Efficacy of intravenous propranolol for life-threatening diffuse neonatal hemangiomatosis.

Pediatr Dermatol 2022 May 16. Epub 2022 May 16.

Department of Pediatrics, Hamamatsu University School of Medicine, Hamamatsu, Japan.

Oral propranolol is recommended as the first-line agent for infantile hemangioma requiring systemic treatment. Life-threatening complications such as obstructive infantile hemangioma of the airway or infantile hepatic hemangioma associated with high-output congestive heart failure are major indications for the consideration of early treatment. We present the case of an infant with life-threatening diffuse neonatal hemangiomatosis, including airway obstruction due to subglottic hemangioma, heart failure due to multiple hepatic hemangiomas with portohepatic venous shunts, and severe anemia due to continuous gastrointestinal bleeding, in which treatment with intravenous propranolol proved successful.

Classification of hepatic cavernous hemangioma or hepatocellular carcinoma using a convolutional neural network model.

J Gastrointest Oncol 2022 Apr;13(2):787-791

Department of Interventional Radiology, Tangdu Hospital, Fourth Military Medical University, Xi'an, China.

Background: Computed tomography (CT) is a common imaging technique for diagnosis of liver tumors. However, the intensity similarity on non-contrast CT images is small, making it difficult for radiologists to visually identify hepatic cavernous hemangioma (HCH) and hepatocellular carcinoma (HCC). Recently, convolutional neural networks (CNN) have been widely used in the study of medical image classification because more discriminative image features can be extracted than the human eye.

Effect of an Ultrahigh b Value of 3000 s/mm and the Minimal Echo-time on Image Quality and the T2 Shine-through Effect in Diffusion-weighted Imaging of the Liver at 3T: Phantom and Clinical Pilot Studies.

Magn Reson Med Sci 2022 May 11. Epub 2022 May 11.

Department of Radiology, Faculty of Medicine, Kyorin University.

Purpose: To assess the effect of an ultrahigh b value of 3000 s/mm and the minimal TE of 53 ms on image quality and T2 shine-through effect in liver diffusion-weighted imaging (DWI) using a 3-Tesla MRI scanner with a peak gradient of 100 mT/m.

Methods: At b values of 1000 and 3000 s/mm and at the minimal (44-53 ms) and routine TEs (70 ms), DWI of our original phantom and liver DWI in 10 healthy volunteers and 26 patients with 35 hepatic hemangiomas were acquired with this scanner, and the quantified SNR of the phantom and the hepatic parenchyma in the volunteers and the contrast-to-noise ratio (CNR) of the hepatic hemangiomas were calculated; two independent readers qualitatively graded the overall image quality in the volunteers and determined the presence or absence of the T2 shine-through effect related to the hemangiomas in the patients. We compared the SNR and subjective overall image quality between the minimal and routine TEs and the CNR and incidence of the T2 shine-through effect between b values of 1000 and 3000 s/mm.

Imaging Spectrum of Intrahepatic Mass-Forming Cholangiocarcinoma and Its Mimickers: How to Differentiate Them Using MRI.

Curr Oncol 2022 01 30;29(2):698-723. Epub 2022 Jan 30.

Faculty of Medicine, University of Belgrade, Dr Subotica No. 8, 11000 Belgrade, Serbia.

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy, with mass-forming growth pattern being the most common. The typical imaging appearance of mass-forming ICC (mICC) consists of irregular ring enhancement in the arterial phase followed by the progressive central enhancement on portal venous and delayed phases. However, atypical imaging presentation in the form of hypervascular mICC might also be seen, which can be attributed to distinct pathological characteristics. Read More
