[Case report: the spontaneous course of a giant myelolipoma].

Adrenal myelolipomas are rare benign, non functioning tumors, mostly small and asymptomatic. We report the natural history of a giant adrenal myelolipoma. We could follow with CT the natural progression of the tumor during a 5-year interval.

Mandibulo-acral dysplasia.

We report on a 7 year-old-girl with mandibulo-acral dysplasia. When she was 3 years of age it mimicked scleroderma because of skin atrophy and later on a Hutchinson-Gilford progeria syndrome (HGP). Acro-mandibular dysplasia was diagnosed because of facial hypoplasia and mandibular hypoplasia. The bilateral proximal mid-humeral notch seen in this case is unusual.

Pathological fracture in non-ossifying fibroma with histological features simulating aneurysmal bone cyst.

A 12-year-old-girl presented with a fracture of an osteolytic lesion of the distal radius. A 7-year-old girl presented with a fracture of an osteolytic lesion of the femoral shaft. In both cases it was a non-ossifying fibroma with fracture misdiagnosed at pathology as aneurysmal bone cyst. Fractures through non-ossifying fibromas may alter the histological pattern of the initial lesion in two ways: firstly, by the presence of blood pigments due to the fracture, and secondly, by formation of new bone. Radiological-pathological correlation is essential to avoid histological errors after pathological fracture in a non-ossifying fibroma.

Bilateral cystic lymphangioma of the adrenal gland.

We report the case of a 22-year-old woman with a large, bilateral lymphangiomatous cyst originating from the adrenal glands. Since she was having persistent pain and the diagnosis was uncertain, we did surgery.

Complications of lumbar puncture with injection of hydrosoluble material.

We report two cases of severe disorders after spinal puncture with injection of hydrosoluble material. The first case concerned a 36-year-old woman with intrathecal injection of 125 ml of hydrocortisone acetate. An intracranial occipital hematoma developed. The second case concerned a 26-year-old man with intrathecal injection of contrast media and hydrocortisone. A chemical meningitis occurred. In both cases the natural course was favorable. Both complications are well known but rare. A review of the literature is made with description of the mechanisms. Preventive therapeutic measures are reported.

[Medical structures in Vietnam].

In Vietnam, medical structures are organized according to administrative areas. The large cities are divided into sectors each with several quarters. Each region of the country is divided into districts grouping together several small towns. Each small town or city quarter has an infirmary and the districts or city sectors have a small hospital. Larger hospitals are located in the different regions or large cities. Primary patient care is provided by the infirmaries which can refer to small district or quarter hospitals; the more severe cases are then referred to the regional or large city hospitals. Students entering medical school are selected among secondary school graduates by a special entry examination. After a 6-years medical curriculum, hospital interns are chosen by an internship examination. Internship lasts 3 years for all specialties. Specialists and general practitioners work in hospitals or state medical services. Private practice is authorized after working hours.

Fibrous tumours in children: imaging features of a heterogeneous group of disorders.

BACKGROUND: Fibrous tumours are predominantly soft tissue lesions which are relatively frequent in childhood but are little known. Imaging is often used in the evaluation of these tumours but their characteristics, particularly on US or MRI, have not been studied systematically. OBJECTIVES: To provide an overview of the clinical and imaging features of the different disorders, and to correlate them with the currently used classification schemes. MATERIAL AND METHODS: Twenty-five patients with fibrous tumours were evaluated retrospectively. Clinical histories were studied for the histopathological diagnosis, age, signs and symptoms at presentation, mode of therapy and follow-up where available. Imaging findings were analysed for the following variables: number, location, size, margin and architecture of soft tissue and/or visceral lesions and the presence and pattern of osseous involvement. Comparison with the available literature was performed. RESULTS: The following tumour types were encountered: desmoid fibromatosis (n = 9), myofibromatosis (n = 7), fibromatosis colli (n = 2), congenital-infantile fibrosarcoma (n = 2), adult-type fibrosarcoma (n = 2), fibrous hamartoma of infancy (n = 1), angiofibroma (n = 1) and hyaline fibromatosis (n = 1). CONCLUSIONS: While some tumours were non-specific in their clinical and radiological manifestation, others such as myofibromatosis, fibromatosis colli, fibrous hamartoma of infancy and angiofibroma exhibited a characteristic pattern which allowed a diagnosis to be made even without histology.
