Mitral stenosis was diagnosed noninvasively by echocardiography and Doppler imaging in 2 Bull Terriers. Two-dimensional echocardiography revealed severe atrial and moderate left
ventricular dilatation
; severely reduced mitral valve opening excursion; doming of the cranial mitral valve leaflet into the left ventricle during diastole; thickened, nodular cranial mitral valve leaflets; and reduced mitral valve orifice. M-mode echocardiographic findings additionally indicated greatly diminished mitral valve E to F slope and abnormal caudal mitral valve leaflet motion. Color flow Doppler imaging revealed bright bursts of color with aliasing originating from the stenotic mitral valve orifice, extending into the left atrium during systole, and into the left atrium during diastole. Spectral Doppler recordings revealed transvalvular mitral valve gradients and prolonged pressure half-times. Necropsy performed on 1 dog revealed extremely thickened, nodular, and stiff mitral valves with short, thickened, and
fused
chordae tendineae. The diagnosis of mitral valve stenosis was easily facilitated with diagnostic ultrasonography.

Schizencephaly is a neuronal migration anomaly characterized by gray matter lined clefts extending from the ventricle to the cortical surface leading to specific lesions, well demonstrated by imaging. The lips of the clefts can be
fused
or separated. Prognosis is related to the extend of the involved cortex. Both genetic and acquired factors can be responsible for this pathology. Three cases of antenatal diagnosed open schizencephaly are reported. Two cases are unilateral and one is bilateral. A cerebral anomaly has been detected in all cases by routine ultrasonography (US) revealing a
ventricular dilatation
with cortical associated abnormalities. Prenatal magnetic resonance imaging (MRI) permitted the diagnosis in the 3 cases. All cases had led to abortion because of the importance of the cortical defect. The aim of this report is to point out the importance of fetal MRI in the diagnosis of migration disorder and to discuss the medical implications. Indeed, MRI is better suited than US for the prenatal diagnosis of schizencephaly, being able to detect normal and abnormal brain cellular migration, especially with fast imaging (HASTE sequences). With its multiplanar imaging capability, MRI demonstrates the cleft extending from the pial surface to the ventricular ependyma and thus provides characteristic diagnosis of this disorder. Moreover,
ventricular dilatation
, a frequent anomaly detected by US should be completed with MRI in order to research a neuronal migration disorder.

We report on a newborn infant with characteristics of Laurin-Sandrow syndrome (LSS). She had hypertelorism, flat nose with grooved collumella, "V" shaped mouth with thin lips, 7 well-recognized and
fused
digits and 1 additional postaxial bilateral appendix on each hand. The right and left feet had 12 and 11 toes, respectively, the 4 external ones were recognizable, and the rest were
fused
in a uniform mass but with independent nails. There was also a 2.3 cm-long digitiform appendix in the internal part of both feet. Radiographs showed seven metacarpals and seven metatarsals with similar morphology; both hands lacking thumbs. The four lateral-most toes had regular shaped phalanges and the rest were irregular. The left digitiform appendix had three bones and the right only two. Tibiae were shorter than fibulae. Central Nervous System examination showed an abnormally shaped olivary nucleus, cerebellar cortical heterotopias, gray matter ectopias in both spinal cord and hemispheric white matter, marked
ventricular dilatation
, and moderate diffuse white matter gliosis. Karyotype was 46XX. A complete necropsy study is presented and all reported cases are reviewed focusing on their phenotypic differences and their nosologic classification. We propose the entity LSS only in cases with symmetric tetrameric polysyndactyly, especially cup-shaped hands and mirror feet, in association with nasal anomalies.
