This retrospective study compared the prenatal ultrasound (US) diagnosis with autopsy findings in 61 intact fetuses following induced abortion and 36 fragmented fetuses from dilatation and evacuation (D&E). In intact fetuses, complete agreement between US diagnosis and autopsy findings was achieved in 65.6% of cases in the central nervous system (CNS) and 47.5% in other somatic organ systems (SOS). There were major differences between US and autopsy findings involving the CNS in 6.5% of cases and SOS in 27.9%. Correlation was better for evaluation of renal anomalies (complete agreement in 63.6% of 11 suspected cases, 2 false-positive and no false-negative cases) than congenital heart disease (complete agreement in 27.3% of 11 suspected cases, 5 false-positive and 3 false-negative cases). In D&E specimens, a prenatal diagnosis of neural tube defect (NTD) was confirmed in 90% of cases. However, due to fragmentation of fetal parts, the US diagnosis in the CNS could not be confirmed totally (69.4%) or partially (2.8%) in fetuses with chromosomal abnormalities (ChA) or multiple congenital anomalies (MCA). Nonetheless, the US diagnosis of SOS was confirmed in six cases on D&E, including Meckel-Gruber syndrome, cystic hygroma, renal agenesis with contralateral renal dysplasia, cardiac defect, fetal hydrops, and tracheal atresia. Our results show that a thorough autopsy of an intact fetus after abortion is necessary to confirm prenatal diagnosis and allow proper management and counseling. The pathologic examination of D&E specimens can reliably confirm the US diagnosis of NTD, but it is very limited in identifying other fetal anomalies.
Lethal skeletal dysplasias (LSD) are a heterogeneous group of rare but important genetic disorders characterized by abnormal growth and development of bone and cartilage. We describe the diagnosis and outcome of 29 cases of lethal skeletal dysplasias evaluated between January 1989 and December 1996 at the University of Maryland Medical Center and the Ultrasound Institute of Baltimore. Two cases presented at delivery with no prenatal care while the remaining 27 cases were identified by antenatal sonography. Final diagnoses included thanatophoric dysplasia (14), osteogenesis imperfecta, type II (6), achondrogenesis (2), short rib syndromes (3), campomelic syndrome (2), atelosteogenesis (1), and no evidence of a skeletal dysplasia (1). Twenty out of 27 pregnancies were terminated with an average at detection of 21.6 weeks. The other 7 pregnancies that went on to deliver had an average age at detection of 29.2 weeks. Fetal abnormalities in the terminated pregnancies were identified at a significantly earlier gestational age (P = 0.0016) than the pregnancies that continued. While the identification of LSD by sonography was excellent (26/27), only 13/27 (48%) were given an accurate specific antenatal diagnosis. In 8/14 (57%) cases with an inaccurate or nonspecific diagnosis there was a significant or crucial change in the genetic counseling. Thus, while antenatal sonography is an excellent method for discovering LSD, clinical examination, radiographs, and autopsy are mandatory for making a specific diagnosis.

A diverticulum of the hepatic duct was found in a 25-year-old woman. Cholangiography revealed that the diverticulum was cystic in nature and contained several stones. Since the intrahepatic ducts are never seen at surgery, the authors stress the importance of preoperative and operative cholangiography in locating such anomalies.
The authors report a case of classic esophagitis simulating candidiasis radiographically. Endoscopy provided pathological conformation of herpes infection, showing typical multinucleated cells with intranuclear inclusion bodies.
