparative genomic hybridization (aCGH) analysis on the DNA extracted from uncultured amniocytes revealed the result of arr (7) × 2-3, (X,Y) × 1, consistent with 24% mosaicism for trisomy 7...

OBJECTIVE: We present prenatal diagnosis of de novo 10p12.1p11.23 microdeletion encompassing the WAC gene in a fetus associated with bilateral hydronephrosis on prenatal ultrasound. CASE REPORT: A 40-year-old, gravida 2, para 1, woman underwent amniocentesis at 17 weeks of gestation because of advanced maternal age. Amniocentesis revealed a karyotype of 46,XY. Level II ultrasound at 22 weeks of gestation revealed bilateral hydronephrosis and right clubfoot. At 23 weeks of gestation, repeat amniocentesis revealed the result of arr [GRCh37] 10p12...

OBJECTIVE: We present mosaic distal 9p deletion at prenatal diagnosis in a pregnancy associated with a favorable fetal outcome. CASE REPORT: A 34-year-old, primigravid woman underwent amniocentesis at 17 weeks of gestation because of advanced maternal age. Amniocentesis revealed a karyotype of 46,XY, del(9)(p23)[8]/46,XY[17]. Simultaneous array comparative genomic hybridization (aCGH) analysis on the DNA extracted from uncultured amniocytes showed 43% mosaicism for the 9p24...
