Jpn J Radiol 2021 May 27. Epub 2021 May 27.

Department of Radiology, Beijing YouAn Hospital, Capital Medical University, Beijing, 100069, China.

Purpose: To investigate and compare the CT and MRI features of hepatic sclerosed hemangioma (HSH) and sclerosing cavernous hemangioma (SCH).

Materials And Methods: Twelve HSH cases and 36 SCH cases were included, the imaging findings on CT (9 HSH and 34 SCH) and MRI (8 HSH and 10 SCH) were analyzed. Qualitative image analysis included the location, size, shape, capsular retraction, density, calcification, signal intensity on T-weighted image (TWI) and T-weighted image (TWI), presence of diffusion restriction, apparent diffusion coefficient (ADC) map, transient hepatic attenuation difference around the lesion, and the dynamic enhancement patterns.

Paediatric focal nodular hyperplasia: A case study of typical contrast-enhanced ultrasound findings with quantitative analysis and correlated with magnetic resonance imaging.

Ultrasound 2021 May 9;29(2):128-134. Epub 2020 Aug 9.

Department of Radiology, King's College Hospital, London, UK.

Introduction: Focal nodular hyperplasia, a benign liver tumour, is the second most common focal benign liver lesion, after a cavernous haemangioma. Contrast-enhanced ultrasound is used increasingly for the diagnostic work up and follow-up of focal liver lesions in adults, but is particularly valuable in the paediatric population, with the ability to reduce radiation and the nephrotoxic contrast agents used in computed tomography or magnetic resonance imaging. Confident recognition of focal nodular hyperplasia is important; it is benign, usually asymptomatic, of no clinical significance, of no clinical consequence or malignant potential. Read More

The humbling hemangioma: uncommon CT and MRI imaging features and mimickers of hepatic hemangiomas.

Clin Imaging 2021 Jun 5;74:55-63. Epub 2021 Jan 5.

NYU Langone Health, Department of Radiology, United States of America.

Cavernous hemangiomas are among the most common liver lesions encountered in abdominal imaging. While classical imaging characteristics usually aid the radiologist in confidently arriving at its diagnosis, atypical hemangiomas can prove to be difficult to distinguish from other more worrisome hepatic lesions such as metastases and hepatocellular carcinoma. Furthermore, some malignant lesions can display features that simulate hemangiomas. Read More

Hepatic hemangiomas: the various imaging avatars and its mimickers.

Radiol Med 2020 Sep 5;125(9):801-815. Epub 2020 Apr 5.

Department of Radiology and Diagnostic Imaging, Faculty of Medicine and Dentistry, University of Alberta, 8440 112 St NW, Edmonton, AB, T6G 2B7, Canada.

Hemangiomas are the most common benign tumors of the liver. These lesions are typically asymptomatic, solitary and almost always discovered incidentally, and in recent years with advances in imaging technology these lesions are being detected more frequently. Although, in majority of the cases, the imaging diagnosis of a liver hemangioma is clearly and confidently established, not all hemangiomas present with their characteristic or typical appearance on imaging.

Automatic Respiratory Gating Hepatic DCEUS-based Dual-phase Multi-parametric Functional Perfusion Imaging using a Derivative Principal Component Analysis.

Theranostics 2019 14;9(21):6143-6156. Epub 2019 Aug 14.

Department of Biomedical Engineering, School of Life Science and Technology, Xi' an Jiaotong University, Xi' an, P. R. China.

: Angiogenesis in liver cancers can be characterized by hepatic functional perfusion imaging (FPI) on the basis of dynamic contrast-enhanced ultrasound (DCEUS). However, accuracy is limited by breathing motion which results in out-of-plane image artifacts. Current hepatic FPI studies do not correct for these artifacts and lack the evaluation of correction accuracy. Read More

Differentiation of Hepatic Sclerosed Hemangiomas From Cavernous Hemangiomas Based on Gadoxetic Acid-Enhanced Magnetic Resonance Imaging Features.

J Comput Assist Tomogr 2019 Sep/Oct;43(5):762-769

Biostatics and Clinical Epidemiology Center, Samsung Medical Center, Seoul, Republic of Korea.

Objective: The objective of this study was to evaluate the imaging features of a hepatic sclerosed hemangioma by comparing them with those of a cavernous hemangioma using magnetic resonance imaging with gadoxetic acid enhancement.

Methods: Nine patients with hepatic sclerosed hemangiomas and 36 patients with cavernous hemangiomas (control group) who underwent gadoxetic acid-enhanced magnetic resonance imaging were included. Qualitative values (imaging findings and enhancement pattern [typical vs atypical enhancement]) and quantitative values (apparent diffusion coefficient) were evaluated. Read More

Hawaii J Med Public Health 2019 04;78(4):128-131

National Cancer Consortium, Walter Reed National Military Medical Center (WRNMMC), Bethesda, MD (WAK).

The majority of giant hepatic cavernous hemangiomas are asymptomatic and can safely be observed. However, when a lesion becomes symptomatic, affecting quality of life or cannot be distinguished from a malignancy, then operative therapy should be considered. We herein present a case of a symptomatic 12cm × 14cm × 17cm "mega" hemangioma (>10cm) of the left hepatic lobe. Read More

Icahn School of Medicine at Mount Sinai, Department of Pathology New York, NY, USA 10029-6574.

Sclerosing hemangiomas of the liver are rare benign tumors of the liver. Although hepatic hemangiomas are the most common benign liver tumor, they are mostly cavernous in nature. A hepatic sclerosing hemangioma is defined by presence of fibrosis and hyalinization as a result of degenerative changes in a cavernous hemangioma. Read More

[Cavernoma complicated with biliopatia secondary to type 1 Gaucher disease: report of a Peruvian case].

Rev Gastroenterol Peru 2018 Jul-Sep;38(3):280-284

Facultad de Medicina Humana, Universidad Nacional San Luis Gonzaga. Ica, Perú; Sociedad Científica de Estudiantes de Medicina de Ica (SOCEMI). Ica, Perú.

Gaucher disease is an autosomal recessive lysosomal storage disorder characterized by deficiency of beta-glucosidase that would lead to the accumulation of glucosylceramide mainly in cells of the mononuclear phagocytic system causing systemic effectations. We present a patient of twenty years who is suffering from chronic pain in the left hypochondrium with episodes of bleeding for 3 years and sensation of thermal rise, physical examination revealed jaundice and massive splenomegaly, without neurological involvement. Severe osteoporosis, pancytopenia, and the presence of portal vein thrombosis with cavernomatous transformation complicated by portal biliopathy simulating a klatskin tumor, marrow and enzymatic studies were compatible with Gaucher disease, were shown as unexpected findings.

Genome-Wide Sequencing Reveals Small Nucleolar RNAs Downregulated in Cerebral Cavernous Malformations.

Cell Mol Neurobiol 2018 Oct 10;38(7):1369-1382. Epub 2018 Jul 10.

International Neuroscience Institute, Rudolf-Pichlmayr-Strasse 4, 30625, Hannover, Germany.

Cerebral cavernous malformations (CCM) are vascular malformations associated with abnormally dilated blood vessels and leaky capillaries that often result in hemorrhages. Despite recent advances, precise understanding of the cellular and molecular mechanism leading to the pathogenesis of CCM remains elusive. Emerging evidence indicates that small nucleolar RNAs (snoRNAs), belonging to the class of non-coding RNAs, may play a significant role as diagnostic markers in human diseases. Read More
