[Appearance on X-ray and computed tomography of femoral head necrosis in patients with sickle cell disease]. / Aspects radiographiques et tomodensitométriques de la nécrose de la tête fémorale chez le drépanocytaire.

The aim of this study was to describe X-ray and computed tomography signs and to estimate the severity of femoral head necrosis in patients with sickle cell disease. We studied two groups of patients with sickle cell disease (group A: 14 patients with no hip pain and group B: 34 patients with hip pain) over 17 months. Each patient underwent hip X-ray (lying face-down) and CT scan. None of the patients in group A presented hip lesions whereas we detected 42 necrotic femoral head lesions by standard X ray and 51 by CT scan. The lesions were frequently bilateral (82.14%) and were more frequent in young patients (from 11 to 30 years old). Their progression was faster in patients with the SS genotype. No significant difference was observed according to type of hemoglobin. All patients with sickle cell disease presenting with hip pain should undergo CT scan to check for femoral head necrosis.

[Contribution of computed tomography in the diagnosis of symptomatic epilepsy]. / Apport de la tomodensitométrie dans le diagnostic étiologique des épilepsies symptomatiques.

The aim of this retrospective study was to document the various causes of epilepsy determined by computed tomography (CT). We studied 205 CT scans carried out in patients with symptomatic epilepsy. We identified 52 (25.36%) pathological causes: 18 cases (34.62%) of infectious lesions, predominantly toxoplasmosis, 9 cases (17.30%) of tumors, 9 cases (17.30%) of vascular lesions and 8 cases (15.39%) of post-traumatic and atrophic lesions. CT is of great value in the diagnosis of epilepsy, not only in the assessment of the disease, but also for identifying the lesion responsible for the seizures, which may be treatable. It is advisable to carry out a CT scan for any patient presenting with symptomatic epilepsy.

[Intra-abdominal small round-cell desmoplastic tumor: ultrasonographic and computed tomographic aspects. Apropos of a case]. / Tumeur desmoplastique intra-abdominale à petites cellules rondes: aspects échographiques et tomodensitométriques. A propos d'un cas.

We report a case of small round-cell desmoplastic tumor located in the abdomen. We describe the ultrasound and CT features of this uncommon tumor with poor prognosis.

[Ultrasound diagnosis of fetal malformations in utero: apropos of 30 cases]. / Diagnostic échographique des malformations foetales in utero: à propos de trente cas.

This study assess the incidence of fetal malformations and the contribution of ultrasound scans to their diagnosis in utero. We reviewed the files of 1,960 pregnant women of whom 30 (1.53%) had malformed fetuses. Ultrasound scanning detected 29 of these cases and failed to detect only one case (an arterial canal malformation). Neurological malformations, particularly hydrocephalus and anencephaly, were most common (12 cases), followed by urinary tract abnormalities (hydronephrosis and renal polycystosis). Other malformations, such as those of the digestive tract, thorax and face, occurred less frequently. Ultrasound scans can be used to decide whether the pregnancy should be continued and what postnatal treatment should be given.
