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.
There is a substantial range of drawbacks and complications associated with the use of self-expanding nitinol stents for palliation of malignant esophageal strictures. A covering would be necessary to prevent tumor ingrowth.
The aim of this study was to retrospectively evaluate 140 patients with severe (97 massive, 43 moderate) haemoptysis treated by bronchial artery embolisation. Between January 1997 and April 2005, 140 patients (120 males and 20 females, aged 23-71 years) with severe haemoptysis considered surgically inoperable because of limited pulmonary reserve were treated by embolisation. The cause of haemoptysis was tuberculosis in 136 patients and malignancy in four. Embolisation succeeded in controlling haemoptysis immediately after the intervention in 138 patients (98.5%) and at 1 month in 126 patients (90%). Severe haemoptysis recurred in 11 patients with prior massive haemoptysis and 3 patients with prior moderate haemoptysis in a mean time of 3.7 months (1-7 months) after the last intervention. The bleeding source was detected during angiography and embolised in 12 of these patients. Two patients with malignant tumour died because of abundant bleeding, following an asymptomatic period of 30 days. There were no procedure-related major complications. Bronchial artery embolisation is a safe and effective palliative treatment alternative in moderate and massive haemoptysis.
The technique of superselective embolization using a coaxial catheter is an effective and safe method in the treatment of post-biopsy AVFs and pseudoaneurysm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
