  < Go Back to Previous Page


The Cases of the month (CoM) have been introduced by Christoph F. Dietrich as first Editor from 2008 to 2009 followed by Paul S. Sidhu from 2010 to 2015, with Maija Radzina taking over in 2016. The earliest case of the month went online in March 2008. The Publication Committee envisaged regular contributions to include artefact of the month, tip of the month in addition to cases that would be of interest. Topics have ranged from Focal liver lesions (FLL), Crohn's disease, Echoscopy, to a rare double gallbladder. All these cases are listed on the EFSUMB website under Case Archive

The translations into fourteen foreign languages can all be accessed from this page with all cases now translated into Chinese.

The Case of the Month continues to be the most viewed item on the EFSUMB website, with as many as 161,471 hits in the last four months of which 94% viewed the English version and other viewing the Latvian, Russian, Chinese and Italian translations.

If you would like to translate any of the cases please contact Maija Radzina or if you wish to submit a Case of the Month resource to EFSUMB for consideration email:

Case of the Month - APRIL
A case of prenatally diagnosed Binder syndrome

2nd Department of Obstetrics and Gynecology, Aristotle University of Thessaloniki, Thessaloniki, Greece

Binder syndrome (OMIM 155050, ORPHA 1248) is a rare condition characterized by midfacial hypoplasia, short nose and flat nasal bridge, underdeveloped upper jaw and a relatively protruding lower jaw (underbite) (http://www.orpha.net). Its inheritance pattern is unclear, but some recurrent cases may be explained by autosomal recessive inheritance with reduced penetrance or by multifactorial inheritance (1). Binder syndrome shares some common features with chondrodysplasia punctata (OMIM 215100) and it has been suggested that it may actually represent a mild form of the latter condition (2). Vitamin K deficiency has also been postulated as an environmental mechanism, resulting from maternal warfarin or phenytoin therapy, alcohol consumption, excessive vomiting, digestive bypass or an autoimmune disease (3-5). The exact prevalence of the condition is not known, but it may be in the realm of 1:10,000 (http://www.orpha.net).
Prenatal detection of the Binder phenotype has been reported at the time of the second-trimester since 2000 (6), and it was based on the recognition of a characteristic facies with flattened nose in the midsagittal plane verticalized nasal bones and underbite (class III malocclusion).

Case report

A 43-year old woman with 1 previous healthy child and a low-risk first-trimester screening test in the index pregnancy, presented at 21+4 weeks for routine second-trimester scan. At examination, a present (length 5.8 mm) but verticalized nasal bone was observed, resulting in a flat facial profile with underbite (Figures 1 and 2). No other major defects were detected and fetal biometry was observed. The couple were counselled about the tentative diagnosis of Binder syndrome, its potential implications and the limitations of prenatal diagnosis. Amniocentesis with array comparative hybridization (aCGH) was performed, indicating a normal female karyotype. At follow-up scans, no additional abnormalities were detected and the biometry of the long bones remained within normal limits. The course of pregnancy was uneventful, and an infant of 2750 g was born at 38+2 gestational weeks by elective caesarean section due to previous cesarean. At two months of life, the infant was doing well, and the only complaint at the time was tedious breathing and episodes of postprandial cough.

There are only few published cases with prenatal diagnosis of Binder syndrome (3, 6). The difficulties faced by examiners and parents after the identification of a Binder phenotype at the fetal anomaly scan mostly focus on three issues, i.e. ascertainment of the diagnosis, obstetric management and prognosis.

Ascertainment of diagnosis

Although the Binder profile is distinct, the lack of a recognized underlying chromosomal or molecular abnormality makes its prenatal ascertainment impossible. In a recent report of 8 cases with a prenatal Binder phenotype, one had fetal warfarin syndrome, one infantile sialic acid storage, one possible Keutel syndrome, and the other five had unclassifiable types of chondrodysplasia punctata (3). Although some of these conditions may have some additional sonographic features that can facilitate differential diagnosis (e.g. rhizomelic shortening of the long bones for autosomal recessive chondrodyspasia punctata), this is not always the case. It is therefore wise that detection of a Binder phenotype should trigger fetal karyotyping, fetal neurosonography or MRI (to exclude holoprosencephaly) and a helicoidal scan to detect stippling associated with chondrodysplasia punctata (3). Even so, the parents should be counseled that Binder syndrome is a tentative diagnosis prenatally, and that not all genetic syndromes can be prenatally excluded. Faced with this uncertainty, many parents would opt for pregnancy termination; among a total of 16 published cases with prenatal diagnosis, 6 (38%) chose for a termination (3, 6-10).


Hearing loss has been reported in 5% of Binder syndrome cases. The syndrome’s unique facial defects can be surgically corrected using a multi-stage multi-disciplinary approach which has a better prognosis if started early in life. Postponing surgical treatment results in a missed opportunity of normal-like facial growth and prolongation of the psychological burden, imposed by a negative self-image (11). Mental retardation, although reported in limited cases, it is not considered a significant feature of the syndrome (6).
It is important that antenatally diagnosed Binder Phenotype cannot definitely exclude more serious conditions, potentially involving neurodevelopmental delay. As noted before, out of eight cases of Binder phenotype antenatally diagnosed by Levaillant et al, two (25%) had an isolated Binder phenotype, while the remaining cases were related conditions sharing a similar phenotype.

Obstetric and perinatal care

No specific modification of the obstetric care is required. Recently, Blumenfeld et al reported three cases of antenatally diagnosed Binder phenotype associated to chondrodysplasia punctata, complicated by respiratory distress during the immediate post-natal period, attributed to obstruction of the narrowed upper airway (7). Therefore, care should be taken for preparation for neonatal resuscitation in such cases.
