Le cas presente est une fistule arterioveineuse (FAV) tres volumineuse de l'hemisphere cerebral droit, chez une patiente âgee de 76 ans. L'allure evolutive a ete particuliere car longtemps asymptomatique, puis traduite par des signes trompeurs et enfin compliquee d'une hemorragie cerebro-meningee mortelle

A lymphography was performed as a diagnostic procedure in a 69-year-old female patient hospitalized for protracted fever. Akinetic mutism with left hemiparesis occurred 10 minutes after the injection of ultrafluid lipiodol. The patient died 13 days later. Neurologic complications of lymphography are extremely rare but may be life-threatening. Speculations as to the mechanisms which may be responsible for these complications, through a modification of the usual distribution of the contrast media, include lymphovenous shunts, lymphatic vessel compression or obstruction, pulmonary arteriovenous shunts and right-to-left intracardiac shunts. These mechanisms may facilitate cerebral embolization of the contrast media. Indications of lymphography must be restricted in patients with patent lymphatic obstruction.

Cardiac localizations in hydatid disease are uncommon and often latent. A mass at the apex of the heart was discovered in a 42-year-old patient who presented with abnormal EKG repolarization. This mass was anechoic. Coronography demonstrated an avascular lesion with displaced coronary arteries. A hydatid cyst was suspected. No other visceral localizations of hydatid disease were detected. The patient refused surgery and was seen two years later with acute pericarditis and rapidly developing cardiac tamponade. A very large amount of pericardial fluid and a single hydatid cyst were discovered upon surgery. The cyst was aspirated and sterilized and the protruding cyst wall was resected. A severe postpericardotomy syndrome and positivation of hydatid disease serological tests occurred during the postoperative course. The patient was then given flubendazole. Prompt recovery occurred and the patient is still doing well under therapy two years later. In hydatid disease, an isolated cardiac localization is uncommon and often latent and may be revealed by complications. Prompt diagnosis should be made by echocardiography.
