[Vulvar mass in neonatal period : spot the difference].

We report the cases of two female newborns who present, at the first day, a interlabial mass. In both cases, the antenatal scans were normal, and the clinical examination in the delivery room didn't reveal any other abnormality. Similar features may suggest the same diagnosis.

National audit on the appropriateness of CT and MRI examinations in Luxembourg.

Objectives: In Luxembourg, the frequency of CT and MRI examinations per inhabitant is among the highest in Europe. A national audit was conducted to evaluate the appropriateness of CT and MRI examinations according to the national referral guidelines for medical imaging.

Methods: Three hundred and eighty-eight CT and 330 MRI requests corresponding to already performed examinations were provided by all radiology departments in Luxembourg.

Dysmorphic Short Stature: Radiological Diagnosis of Trichorhinophalangeal Syndrome.

Trichorhinophalangeal syndrome (TRPS), a type of skeletal dysplasia, is characterized by a triad of dysmorphic (bulbous nose and large ears); ectodermal (thin and sparse hair); and skeletal (short stature and cone-shaped epiphyses) findings, and this combination is helpful for early diagnosis and appropriate follow-up. A 14-year-old boy presented with short stature and distinctive facial features, and following the first clinical and biological evaluation, no precise diagnosis was reached. Progressive bilateral development of noninflammatory and painless deformity of his second finger required a radiological exam that highlighted the key elements (cone-shaped epiphyses) for final diagnosis.

[Bone disorders and complications of pediatric acute lymphoblastic leukemia : monocentric study and review of the literature].

Bone pain associated with bone marrow infiltration is often present at diagnosis of pediatric acute lymphoblastic leukemia (ALL). It sometimes signs the presence of pathological fracture, lytic lesions, arthritis, or osteitis associated to ALL that can delay the diagnosis. During treatment, bone complications (pain, osteopenia, fracture, avascular necrosis, .

[Rectal prolapse revealing a tumor: The role of abdominal ultrasound].

Rectal prolapse is rare in children and usually benign. However, there are various diseases that can be associated with it, such as cystic fibrosis or other causes of increased abdominal pressure. Here, we review the various underlying conditions that pediatricians or pediatric gastroenterologists should consider in the case of rectal prolapse.

Osteopetrosis mimicking juvenile myelomonocytic leukemia.

A 5-month-old boy developed splenomegaly, anemia, thrombocytopenia with elevated white cells, monocytosis and immature granulocytes in the peripheral blood. Bone marrow showed dysplasia without blastosis. Increased colony-forming unit-granulocyte-macrophage was found in the peripheral blood, mimicking granulocyte-macrophage colony-stimulating factor hypersensitivity.

[Atypical clinical presentation of a neuroblastoma in an infant].

A babygirl, aged six weeks, was hospitalized for rectal prolapse and isolated constipation. The investigation revealed a neuroblastoma (NB) inducing a medullar compression responsible for the sphincter disorders. NB is second among pediatric solid tumors, but is the most frequent cancer among infants.

Paravertebral Burkitt's Lymphoma in a Child: An Unusual Presentation.

Paravertebral malignant tumors constitute 4.8% of cancer cases in pediatric oncology and are mostly composed of neuroblastoma (46.4%) and soft tissue sarcomas (35.

[Nodular focal hyperplasia in a child].

We report the case of seven year old girl, suffering from Steinert's disease and developing a nodular focal hyperplasia. The latter was fortuitously discovered on the occasion of an echography performed during the follow up of a post-catheterisation umbiblical vein hematoma. The lesion increased and became symptomatic.

Neonatal liver cirrhosis without iron overload caused by gestational alloimmune liver disease.

Gestational alloimmune liver disease has emerged as the major cause of antenatal liver injury and failure. It usually manifests as neonatal liver failure with hepatic and extrahepatic iron overload, a clinical presentation called neonatal hemochromatosis. We report on a newborn in whom fetal hepatomegaly was detected during pregnancy and who presented at birth with liver cirrhosis and mild liver dysfunction.

Diastematomyelia: pre- and postnatal multimodal diagnostic approach.

Diastematomyelia is a relatively rare congenital abnormality presenting as a sagittal separation of the spinal cord. Although cases of diastematomyelia have been previously reported, fully documented approaches by both prenatal and postnatal diagnostic workup are rare in the literature. We present a fully studied case of diastematomyelia type I investigated by prenatal US and MRI and postnatal US, MRI and radiography.

Sternal cleft: prenatal multimodality imaging.

Sternal clefts have been reported sporadically, but there are no reports describing complete investigations of the malformation. We describe a child with isolated inferior sternal cleft diagnosed at 33 weeks of gestation and thoroughly investigated by prenatal US, MRI and CT and preoperative US. Our report highlights the importance of accurate and in-depth investigation by multimodality imaging that allows detection of accompanying serious anomalies and, hence, forms the basis for informed parental counselling and for postnatal interdisciplinary care.

Intracranial germ cell tumor.

Germ cell tumours represent about 3 to 8% of pediatric brain tumours. Occurrence of diabetes insipidus is common in the case of suprasellar germ cell tumors. The diagnosis may be advanced by MRI owing to the location and relatively univocal characteristics of the lesion signal.

Temple-Baraitser syndrome: a rare and possibly unrecognized condition.

Temple-Baraitser syndrome, previously described in two unrelated patients, is the association of severe mental retardation and abnormal thumbs and great toes. We report two additional unrelated patients with Temple-Baraitser syndrome, review clinical and radiological features of previously reported cases and discuss mode of inheritance. Patients share a consistent pattern of anomalies: hypo or aplasia of the thumb and great toe nails and broadening and/or elongation of the thumbs and halluces, which have a tubular aspect.

[Management of medulloblastoma in children: the experience of a single institution in Liege from 1991 to 2005].

We present the experience of the Citadelle Hospital (Liege, B) in the diagnosis, treatment and follow-up of medulloblastoma in children. A retrospective study of 10 cases of medulloblastoma was performed. Five years after diagnosis, the event-free survival was 77%.

Nodular fasciitis: correlation of MRI findings and histopathology.

Objective: To compare the histopathology of nodular fasciitis (NF) with the magnetic resonance imaging (MRI) findings in order to evaluate the basis of the MR signal characteristics.

Design And Patients: Ten patients with NF, nine females and 1 male, with an age ranging from 13 to 58 years (mean 26.8 years) were studied.

Acute abdomen. Is ultrasonography useful, essential or unnecessary?

Abdominal ultrasonography in acute conditions gives sometimes the definite diagnosis or at least indicates a strategy for further examinations. This technique is constantly accurate for the upper part of the abdomen, and its classical indications are dominated by cholecystitis, biliary and urinary lithiasis, pancreatic and aortic painful circumstances. However, its role has been emphasized recently, after famous publications about the usefulness of high resolution ultrasonography for appendicitis and various gut-related acute conditions.
