    Notes: Abstract Self-expanding nitinol stents were used in 22 patients for palliative treatment of malignant esophagogastric strictures. All patients but 5 were men (age range 47–75 years). The strictures were caused by squamous cell carcinoma (n = 12), adenocarcinoma (n = 8), and recurrent anastomotic carcinoma (n = 2). No technical failure or procedural complications occurred. After the procedure, the severity of dysphagia decreased at least one grade in all patients. Tumor ingrowth into the stent was seen in 7 patients of 22 (32%). Four of these patients were treated with additional stents, and in 3 patients, due to refusal, only balloon dilations were performed, which caused temporary relief. Tumor ingrowth into the stent was noted from 10 days to 7 months (mean 3 months). This seems to be a disadvantage of nitinol stents. At the end of the study 10 patients had died dead with a mean survival of 3 months (range 1 week to 6 months) and 12 patients were still alive with a mean follow-up of 4 months (range 1–8 months). It is concluded that nitinol stents provide satisfactory palliation in patients with malignant dysphagia with neglectable procedural morbidity and mortality rates.

    CT staging of alveolar echinococcosis of the liver (1995)

    Notes: Abstract The purpose of this study was to assess the usefulness of a new staging scheme for alveolar echinoccocosis un of the liver. A total of 28 patients with hepatic alveolar echinococcosis underwent CT examinations and were staged according to the proposed staging scheme (stage 1: lesion measuring less than 3 cm in diameter; stage 2: lesion greater than 3 cm, confined to less than three hepatic segments; stage 3 a: lesion with invasion of more than three hepatic segments; stage 3 b: invasion of liver hilum or suprahepatic vena cava; stage 4: invasion of surrounding organs and/or distant metastasis). Of the patients 16 underwent laparotomy, and results of the radiologic staging were correlated with surgical data. The CT findings correlated well with surgical findings. Patients were followed-up for a period of 6 months to 7 years. We concluded that the proposed staging scheme seemed to be useful for the therapeutic planning of patients with alveolar echinococcosis of the liver.

    Hydatid disease with unusual localization (2000)

    Notes: Abstract. Hydatid disease (HD) may develop in almost any part of the body. The liver is the most frequently involved organ (75 %), followed by the lung (15 %) and the remainder of the body (10 %). Hydatid cysts with unusual localizations may cause serious problems in the differential diagnosis. In this article the various imaging findings of hydatid cysts with unusual localizations are reviewed, based on our experience. Findings in brain, heart, pericard, kidney, intraperitoneum, retroperitoneum, bone, soft tissue, and breast are discussed. Hydatid disease should be considered in the differential diagnosis of all cystic masses in all anatomic locations, especially when they occur in areas where the disease is endemic. The combination of clinical history, imaging findings, and serologic test results usually help the diagnosis.

    MR urography findings of a duplicated ectopic ureter in an adult man (2000)

    Notes: Abstract. In this report we present the imaging findings in an adult male with a duplicated ectopic ureter which inserted into the prostatic urethra. The appearances at excretory urography, US, CT, and MR urography are described together with the potential pitfalls of the imaging techniques. Both US and MR urography accurately image the collecting system from the kidney to the point of distal ureteral insertion, and in our patient, MR urography provided similar information to US.

    Grading of liver lesions caused by Echinococcus granulosus (1993)

    Notes: Abstract The availability of different therapeutic alternatives in hydatid liver disease necessitates a comprehensive classification system in order to evaluate indications and monitor results. We have proposed a new scheme in which lesions are graded 1–5 according to the morphology of the cyst and the presence of findings in favour of cyst rupture. Ultrasound (US), CT and cholangiographic findings in 214 hydatid liver lesions in 152 patients who underwent surgery within 15 days of their radiological examinations were evaluated retrospectively. Results of the radiological classification were correlated with surgical data. We found that purely cystic unilocular lesions never ruptured, that dilatation of biliary canaliculi around a lesion with a complex morphological appearance is a non-specific finding and that there was no reliable radiological sign for a simple biliary communication. US, CT and cholangiography were reliable in diagnosing intra-biliary and direct ruptures. We conclude that the proposed grading scheme could be useful in monitoring the results of different therapeutic modalities for hydatid disease of the liver and, with the accumulation of further data, could be helpful in allocating patients to therapeutic alternatives.
