lesions osseuses de la sarcoidose

Sarcoidosis is a chronic granulomatous disease of undeterminable aetiology affecting multiple organs. Bony affection is rare, and often difficult to be diagnosed. Through observation of two cases we tried to characterize clinically the osseous lesions and their effect on prognosis by clarifing the interest of osseous scintiscanning in the early detection of these lesions. Observation 1: A female patient aged 44 years, treated from pulmonary sarcoidosis since 6 years. Diagnosis of bony sarcoidosis of the right radius has been suspected depending on the clinical picture, radiological and isotopic scanning features. Bone scanning also spotted other lesions in the controlateral left wrist. Observationn 2: A female patient aged 56 years, in whom a neurological sarcoidosis with a cranial bone affection has been diagnosed by a direct osseous scintigraphic bone biopsy. Discussion: Osseous sarcoidosis affection predominates at the hands and feet bones. Often starting, with phalengeal pain tumification. In our observation, bony scintigraphy has been individualised by accurate precession of different diseased sites if compared with standard x. ray images and also by discovering asymptomatic lesions. This exploration also contributes in evaluation of the disease similar to the biological assessment, ensuring early mangement of infammatory attacks

Apport de la scintigraphie dans l'etude de la perfusion pulmonaire

109 patients with different lungs or extra lungs diseases were investigated by perfusion scintigraphy. The r‚sults showed a good sensitivity of this exploration in the diagnosis of pulmonary perfusion and study lung perfusion in different diseases, which constitute advantages to draw up the balance sheet for lesions, their forward and the pulmonary after- effects valuation

Evaluation clinique de la methoxy-isobutyl isonitrile dans le diagnostic et la localisation de l'infarctus du myocarde

The cardial scintrigraphy realised by the new Isonitrile molecules that are indicated in the Technetum 99m, has known a great progress since 1986; In fact, one of its advantages with regard to the TL 201 is the absence of the redistribution phenomena, so no constraint of time is presented even if there is a necessity to inject another does one more. The result of different studies show similar spects to those which occur in the TH 201 to detect the [coronary stenoses]as well as a higher specificity; Finally, the molecule which is indicated in Tc99 m also allows, after the injection of IV, to realise an [isotepical venticulographie] in the first passage
