[Rare causes of ossification of the posterior common vertebral ligament causing cervical compression. Apropos of 2 cases].

The ossification of the posterior longitudinal is always responsible of cervical myelopathy. Radiological study and the CT scan, are able to precise the level, the morphologic and associated abnormalities of this lesion. Two cases of ossification of the posterior longitudinal ligamentum with cervical myelopathy are reported. The radiologic studies determined the etiology, in the first case, it was fluorosis and the second DISH disease.

[Uncommon etiology of cruralgia].

A 58 year old man suffered from low back pain. Physical examination showed asymmetry of the quadriceps and slight motor deficiency of right leg. Plain radiography of the pelvis revealed a large osteophyte, developed anteriorly at the low part of the right sacro iliac joint. CT exam of lumbar spin was normal. But, it confirmed osteophyte of right sacro iliac. Percutaneous injection of a small quantity of xylocaine under CT guidance in the site of the osteophyte behind crural muscle was marked by immediate disappearance of the pain, confirming the site of conflict between the crural nerve and the osteophyte. The patient was treated by injection of corticosteroid at the same location. Recovery was good.

Cerebral candidiasis. Computed tomography appearance.

A three year old child who had been suffering from oral candidiasis since the age of 1 year presented with osteitis of the clavicle, 2 cerebral frontal abscesses and an occipital abscess which extended across the calvaria and was associated with osteolysis. Histological and microbiological studies following surgery confirmed the diagnosis of candidiasis in this girl who was found to have IgA immunodeficiency. The authors report the computed tomographic appearance of the cerebral lesions and review the literature.

[Chylothorax caused by thrombosis of the superior vena cava in Behçet's disease].

The occurrence of chylothorax due to thrombosis of the subclavicular venous drainage is reported. This occurred in a young adult with previously undiagnosed Behçet's disease which had been developing over three years. Venous thromboses during the course of Behçet's disease are extremely frequent and are currently one of the diagnostic criteria. When these thromboses involve the central veins, in particularly the superior vena cava or one of its branches a chylothorax is possible due to blockage of the lymphatic circulation and may be a grave complication, given its location.

[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.

[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.

[Circumscribed non-tuberculous osteomyelitis in children. Apropos of 31 cases].

Over the last eight years (1975-1983) a total of 31 cases of circumscribed non-tuberculous osteomyelitis in children have been treated as against 21 cases of classical acute osteomyelitis, suggesting transformation of the mode of presentation of this disease. Lesions were located in the pelvis (8 cases), the calcaneum (3 cases) and the long bones (20 cases), the metaphysis being affected in the latter in 13 patients, the diaphysis in 4 and the epiphysis in three. Specific radiologic images for each location are defined. Clinical expression was subacute and signs of infection inconstant. Differential diagnosis is discussed in relation to each region involved, a positive diagnosis depending on clinical, biologic and radiologic findings, with the need for biopsy in case of doubt. The latter was necessary in 12 of the 31 children. Diagnosis was confirmed in all cases by the favorable outcome from treatment.

[Superior caval syndrome caused by chronic mediastinitis in Behçet's disease].

We report a case of Behçet disease complicated by superior vena cava syndrome secondary to extrinsic compression by mediastinal fibrosis. This association is not reported in literature. The habituel etiology of vena cava syndrome in Behçet disease is venous thrombosis. Radiological investigations of this syndrome are necessary to avoid an useless anticoagulant therapy.
