ABSTRACT
Ascariasis is one of the most common helminthic diseases worldwide. The presence of this worm in the biliary tree causes biliary colic, recurrent pyogenic cholangitis, pancreatitis, hepatic abscesses, and septicemia. The diagnosis of biliary ascariasis is usually made by ultrasound (US). We report the computerized-tomography (CT) aspects that allowed the identification of ascaris in the biliary tract in two patients.

The manifestations of the acquired immunodeficiency syndrome (AIDS) are common in the head and neck and include opportunistic infections, malignancies and diffuse reactive adenopathy. This article reviews the usual and unusual manifestation of AIDS affections of the parotid gland, sinonasal and oral cavity, nasopharynx, temporal bone and neck as analysed by different methods of imaging, particularly by computed tomography.

Calcification in lymphoma before treatment or after chemotherapy is extremely rare. There have been scarse reports of calcified masses due to Hodgkin and non-Hodgkin lymphomas, originating in the main lymphatic chains of the mediastinum and retroperitoneum. We report a case of primarily extra-nodal (pulmonary) non-Hodgkin lymphoma with calcification prior to current treatment.

The authors emphasize the importance of knowing, understanding and identifying the radiation-induced changes in various body organs by radiologists in order to distinguish them from residual or recurrent malignancies. Computed tomography enables the evaluation of the effects and complications of the radiation therapy, besides other image modalities, and its findings are outlined. The clinical correlation, mainly with the time elapsed between the treatment and the examination is very important to establish the diagnosis.

The ultrasonographic study of 33 patients with hepatolenticular degeneration showed the following main changes: disorders of the hepatic echotexture (29 cases), changes of the splenic dimensions (21), liver shrinkage (10), cholelithiasis (8), hepatomegaly and ascites (1). The disorders of liver echotexture exhibited different patterns, from slight to severe changes of the hepatic echogenicity, associated with anatomic distortions of the liver, such as alterations of outline and decrease of dimensions. Liver shrinkage was always accompanied by splenomegaly. The scarcity of hepatomegaly may be explained by the fact that the ultrasonography was performed after the onset of treatment with penicillamine, or by other factors still unknown, copper perhaps possessing a stronger fibrogenetic action than other hepatotoxic agents. Cholelithiasis was very frequent in females (6 of 13 patients), its incidence tending to increase with age. Regarding males there was no increase when the incidence was compared to the general population. The two sole males were young, an unusual finding in normal men.
