Transient washout of hepatic hemangiomas: Potential pitfall mimicking malignancy
Hemangiomas are the most common tumor of the liver and distinguishing them from malignancy is important. This is a report of 3 hemangiomas in 2 patients that exhibit transient washout of gadoxetate disodium (Eovist), relative to blood pool and liver parenchyma, a characteristic that is used to diagnose hepatocellular carcinoma in at-risk patients. It is important to recognize that high-flow hem...
متن کاملBenign Hepatic Neoplasms
Historically benign liver tumors were encountered incidentally during laparotomy or more re‐ cently during laparoscopy at which time definitive histological diagnosis can be established. However, with the utilization of advanced imaging modalities hepatic neoplasms have been in‐ creasingly identified, with a prevalence rate of up to 50% reported among the general popula‐ tion [1]. Among these i...
متن کاملBenign Hepatic Neoplasms
Hepatic lesions are frequently identified incidentally on • imaging performed for other purposes. With the exception of large lesions, benign hepatic neo• plasms are typically asymptomatic. With current high quality imaging, it is possible to differentiate • the majority of hepatic neoplasms as benign or malignant. Resection of indeterminant, worrisome lesions is generally • preferred over biop...
متن کاملRight trisegmentectomy for hepatic neoplasms.
Thirty patients had right trisegmentectomy for 19 primary hepatic malignant tumors, seven localized liver metastases and four benign lesions. A technical refinement that aided resection of bulky posterior and superior tumors was intrahepatic identification and control of the right hepatic vein. The operative mortality was 3.3 per cent. Late hepatic insufficiency was not observed. More than one-...
متن کاملExpression of epithelial markers in PEComa of sacral ligament: a potential diagnostic pitfall
Perivascular epithelioid cell neoplasm/tumor (PEComa) was a relatively uncommon lesion of mesenchymal origin characterized by perivascular epithelioid cells with distinctive histological and immunohistochemical features. The occurrence in the sacral ligament was exceptional rare. Cytokeratin and epithelial membrane antigen (EMA) were considered as commonly useful epithelial markers to distingui...
