Sclerosed hemangioma of the liver

Sclerosing hemangioma in the liver

“…Hemangiomas consist of endothelium-lined blood-filled spaces separated by fibrous septa. Cavernous hemangiomas in the liver usually present as solitary well-delineated, subcapsular, discolored nodules that are smaller than 5 cm 3. They can exhibit various forms of pathology, such as necrosis, scarring, and calcification, some of which mimic the primary or metastatic malignancy.…”

Preoperative diagnosis of the sclerosed hemangioma of the liver using multimodality imaging findings: A case report

“…This distinctive structure shows a high characteristic signal intensity on T2-weighted images and a hemodynamic characteristic pattern on enhanced CT or MR imaging, and imaging modalities are highly reliable for diagnosis [17] , [18] , [19] , [20] . However, there are some cases that contain parts of hyaline degeneration, which occurs secondary to thrombus, necrosis, or cicatrization [1] , [2] , [3] , [4] , and is called “sclerosed hemangioma.” This may result in various uncharacteristic findings on radiological imaging [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] . CT and MR imaging features that are suggestive of sclerosed hemangioma include a geographic pattern, capsular retraction, reduction in size over time, and loss of contrast enhancement, and additional characteristic features include the presence of transient hepatic attenuation difference, ring enhancement, and nodular regions of intense enhancement, as seen in a typical hemangioma [4] .…”

“…However the imaging diagnosis has still been difficult to differentiate from malignant tumors, including intrahepatic cholangiocarcinoma and liver metastasis, because a sclerosed hemangioma could show variable MR imaging appearance with various degrees of degeneration, fibrosis, and hyalinization [17] . In fact, all previous cases were preoperatively misdiagnosed as malignant tumors [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] .…”

“…Sclerosed hemangioma of the liver is a rare benign lesion characterized by fibrous replacement and hyalinization of a hepatic hemangioma as a result of degeneration [1] , [2] , [3] , [4] . It has been difficult to correctly diagnose a sclerosed hemangioma with imaging, and in several previous studies, most preoperative diagnoses were intrahepatic cholangiocarcinoma or metastasis [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] . This is because the varying degrees of fibrosis and hyalinization mask the typical signal intensity of magnetic resonance (MR) images and enhanced patterns on the dynamic contrast study, even with the recent advancements in radiological modalities.…”

Multiple hepatic sclerosing hemangioma mimicking metastatic liver tumor successfully treated by laparoscopic surgery: Report of a case

“…Sclerosing hemangioma is a rare type of hepatic hemangioma composed of abundant acellular hyalinized tissue in which small vessels are occasionally seen [1] . Only 17 resected cases, including the present case, with detailed information on patients with hepatic sclerosing hemangioma have been reported in the English literature ( Table 1 ) [3–17] . To the best of our knowledge, this report is the first to describe multiple hepatic sclerosing hemangiomas treated by laparoscopic surgery.…”
