Background: Liver hemangiomas (HGs) are characterized by cavernous venous spaces delineated by a lining of vascular endothelial cells and interspersed with connective tissue septa. Typically, a liver HG has higher apparent diffusion coefficient (ADC) and T2 values than those of hepatocellular carcinomas (HCCs) and liver metastases, and lower ADC and T2 values than those of liver simple cysts. However, a portion of HGs shows ADC and T2 overlapping with those of HCC, liver metastasis, and simple cyst.

Article Synopsis
  • Adult diffuse hepatic hemangiomatosis (DHH) is a very rare condition, and this case is the largest reported instance involving both liver lobes with no extrahepatic issues.
  • A 51-year-old man was treated for symptoms like abdominal swelling and difficulty breathing, leading to the discovery of a massive liver lesion determined to be 35.1 × 32.1 × 14.1 cm through imaging and biopsy.
  • The case provides valuable insights into DHH's clinical presentation and imaging characteristics, aiding in understanding this uncommon disease and assisting in the patient's ongoing care and potential liver transplant evaluation.

The discontinuous peripheral enhancement is a pattern of enhancement usually attributed to typical cavernous hemangioma, that is the most common benign solid lesion of the liver. The discontinuous peripheral enhancement, however, may be encountered in many other benign and malignant focal liver lesions as an atypical presentation or evolution, and hemangiomas with discontinuous peripheral hyperenhancement on hepatic arterial phase may not always have the typical post-contrast pattern on portal venous and delayed phases. Therefore, abdominal radiologists may be challenged in their practice by lesions with discontinuous peripheral enhancement.

The identification and accurate diagnosis of focal liver lesions are important in modern medicine, where diagnostic radiology plays an essential role. This review aimed to examine the hyperechogenicity and histopathological features of focal liver lesions. Hyperechogenic liver lesions can be either benign or malignant.

Background: Follow-up is recommended for an asymptomatic unilocular hepatic cystic lesion without wall-thickness and nodular components. A few liver cystic lesions represent biliary cystic neoplasms, which are difficult to differentiate from simple cysts with benign mural nodules on imaging alone.

Case Presentation: An 84-year-old woman with a history of simple liver cyst diagnosed one year prior was admitted for evaluation of a developed mural nodule in the cystic lesion.

Background: Camrelizumab, a programmed death 1 (PD-1) inhibiting antibody, has demonstrated efficacy in various malignancies and received approval in multiple countries. Despite its therapeutic benefits, camrelizumab is associated with a unique spectrum of immune-related adverse effects (irAEs), predominantly reactive cutaneous capillary endothelial proliferation (RCCEP). However, visceral manifestations of such endothelial proliferations, particularly hepatic cavernous hemangiomas, have not been extensively documented.

Giant hepatic hemangiomas are occasional in patients with cirrhosis. It remains a challenge to decide on the need for treatment and choose the most appropriate intervention. A 62-year-old woman was recently diagnosed with cirrhosis and complained of upper abdominal fullness, reduction in oral food intake, and weight loss of 6 kg over the last three years.

Department of General, Interventional and Neuroradiology, Wroclaw Medical University, 50-367 Wrocław, Poland.

Hepatic hemangiomas are the most common benign liver tumors. Typically, small- to medium-sized hemangiomas are asymptomatic and discovered incidentally through the widespread use of imaging techniques. Giant hemangiomas (>5 cm) have a higher risk of complications.

China.

Article Synopsis
  • A 37-year-old woman was hospitalized with a liver mass identified as a hepatic inflammatory myofibroblastic tumor (HIMT), which is mainly seen in adults and has distinct imaging characteristics.
  • HIMT is made up of myofibroblast spindle cells along with plasma cells and/or lymphocytes, but its exact cause is not well understood and may relate to infections or immune responses.
  • Treatment usually requires surgical removal of the tumor, and if that's not fully possible or if there are metastases, chemotherapy or targeted therapies may be used, highlighting the importance of accurate diagnosis and personalized treatment.

Collision tumors consisting of hepatocellular carcinoma (HCC) and cavernous hemangioma (CH) are rare and the clinicopathological characteristics or cause of the tumors remain unclear. The present study reports the case of a 71-year-old male patient who was admitted to Sunshine Union Hospital (Weifang, China) due to a liver mass found during a routine physical examination. computed tomography scans showed a main lesion of ~4.

Lymphangiomas are benign lesions of vascular origin with lymphatic differentiation, most commonly found in the head and neck. Generalized lymphangiomatosis is a very rare condition in adults, which is characterized by a diffuse proliferation of lymphatic vessels. The lymphangioma is composed of lymphatic endothelium-lined cystic spaces.

Objective: Cerebral cavernous malformations (CCMs) are vascular lesions with an overall risk of rupture from 2% to 6% per year, which is associated with significant morbidity and mortality. The diagnostic incidence is increasing, so it is of paramount importance to stratify patients based on their risk of rupture. Data in the literature seem to suggest that specific medications, particularly antithrombotic and cardiovascular agents, are associated with a reduced risk of bleeding.

A physical examination of a 9-month-old female infant presenting with vomiting and diarrhea revealed tenderness in the right upper abdomen and heightened abdominal muscle tone. Abdominal ultrasonography identified an irregular hypoechoic area within the right lobe of the liver. While a subsequent enhanced CT examination disclosed a well-defined lesion exhibiting internal focal calcification and delayed heterogeneous enhancement.

Background: Giant hepatic cavernous hemangioma with multiple satellite nodules is a rare subtype of hepatic cavernous hemangioma, the most common vascular liver tumor. We report on a tumor with unusual histologic features: (1) Finger-like infiltration pattern; (2) lack of encapsulation; (3) blurred tumor/liver interface; and (4) massive satellitosis-referring to the article "Hepatic cavernous hemangioma: underrecognized associated histologic features".

Case Summary: A 60-year-old man presented with increasing uncharacteristic abdominal discomfort and mildly elevated blood parameters of acute inflammation.

Background: Hepatic hemangioma has been one of the absolute indications of laparoscopic hepatectomy (LH). However, the risk of catastrophic intraoperative bleeding and the difficulty to control it make the laparoscopic treatment of giant hepatic hemangioma (GHH) a technical challenge for hepatobiliary surgeons. Herein, we presented a video of LH for GHH using the involved intrahepatic anatomic markers approach.

Cavernous haemangiomas, also known as cavernoma or cavernous angiomas, are clusters of vasculature malformations arising from the endothelial layer of blood vessels. They are commonly found in the central nervous systems, skin, or liver. Rarely, they can also affect adrenal glands, a phenomenon with only 66 cases since the first case was reported in the literature in 1955 and 2018.
