[Cystic lymphangioma of the spleen (author's transl)].

A rare form of true non-parasitic cysts of the spleen, cystic lymphangiomas are seen as round calcified images in the left hypochondrium. Bidimensional ultrasonography has considerably simplified the diagnosis of splenic cysts, but modern investigations, which can usually eliminate the presence of hydatid cysts in the spleen, cannot differentiate the various types of non-parasitic cysts. Diagnosis of cystic lymphangiomas, currently made after pathological examinations, can be assisted by needle-puncture aspiration guided by ultrasonography, and the role of this investigatory method in diagnosis and therapy is discussed. The only radical treatment for splenic cysts is splenectomy, which should be conducted routinely because of the difficulty of pre-operative diagnosis and the high risk of severe complications.

Suprasellar choristoma.

A case of choristoma of the posterior lobe of the pituitary is presented. The clinical presentation suggested chromophobe pituitary adenoma and the true diagnosis was only established on histological esamination. Despite the patient's advanced age her-operative course was satisfactory, but the disturbances of endocrine and visual function remained virtually unchanged. Perusal of the literature shows that this is the twentieth case of suprasellar or neurohypophyseal choristoma so far published. It provides an opportunity to review the clinical presentation, radiology and treatment, as well as to discuss the histiogenesis and nature of this rare pituitary tumor.

[Achondrogenesis. Apropos of a case].

The authors report a new case of achondrogenesis, the study of which is principally directed towards the histopathological examination of the conjugal cartilage. A brief review of the literature recalls the main clinical, radiological and histopathological characteristics of this fatal chondrodysplasia transmitted by an autosomal recessive means. In addition to other features, it reveals the difficulty which may be experienced in differentiating between the two types (I and II). Finally, the differential diagnosis is briefly assessed, the problem being the elimination of other non-transmissible chondrodysplasias, in particular thanatophoric dwarfism, for the purpose of appropriate genetic counselling.

[Rectoscopy: a useful tool to diagnose pseudomembranous colitis (author's transl)].

The authors have performed nine rectoscopies in 14 cases of pseudomembranous colitis. A rectoscopic appearance enables eight times out of nine to diagnose the disease, which asserts itself in all cases by biopsies. Out of the nine cases, two had previously undergone an unnecessary laparotomy, and for three cases the diagnosis of rectal tumour established on rectal digital examination is twice set right by rectoscopic appearance and three times by biopsies. In the remaining five cases with mild intestinal symptoms and severe associated disease the diagnosis was only made with autopsies. A systematic rectoscopy with biopsies is indicated in all patients treated with antibiotics who present an unexplained diarrhea, collapsus or acute abdominal syndrom.

[Bronchopulmonary "tumouriet" Rare aetiology of an isolated rounded opacity (author's transl)].

In the case described, the onset of haemoptysis led to the discovery of a rounded opacity at the left base. All investigations being negative, thoracotomy was performed. The diagnosis could then be made by histology. Bronchopulmonary "tumourlets" are rarely seen (184 cases) masses of epithelial cells which are usually discovered by chance within areas of altered pulmonary tissue. Forms with clinical or radiological manifestations are extremely rare, only 4 other cases having been described. The pathogenesis of these tumours has been the object of recent ultrastructural studies which have shown the relationship which exists between "tumourlet" and carcinoid tumour. It would thus seem reasonable to classify "tumourlets" amongst the tumours of the diffuse endocrine system. The authors nevertheless feel that it would be premature to name them as bronchial carcinoids of tumourlet type. The concept of "tumourlet" as a separate entity should be retained.

[Large partially thrombosed pseudo-tumoral aneurysm of the aqueductal area].

Authors are reporting a case of a giant sylvian aneurism partially thrombosed which had given some tumor like symptoms. The Peumography performed, just before an angiography showed the exact size and the malformation's relations with the lateral ventricle. During the operation, the complete removal of the aneurismatic mass had been done. The follow up was good.

[Primary malignant tumor of the liver in children].

Primary malignant tumours of the liver in children are rare. They occur in more than 50% of cases before the age of 2 years. The clinical signs are very often limited to a large mass in the right hypochrondrium. A search for alphafoetoprotein and arteriography are the most useful investigations for diagnosis. The pathology leads one to distinguish hepatoblastomas and hepatocarcinomas. The prognosis in these tumours remains poor for, in spite of progress in liver surgery, a cure is rarely possible. It is important for doctors to recognize the existence of this tumour pathology in order to give a chance for surgery to succeed in these young children. To illustrate this, 5 cases from Besançon are reported here.

[Spinal cord compression caused by spinal aneurysmal bone cyst (author's transl)].

Spinal aneurysmal bone cyst is sufficiently rare for the authors to report this case with rapid evolution and development of paraplegia. Total removal was achieved, and clinical recovery remained complete six months after operation. The pathogenic, clinical, radiological, histological and therapeutic aspects are briefly reviewed and discussed.
