ABSTRACT

OBJECTIVES: To determine the advantages of radiological imaging of a collection of full-term teratological fetuses in order to increase their scientific and educational value. BACKGROUND : Anatomical museums around the world exhibit full-term teratological fetuses. Unfortunately, these museums are regularly considered as "morbid cabinets". Detailed dysmorphological information concerning the exhibited specimens is often lacking. Moreover, fetuses with severe and complex congenital anomalies are frequently diagnosed incompletely, incorrectly or not at all. METHODS: In order to verify diagnoses and to enrich their educational and scientific value, we imaged 41 out of the 72 teratological specimens present in the collection of our Anatomy and Pathology Museum in Nijmegen (The Netherlands) by means of magnetic resonance imaging (MRI) and computed tomography (CT). Additionally, contemporary dysmorphological insights and 3D models are implemented in the teratology education of medical students and residents. CONCLUSIONS: Full-term teratological fetuses have become increasingly rare and deserve a prominent place in every anatomical museum; they are suitable for contemporary teratological research and education. Modern radiological techniques markedly enhance their scientific and didactic value. TEACHING POINTS: • To explore the scientific and educational potential of institutionalised teratological collections • To understand the additional value of radiological imaging in diagnosing teratological specimens • To learn about the specific settings of MRI parameters when scanning fixed specimens • To recognise specific internal dysmorphology in several congenital anomalies.

ABSTRACT

Tuberous sclerosis complex (TSC) is an inherited neurocutaneous disorder. Diagnosis of early onset TSC in newborn infants is usually made by cardiac ultrasound because of circulatory problems due to cardiac rhabdomyoma. Early appearance of cortical tubers on cerebral ultrasound in newborn infants is very rare. Mostly TSC is diagnosed on MRI and not by cerebral ultrasound. Subependymal nodules are the usual presenting sign of TSC on cerebral ultrasound in neonates, which are often misdiagnosed as subependymal hemorrhage, calcifications or ischemic lesions after intrauterine germinal matrix hemorrhage. In this case report, multiple cortical and subcortical tubers are demonstrated in an extremely preterm infant, which were not observed on antenatal ultrasound. Together with cardial rhabdomyoma and the identification of the TSC2 pathogenic mutation in DNA from normal tissue the diagnosis of TSC has been confirmed. To our knowledge this is the first case report of early appearance of disseminated cortical tubers on cerebral ultrasound postnatal in an extremely preterm infant with TSC.
