[Right inguino-pelvic cystic lymphangioma].

We report an unusual case of a pelvic cystic lymphangioma. The first symptom was an inguinal mass which evoked a lymph node. Diagnosis was suspected thanks to CT. Surgery confirmed the diagnosis. It is an unusual aspect of a malformation which is itself not frequent.

About one case of vertebral chondroblastoma.

The authors report the case of a 9-year-old child which suffered from a chondroblastoma of the cervical spine. He had clinical signs of superior mediastinum compression with inflammation of the respiratory upper air-way. Surgery was performed. Diagnosis was established by the pathologist. The recurrence one year later was treated again by surgery and also by radiotherapy. Another recurrence four years later was fatal. The difficulties of the diagnosis and the appearance of recurrences in some cases of chondroblastoma are reviewed in the literature.

[Rare localizations of digestive adenocarcinoma in children. Apropos of 2 cases].

The authors report two cases of adenocarcinoma of the digestive system in children both of which were located in unusual sites. A child of 9 years old had an adenocarcinoma of the small bowel and a boy of 16 years who was known to have a long-standing hiatus hernia developed an adenocarcinoma of the oesophagus. In children these tumors have some characteristic features. They develop on a preexisting lesion. Evolution is rapid. From the pathological point of view, anaplasic and colloide patterns are frequent.

[Pleural involvement caused by contiguity or metastases in primary malignant bone tumors in children].

Pleural location of primary osseous malignant tumors of children are infrequent. They may be secondary from a distant primary osteosarcoma. It is necessary to investigate them via conventional chest X-ray followed by a CT of the thorax. This examination shows the pleural lesion, its limits and calcifications. It must be remembered that this examination doesn't always confirm the pleural location of the lesions, the angle that they subtend is not an accurate guide. Comparison with clinical data is essential in difficult cases.

[Lacunae between metaphyses and growth cartilage].

Metaphyseal growth defects of the distal femur are usually bilateral and well delimited. There is no pain. They are different from the cortical defects because they are closer to the metaphyseal line and more central located. They disappear with growth and there is no complication. The images are different from those of the sub-acute osteomyelitis and of metastasis. These metaphyseal growth defects are variants of the normal metaphyseal resorption.

[Arterial hypertension caused by extrinsic compression of the renal artery of tumor origin in a child].

Stenosis of the renal artery secondary to an extrinsic acquired compression of the renal artery because of a tumor is rare. We report two cases. The first case is a boy of 14 months with a large neurogenic tumor from the right renal plexus with compression of the right renal artery. The second case is a girl of 2 years which had a neuroblastoma displacing the right kidney. The right renal vessels were invaded by very calcified solid masses and the removal was very difficult. Arterial hypertension secondary to an acquired unilateral renal stenosis may be healed definitely thanks to surgery.

[X-ray computed tomographic aspects of spinal aneurysmal cysts in children].

The interest of CT imaging in a case of aneurysmal bone cyst of the posterior arch of the 6th cervical vertebra in a 10 y.o. child is underlined. The value of intra tumoral densities which are relatively low, inferior to 100 Hounsfield unit is stressed but the most contributory feature in this case was the presence of a fluid level inside the cyst due to different densities of fluid components into the cyst.

[Hepatic calcification in children. Review apropos of 4 personal cases].

The authors describe the main patterns of the calcifications of the liver and present the different causes which are numerous. Value of the radiological procedures, mainly ultrasound and computer tomography is emphasized. They are necessary for the diagnosis of the type of calcifications and of the disease of the patient.

[Course of diaphyseal dysplasia. Camurati-Engelmann disease followed for 14 years].

The authors report a case of a child with Camurati-Engelmann disease de Camurati-Engelmann followed-up for 14 years. The diagnosis was made at the age of 5 years, with a typical picture. During the course of the disease, certain discordant facts emerged with, in particular, the appearance of osteoporotic lesions in the pelvis, metaphyses, epiphyses and skull. This led to the possibility of other diagnoses being envisaged but none could be made definitely. Furthermore, the osteoporotic lesions could not be explained by corticosteroid therapy which was taken in too irregular a manner. Is there a borderline disease within the broad definition of diaphyseal dysplasia?

[Peritoneal metastasis of a pineoblastoma in a patient with a ventriculo-peritoneal shunt].

A 12 years old child had an increase of intra cranial pressure secondary to a large pinealoblastoma. A ventriculo peritoneal shunt procedure was performed followed several days later by a partial resection of the pinealoblastoma. One year later, ultrasound and computed tomography examinations discovered a solid mass in the pelvis. At surgery it appeared to be a metastasis of the pinealoblastoma. It is a very seldom complication of the shunt and various mechanisms are discussed.

[Neuroblastoma of the tail of the pancreas. Apropos of a case].

We describe the case of a four-year-old child who presented a neuroblastoma of the tail of the pancreas. Diagnosis was evoked on computer tomography and confirmed thanks to the pathological examination of the resected tumour. Malignant tumours of the pancreas are rare in children and most of the cases are carcinoma. Three cases of pancreatic neuroblastoma have been described. Evolution and prognosis depend on the staging once the diagnosis is established.
