ABSTRACT
Introduction. Le but de ce travail etait d'identifier des images scintigraphiques modeles dans la mise en place d'une nouvelle strategie diagnostique des osteonecroses drepanocytaires (OND). Methodes. La scintigraphie osseuse a ete realisee apres injection par voie intraveineuse de 296 a 740 MBq deMDP-Tc99m; selon le poids chez 126 patients. L'interpretation collegiale etait effectuee apres acquisition et traitement des images obtenues au moyen d'une gamma camera. Resultats. Nous avons distingue 4 stades evolutifs de l'OND. Le stade 1 correspondait a une normofixation dans 51% des cas; le 2 a une hypofixation homogene dans 54% de cas; le 3 a une hypofixation cernee d'hyperfixation dans 13% de cas; et le 4 d'evolution tardive;a une hyperfixation homogene dans 31% de cas. Les lesions etaient dans 87 % des tetes femorales; 6 % condylien;3 % des tetes humerales et 2% rachidien. 100 % des necroses retrouvees sur les tetes femorales sieges d'une boiterie; avaient une hyperfixation. Conclusion. La scintigraphie s'avere incontournable pour les drepanocytaires surtout en periode de crise. En effet elle impose une autre attitude dans la prise en charge et l'amelioration du pronostic de l'OND; veritable probleme en sante publique

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.

Over a six-month period, 146 grade IV AIDS patients (HIV-1 and HIV-2) systematically underwent abdominal ultrasound examination. All abdominal organs were investigated in the search for lesions. Many lesions were detected. Pathological lesions were most frequent in the nodes (17.2%), hyperechogenic liver tissue (16.5%) and kidneys (13.7%). Lesions in the liver, gall bladder and spleen were less frequent. In most cases, the lesions were not specific to AIDS. However, systemic abdominal ultrasound scans for AIDS patients would be of value because such lesions are present.

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.
