ABSTRACT
Over five years, 105 patients with hepatic echinococcosis were studied. Plain radiographs of the hepatic area yielded the correct diagnosis in 35% of patients. Intravenous viscerograms were diagnostic in all but 14 of the patients (an accuracy of 83%). Computed tomography was performed in 19 cases and proved the most efficient of the techniques--it was diagnostic in all 19 cases. The radiological signs of this entity are discussed.

Radiological findings in 12 cases of "Mediterranean" lymphoma are analyzed, 4 of which are associated with gammapathy. These findings have not permitted differentiation of this type of lymphoma from those classically described, although there are two signs that strongly suggest this diagnosis: extension of the lesions along wide areas of the small intestine, almost always including the duodenum, and spiculation of the mucosal fold edges, representing massive plasmocyte infiltration of the lamina propria. The principal clinical, immunological, and pathological aspects are described, as well as the radiological differential diagnosis.

The study covered 50 patients suffering from hepatic effusions; a solution used in contrast intravenous psychography was administered to them by the intravenous route, at similar doses to those used in intravenous psychography with infusions. This process which we have called Intravenous Viscerogramme, because of the similarity of the images obtained with those of the viscerographic phase of arteriography, has enabled the diagnosis of 35 hydatidiform cysts, one case of cholangiolar hamartoma and an abscess. Owing to the ease with which it can be carried out, we think that it can be used in the diagnosis of tumoral lesions of the liver. When the result is positive, radiological signs are obtained which enable identification of the lesion, thus avoiding resorting to more complex investigations such as angiography.

Perforation of pulmonary hydatid cysts into the bronchial tree was seen in 56 of 239 cases. The resulting radiological signs are much more specific than those seen prior to perforation. These signs are described and correlated with the cystic structures that give rise to them. Perforation into the pleural cavity, seen in 5 cases, may result in secondary hydatidosis, as happened in one case.
