[Spinal localization of a solid aneurysmal cyst. Clinical, radiologic and histopathological aspects].

An 8 year old child with a "solid" aneurysmal cyst of L4 posterior arch was investigated by straight films, bone scintigraphy and CT scans. The suggested diagnosis had been a benign tumor, probably an osteoblastoma. Initial histopathology results were in favor or a non ossifying fibroma or a chondromyxoid fibroma, this lacking concordance with the usual epidemiology of primary spinal tumors in children. A description is given of the histologic characteristics of this new histopathologic entity first described by Sanerkin in 1983.

[Magnetic resonance imaging in spinocerebellar degenerative diseases (apropos of 8 cases)].

The results of NMR imaging in 8 cases of spinocerebellar degenerative diseases (age 4 to 19 years) are presented. In Friedreich ataxia (5 cases), spinal atrophy was constant and often severe, and was associated with a moderate cerebellar and/or bulbar atrophy in 3 cases. In hereditary spastic paraplegia, the only finding was a mild spinal atrophy in 2 of the 3 cases.

[The multicystic kidney. Anatomo-radiological study of 19 operative specimens. Practical and pathogenic consequences].

19 specimen of pathologically proved multicystic kidneys were opacified; first through the ureter and second, if the ureter was not patent, through a puncture of one of the cysts (or several if the first cyst did not communicate with the ureter or with other cysts). The results are as follows. The ureter was hypoplastic but patent in 12 and communicated with some of the cysts in 9 or with all the cysts in 3. These communications consisted of large (12 cases) or small (15 cases) canals, or both large and small canals (11 cases). When patent, the ureter was connected to these canals. Moreover in most of the cases, there was a communication between cysts through such canals. Finally, only 3 cases fitted with the classical description having an atretic ureter and non communicating cysts. Our conclusion is that the same basal defect is present in congenital obstructions of pelvis and calyces; there is a continuous spectrum of malformations between congenital hydronephrosis, hydrocalyces and multicystic kidneys.

Unilateral mid-femoral periosteal newbone of varying aetiology in children. Radiographic analysis of 25 cases.

Thigh pain is a serious condition in childhood and should be promptly and thoroughly investigated. Twenty-five cases of thigh pain lasting between 1 day and 7 months with mid-femoral periosteal thickening were analysed. There were 10 patients with Ewing's sarcoma, 7 with eosinophilic granuloma, 1 with osteoid osteoma, 1 with leukaemia, 3 with osteomyelitis, 1 with myositis and 2 with post-traumatic periosteal reaction. It was shown that patients with Ewing's sarcoma and eosinophilic granuloma have certain patterns of X-ray changes of high diagnostic value, which allow a proper diagnosis in most cases.

[Giant Meckel's diverticulum presenting as tumor].

The authors report a case of giant Meckel's diverticulum, presenting as a subumbilical abdominal mass, associated with an infectious picture and anemia in a 16 month-old boy. Epidemiologic, pathologic and clinical features of this rare disorder are reviewed as are the diagnostic means. The differential diagnosis with other cystic masses of the umbilical area (omphalo-mesenteric duct cyst, urachal cyst, mesenteric cyst, duplication) is discussed.

[Posterior hernia of a calcified disk in children. Apropos of 2 cases].

Posterior herniation of a calcified disk was detected in two children. A 10-year-old boy presented with cervicobrachial neuralgia at the C7 level secondary to herniation of a calcified C6-C7 disk treated by surgery. A 13-year-old boy was seen with a post-traumatic painful stiffness in the thoracic region posteriorly, without neurologic complication, secondary to a herniated calcified T4-T5 disk. Surgery was not performed and the course was favorable with regression of clinical signs and spontaneous disappearance of the herniated calcified fragment. A literature review showed reports of 21 identical lesions, full details being provided in 9 cases. Epidemiologic data, clinical manifestations, diagnostic means and management of these patients are discussed.

Primary vertebral tumours in children. Report of 20 cases with brief literature review.

20 cases of primary benign and malignant bone tumours in children were reported. The most common tumours were Ewing's sarcoma, aneurysmal bone cyst, benign osteoblastoma and osteoid osteoma. Some rare primary bone tumours in children (osteochondroma, chondroblastoma?, primary lymphoma of bone and neurofibromatosis with unusual cervical spinal changes) were also reported. The authors believe that radiographic findings together with clinical history and clinical examination may yield a high percentage of accurate diagnoses. Although microscopy is essential in the final diagnosis, the microscopic report should be viewed with caution.

Multicystic dysplasia in the upper component of the complete duplex kidney.

Four cases of neonatal multicystic dysplasia involving the upper part of a complete duplex kidney are presented. This malformation, suspected on antenatal ultrasound examination, was confirmed by postnatal IVP and ultrasound. This emphasizes the need to perform an IVP when the diagnosis of multicystic kidney is suggested by ultrasound. Conservative surgery may then be achieved, as in three of the four cases.

[Nephroblastoma with egg-shell peripheral calcifications. Apropos of 3 cases].

Three cases of nephroblastoma presented "egg-shell" peripheral calcifications of pseudocystic appearance of radiology. These peripheral lesions are compared with the more commonly reported central calcifications. Their pathology is unknown and they lack prognostic significance of any importance. As for all nephroblastomas the diagnosis is based on straight abdomen images, intravenous urography, ultrasound and computed tomography. Differential diagnosis is basically from renal adenocarcinoma in children, the latter often exhibiting similar calcifications, the distinction between the two types of tumor depending on age of onset. These calcified lesions are non-specific findings and various diagnoses are discussed.

[Echography and computed x-ray tomography in the diagnosis and surveillance of hepatoblastoma. Apropos of 5 cases].

Ultrasound imaging and CT scans were performed in a homogeneous group of five patients with hepatoblastoma. Effectiveness in determining characteristics of the tumor mass and its location and possible vascular extension were compared for the two exploratory methods. Findings suggest that these two examinations are useful and complementary for the diagnosis and follow up of hepatoblastoma.

[Congenital toxoplasmosis and transfontanelle brain echography. Apropos of 8 cases observed in newborn infants and infants].

The undeniable value of brain ultrasound imaging in the detection of ventricular dilatation is emphasized, and a classification of intracranial calcifications proposed: hyperechogenic, nodular and irregular large images and those without a posterior shadow cone. Comparison between simple films and particularly computed tomography images was conducted in the cases studied.

[Superior tibial epiphyseal osteochondroma with intra-articular development. Apropos of 2 cases in children].

Two cases of intra-articular development of an osteochondroma in the proximal epiphysis of the tibia are reported. The first case, a 3 year old boy, resulted in blocking of the knee. After resection of the mass the diagnosis was confirmed by pathology. The second patient, an 8 year old boy, had no symptoms and surgery was not performed, although ablation was required of an associated astragalian osteochondroma of tibiotarsal intra-articular development. Relations between these epiphyseal osteochondromata and hemimelic epiphyseal dysplasia and metachondromatosis are discussed.
