Cutaneous and hepatic vascular lesions due to a recurrent somatic mutation reveal a pathway for vascular malformation.

HGG Adv 2021 Apr 1;2(2). Epub 2021 Mar 1.

Department of Dermatology, School of Medicine, Yale University, New Haven, CT 06510, USA.

The term "cavernous hemangioma" has been used to describe vascular anomalies with histology featuring dilated vascular spaces, vessel walls consisting mainly of fibrous stromal bands lined by a layer of flattened endothelial cells, and an irregular outer rim of interrupted smooth muscle cells. Hepatic hemangiomas (HHs) and cutaneous venous malformations (VMs) share this histologic pattern, and we examined lesions in both tissues to identify genetic drivers. Paired whole-exome sequencing (WES) of lesional tissue and normal liver in HH subjects revealed a recurrent c. Read More

A case of diffuse hepatic hemangiomatosis coexistent with giant hemangioma: case report and literature review.

Radiol Case Rep 2021 Jun 17;16(6):1518-1523. Epub 2021 Apr 17.

Body Imaging, Radiology Department, IBERORAD, Barcelona, Spain.

We report a case of hepatic hemangiomatosis coexistent with a giant hepatic hemangioma diagnosed in the context of the study for SARS-CoV-2 infection. Computed tomography showed irregular contours of the left hepatic lobe with a lesion that compromised the whole lobe, with peripheral uptake and a centripetal tendency in the late phase, compatible with bulky cavernous hemangioma, as well as another lesion with the same characteristics in segment VI. Magnetic resonance imaging of the abdomen showed multiple hepatic hemangiomas observed in both lobes involving all segments, some of them smaller than 1 cm, which were hyperintense in the T2-weighted sequences and showed progressive contrast enhancement.

Chitinase 3-like 1 is a profibrogenic factor overexpressed in the aging liver and in patients with liver cirrhosis.

Proc Natl Acad Sci U S A 2021 Apr;118(17)

Hepatic Pathogenesis Section, Laboratory of Infectious Diseases, National Institute of Allergy and Infectious Diseases, NIH, Bethesda, MD 20892;

Older age at the time of infection with hepatitis viruses is associated with an increased risk of liver fibrosis progression. We hypothesized that the pace of fibrosis progression may reflect changes in gene expression within the aging liver. We compared gene expression in liver specimens from 54 adult donors without evidence of fibrosis, including 36 over 40 y old and 18 between 18 and 40 y old. Read More

Department of Paediatric and Adolescent Surgery, Medical University of Graz, Graz, Austria.

The perinatal management of newborns with giant omphaloceles requires careful suspicion concerning 'unexpected' associated malformations. We describe a newborn with a combination of incomplete Pentalogy of Cantrell consisting of giant omphalocele, anterior congenital diaphragmatic hernia (CDH) and pericardial absence complicated by a hepatic rapidly involuting congenital hemangioma (RICH). A giant omphalocele was detected prenatally. Read More

Eur J Radiol 2021 May 1;138:109620. Epub 2021 Mar 1.

Department of Diagnostic Radiology, Saitama Medical University International Medical Center, 350-1298, Yamane 1397-1, Hidaka, Saitama, Japan.

Purpose: To compare the estimated quantity of intratumor gadoxetic acid retention using T1 mapping of gadoxetic acid-enhanced magnetic resonance imaging (MRI) versus conventional processing methods for the differential diagnosis of focal liver lesions.

Methods: Seventy patients with hepatic lesions (colorectal metastasis (CRM) [n = 28], hepatocellular carcinoma (HCC) [n = 20], hemangioma [n = 12], and intrahepatic cholangiocarcinoma (ICC) [n = 10]) underwent gadoxetic acid-enhanced MRI, including pre- and post-contrast T1-weighted imaging and T1 mapping. Quantitative analyses included the lesion-to-liver signal intensity ratio (SIR) on hepatobiliary phase images, the pre- and post-contrast lesion T1 value difference (ΔT1 [ms]), and the lesion retention index (LRI [%]), which was the estimated intralesional gadoxetic acid retention calculated on pre- and post-contrast T1 maps using a two-compartment pharmacokinetic model.

Metastatic neuroblastoma masquerading as infantile hemangioma in a 4-month-old child.

Pediatr Blood Cancer 2021 May 28;68(5):e28920. Epub 2021 Feb 28.

Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, Ohio.

Introduction: Diffuse liver lesions in an infant have a differential diagnosis including infantile hemangioma (IH), which is common in the first year of life, and neuroblastoma (NBL) which presents at a median age of 18 months.

Results: We describe the case of a 4-month-old girl with a known superficial/deep IH who presented with new axillary nodules and hepatosplenomegaly, initially suspected to reflect IH but later determined to be widely metastatic NBL.

Conclusion: Hepatic IH and metastatic NBL can present similarly. Read More

J Gastrointest Surg 2021 Feb 25. Epub 2021 Feb 25.

Creticos Cancer Center at Advocate Illinois Masonic Medical Center, Chicago, IL, USA.

The management of symptomatic giant hepatic hemangiomas (> 10 cm) varies in the literature. Multiple interventional approaches have been described including surveillance, embolization, enucleation, and resection based on tumor size, location, relationship to vascular and biliary structures, and the quality and quantity of the functional liver remnant. Resection is often performed as a last resort due to the risk of major hemorrhage. Read More

J Clin Med 2021 Feb 9;10(4). Epub 2021 Feb 9.

Division of Vascular and Interventional Radiology, Mayo Clinic Arizona, Phoenix, AZ 85054, USA.

Transarterial embolization has shown promise as a safe, effective, and less invasive treatment modality for benign liver lesions (hemangioma, focal nodular hyperplasia (FNH), and hepatic adenoma (HA)) with fewer complications compared to surgical intervention. There is no consensus regarding the most appropriate embolization material(s) for the treatment of benign liver tumors.
