Multiple paragangliomas: about two cases

The multiple paragangliomas are rare tumours, with slow evolution, posing diagnostic and therapeutic problems. The carotid and jugulo-tympanic localization are the most frequent, and the aortic localization is very infrequent. The association of two, three and four localization is possible in the multiple forms. These multiple localizations are more frequent in familial forms. Surgical removal is the first intention treatment of these tumours. In the multiple forms, the therapeutic strategy must be adapted to each case: usually, the intervention begins by the carotid localization. We report two cases of chemodectoma with multiple localizations. The first case is a 44 years-old woman, who presented a double localization: carotid (bilateral) and aortic (arch). The second case is a patient with a double aortic localization, carotid and aortic, associated to a tympano-jugular localization. Surgical treatment was performed for all these localization, except for the tympano-jugular localization, treated by embolization. The post-operative periods were uneventful. The first case had adjunctive radiotherapy.     

Idiopathic renal vein thrombosis. About two cases

Renal vein thrombosis is a rare pathology difficult to diagnose. It has quite various clinical expressions and biological consequences. The diagnosis is based upon radiologic explorations. This entity may have various causes. Detecting this condition may lead to restoration of renal function compromised by renal vein thrombosis. The treatment of renal vein thrombosis is mainly medical and based on anticoagulants. The role of fibrinolytic treatment is controversial. Surgery is exceptional. We report two cases of idiopathic thrombosis of the renal vein in adult patient. Also, we have done a review of the literature on this clinical syndrome and its diagnostic and therapeutic aspects.
