BACKGROUND: Hemangiomas are common cutaneous findings on healthy infants. These vascular malformations are generally benign, though in rare circumstances they can potentially be fatal. This is particularly true when the hemangiomas are large or numerous and occurring in visceral organs. Previously unrecognized visceral hemangiomas are part of the differential for any neonate presenting unexpectedly in shock. CASE REPORT: A 10-day-old neonate presented to the pediatric emergency department with difficulty breathing...

Purpose To investigate diagnostic performance by using a deep learning method with a convolutional neural network (CNN) for the differentiation of liver masses at dynamic contrast agent-enhanced computed tomography (CT). Materials and Methods This clinical retrospective study used CT image sets of liver masses over three phases (noncontrast-agent enhanced, arterial, and delayed). Masses were diagnosed according to five categories (category A, classic hepatocellular carcinomas [HCCs]; category B, malignant liver tumors other than classic and early HCCs; category C, indeterminate masses or mass-like lesions [including early HCCs and dysplastic nodules] and rare benign liver masses other than hemangiomas and cysts; category D, hemangiomas; and category E, cysts)...

Focal liver lesions are commonly encountered and often demonstrate nonspecific findings at initial imaging. Although most incidentally discovered liver lesions are benign, their noninvasive diagnosis is necessary, especially if they are large or atypical. Imaging characterization of focal liver lesions and exclusion of malignancy are of prime importance, particularly in high-risk populations. Contrast agent-enhanced ultrasonography of liver lesions is both accurate and reproducible for evaluation of benign and malignant liver tumors...

BACKGROUND: Traditionally, open hepatic resection is the first choice of treatment for symptomatic enlarging hepatic hemangiomas, which requires a large abdominal incision and is associated with substantial recovery time and morbidity. Minimally invasive laparoscopic resection has been used recently in liver surgery for treating selected hepatic hemangiomas. However, laparoscopic liver surgery poses the significant technical challenges and high rate of conversion. Radiofrequency (RF) ablation has been proved feasible in the treatment of hepatic hemangiomas with a size range of 5...

Infantile hemangioma is a benign vascular neoplasm that spontaneously involutes over time. Management, when needed, consists of medications, laser treatment and surgical excision. We describe a 3-year-old girl who presented shortly after birth with diffuse cutaneous hemangiomas, hepatosplenomegaly with liver lesions, anemia, and acute heart failure. She was diagnosed with hepatic and cutaneous infantile hemangioma based on skin biopsy. She developed progressive pulmonary hypertension with numerous pulmonary nodules suspicious for pulmonary arteriovenous malformations...

Benign focal liver lesions are a heterogeneous group of tumors of different cellular origin. They might develop from mesenchymal cells, hepatocytes or cholangiocytes. They are more often detected due to the increasing number of imaging investigations and the excellent performance of the new ultrasound machines. The imaging findings have to be interpreted while bearing the patient's clinical context in mind. The aim of this review is to discuss the three most frequent benign focal hepatic lesions : hemangioma, focal nodular hyperplasia and hepatocellular adenoma...

Anastomosing haemangioma (AH) is a recently described, unusual variant of capillary hemangioma that appears to be unique to the genitourinary system, with a particular proclivity for the kidney. AH is a subtype of capillary haemangioma, which is rarely encountered in clinical practice, particularly in the liver. We herein present the case of a 57-year-old woman with an incidental finding on magnetic resonance imaging of a local lesion in the liver, sized 3.3×3.0 cm. The patient underwent hepatectomy with a good postoperative recovery...

Tumours arising from mesenchymal tissue components such as vascular, fibrous and adipose tissue can manifest in the liver. Although histopathology is often necessary for definitive diagnosis, many of these lesions exhibit characteristic imaging features. The radiologist plays an important role in suggesting the diagnosis, which can direct appropriate immunohistochemical staining at histology. The aim of this review is to present clinical and imaging findings of a spectrum of mesenchymal liver tumours such as haemangioma, epithelioid haemangioendothelioma, lipoma, PEComa, angiosarcoma, inflammatory myofibroblastic tumour, solitary fibrous tumour, leiomyoma, leiomyosarcoma, Kaposi sarcoma, mesenchymal hamartoma, undifferentiated embryonal sarcoma, rhabdomyosarcoma and hepatic metastases...
