CONTEXT: Cysts arising from the hepatobiliary tree are a group of heterogeneous lesions with regard to pathogenesis, clinical presentation, and radiological finding. They can be intrahepatic or extrahepatic, developmental, secondary to infective/inflammatory etiologies, as well as neoplastic. This study was conducted to determine the spectrum of hepatobiliary cysts in surgically intervened cases, with regard to their prevalence, histological spectrum, and clinicoradiological correlation, wherever possible...

It remains unclear if single incision laparoscopic liver surgery is superior to standard multiport resections and in what regard patients might benefit from this approach. We retrospectively analyzed the course of all patients undergoing laparoscopic left lateral sectionectomy at our center between 2009 and 2017. In total, 11 single incision and 31 multiport left lateral sectionectomies were performed at our center between July 2009 and May 2017. Six patients were excluded due to multivisceral resections. Indications included adenoma (n = 7 vs n = 2), focal nodular hyperplasia (n = 4 vs n = 3), hepatocellular carcinoma (n = 4 vs n = 4), colorectal liver metastasis (n = 4 vs n = 0), noncolorectal metastasis (n = 2 vs n = 1), hemangioma (n = 3 vs n = 0), abscess (n = 1 vs n = 0), and cysts (n = 1 vs n = 0)...

BACKGROUND: A hepatic sclerosed hemangioma (HSH) is a very rare benign liver tumor. The correct preoperative diagnosis of HSH is very difficult because its features of imaging are similar to those of intrahepatic cholangiocarcinoma or colorectal liver metastasis. CASE PRESENTATION: We experienced five patients who were diagnosed histologically with HSH. The preoperative diagnoses were HSH in two patients, cavernous hemangioma in one, intrahepatic cholangiocarcinoma in one, and colorectal liver metastasis in one...

Transcatheter arterial embolization (TAE) is a method for the treatment of liver hemangioma, but fewer studies reported the long-term result.Retrospective study was conducted to liver hemangioma patients who received TAE. The inclusion criteria included the following: the period of follow-up was more than 5 years; and patients were followed up for less than 5 years, but received surgical treatment due to the enlargement of tumor or severe complications of TAE. The collected data included sex, age, size of the tumor, times of TAE, complications, period of follow-up, long-term result, and whether or not surgery was finally performed...

Liver lesions are often incidentally detected on ultrasound examination and may be incompletely characterized, requiring further imaging. Contrast-enhanced ultrasound (CEUS) was recently approved by the Food and Drug Administration in the United States for liver lesion characterization. CEUS has the ability to characterize focal liver lesions and has been shown to be superior to color Doppler and power Doppler ultrasound in the detection of tumor vascularity. Differentiating benign from malignant liver lesions is essential to characterizing liver lesions...

A number of benign and malignant neoplasms may arise from the vascular elements within the liver parenchyma. Lesions discussed in this article include angiosarcoma, epithelioid hemangioendothelioma, solitary fibrous tumor (hemangiopericytoma), infantile, and cavernous hemangiomas. Despite a common theme of vascular origin, the pathologic and imaging appearance of these entities can be heterogeneous. Angiosarcomas are bizarrely enhancing, highly aggressive tumors, which often present with metastatic disease...

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...
